Best Chemicals for Cleaning Ovens, Grills, and Griddles

Commercial ovens, grills, and griddles are exposed to grease, oil, sauces, food particles, smoke, and high temperatures throughout the day. Over time, these materials can harden into thick layers of burnt-on residue and carbonized buildup that ordinary dish soap cannot remove effectively.

If this buildup is allowed to remain, it may create unpleasant odors, produce smoke, transfer burnt flavors to food, reduce cooking efficiency, and make equipment more difficult to maintain. Heavy grease accumulation around burners, heating elements, drip trays, and ventilation areas may also contribute to increased fire risk.

Choosing the correct cleaning chemical is essential because commercial cooking equipment can contain several different materials, including stainless steel, cast iron, chrome-plated steel, aluminum, porcelain enamel, glass, rubber gaskets, and nonstick coatings. A strong chemical that works well on a stainless steel oven interior may discolor aluminum, damage painted components, or reduce the lifespan of a chrome griddle surface.

The best product depends on the type of equipment, level of buildup, surface material, cleaning frequency, and whether the area comes into direct contact with food.

This guide explains the best chemicals for cleaning commercial ovens, grills, and griddles, how different formulations work, when to use each type, and how to protect equipment and employees during routine and deep cleaning.

Quick Answer

The best chemicals for cleaning commercial ovens, grills, and griddles generally include:

• Heavy-duty alkaline degreasers
• Caustic oven and grill cleaners
• Carbon and burnt-on grease removers
• Non-caustic foaming degreasers
• Griddle cleaning liquids or packets
• Enzyme-based degreasers
• Neutral cleaners for final surface wiping
• Manufacturer-approved cleaners for specialty surfaces

For thick, carbonized grease inside ovens or on durable grill components, a commercial alkaline or caustic cleaner is usually the most effective option. For daily maintenance and lighter grease, a lower-caustic or non-caustic degreaser may be easier and safer to use.

Chrome-plated griddles, aluminum parts, nonstick coatings, and self-cleaning ovens often require specialized or manufacturer-approved products. Always verify surface compatibility, follow label directions, wear the required personal protective equipment, and rinse food-contact surfaces as directed.

Why Specialized Cleaning Chemicals Are Necessary

Ordinary dish soap can remove fresh oil and light food residue, but it is usually not strong enough to dissolve grease that has been heated repeatedly.

When cooking oil is exposed to high temperatures, it begins to oxidize, polymerize, and bond to the cooking surface. Food particles may then become trapped in the grease and harden into a dark carbon layer.

This buildup is commonly found on:

• Oven walls and racks
• Grill grates
• Charbroiler components
• Griddle plates
• Fryer exteriors
• Burner covers
• Drip trays
• Salamander broilers
• Range tops
• Backsplashes
• Equipment legs and casters

Specialized commercial kitchen cleaners are formulated to break these deposits apart more efficiently than general-purpose products.

They may help:

Cleaning Benefit	Why It Matters
Break down animal fats and cooking oils	Makes greasy equipment easier to wipe and rinse
Loosen carbonized food	Reduces the amount of aggressive scraping required
Penetrate thick buildup	Improves deep-cleaning performance
Reduce scrubbing time	Lowers labor requirements
Improve heat transfer	Helps equipment reach and maintain temperature more efficiently
Reduce smoke and odors	Removes residue that burns during cooking
Protect food quality	Reduces the risk of burnt flavors transferring to food
Support sanitation programs	Helps maintain cleaner foodservice operations
Extend equipment life	Reduces long-term damage caused by grease and carbon accumulation

The strongest available chemical is not always the best choice. The goal is to use the least aggressive product that can remove the buildup without damaging the equipment.

What Makes Oven, Grill, and Griddle Buildup Difficult to Remove?

Cooking equipment develops several types of soil at the same time.

Fresh Grease

Fresh oil and grease remain soft and can often be removed with a mild degreaser, hot water, and a non-abrasive cleaning tool.

This type of soil is easiest to remove at the end of each shift before it hardens.

Polymerized Oil

Repeated heating causes oil to form a sticky, varnish-like coating. This residue is more difficult to remove than fresh grease and usually requires an alkaline degreaser.

Carbonized Food

Food particles exposed to extreme heat burn and harden onto the surface. These deposits may require a heavy-duty carbon remover, controlled dwell time, and mechanical agitation.

Smoke and Soot Residue

Smoke residue can accumulate inside ovens, around ventilation openings, and on nearby stainless steel surfaces. It may leave a dark, oily film that requires degreasing rather than simple dusting.

Sugars and Sauces

Sugary marinades, barbecue sauces, glazes, and syrups can burn quickly and form hard deposits. These soils may need soaking or repeated applications of a compatible cleaner.

Mineral Deposits

Steam ovens and combination ovens can develop scale from mineral-rich water. Grease removers are not designed to remove mineral scale, so a manufacturer-approved deliming product may be necessary.

Types of Chemicals for Cleaning Ovens, Grills, and Griddles

Commercial cooking equipment may require different chemicals depending on the type of grease, level of carbon buildup, equipment material, and cleaning schedule. Some products are intended for light daily maintenance, while others are formulated for periodic deep cleaning of heavily neglected surfaces.

The strongest cleaner is not always the best option. Choosing a product that is too aggressive may damage aluminum, chrome, painted components, gaskets, coatings, or control panels. A properly matched cleaner should remove soil efficiently without shortening the life of the equipment.

1. Heavy-Duty Alkaline Degreasers

Heavy-duty alkaline degreasers are among the most widely used cleaning chemicals in commercial kitchens. They are formulated to break down fats, cooking oils, proteins, and greasy food residue.

These cleaners are often available in concentrated, ready-to-use, spray, and foaming formulas. Concentrates can be diluted for different cleaning tasks, while ready-to-use products simplify application and reduce mixing errors.

Best For

• Oven interiors
• Grill grates
• Griddle surrounds
• Fryer exteriors
• Range tops
• Range hoods
• Backsplashes
• Drip trays
• Greasy stainless steel surfaces
• Equipment legs and casters

Advantages

Advantage	Why It Matters
Strong grease removal	Breaks down thick layers of oil and food residue
Broad kitchen use	Suitable for many durable cooking and preparation surfaces
Multiple formats	Available as concentrates, sprays, foams, and ready-to-use products
Reduced scrubbing	Helps soften grease before agitation
Flexible dilution	Some concentrates can be adjusted for light or heavy soil
Fast action	May work quickly when used according to the recommended temperature and dwell time

Limitations

Strong alkaline products may discolor, corrode, or damage:

• Aluminum
• Galvanized metal
• Painted surfaces
• Some plastics
• Rubber seals
• Chrome finishes
• Polished surfaces
• Specialty coatings

Do not assume that a degreaser is safe simply because the equipment appears to be stainless steel. Commercial appliances may contain aluminum trim, painted panels, plastic controls, and coated internal components.

Always check both the cleaner label and equipment manual before use.

Best Use

Heavy-duty alkaline degreasers are most appropriate for moderate-to-heavy grease that has not yet hardened into a thick carbon layer. They are often used during weekly cleaning or as part of scheduled kitchen deep-cleaning procedures.

2. Caustic Oven and Grill Cleaners

Caustic oven and grill cleaners contain highly alkaline ingredients, which may include sodium hydroxide or potassium hydroxide. These chemicals react with fats and oils, helping dissolve severe grease and carbonized deposits.

They are among the strongest cleaning products commonly used in commercial kitchens and should be reserved for compatible equipment and difficult buildup.

Best For

• Heavily soiled oven interiors
• Charbroilers
• Grill racks
• Rotisserie components
• Broiler pans
• Drip trays
• Burnt-on grease
• Thick carbon deposits
• Neglected removable components

Advantages

Advantage	Why It Matters
Very high cleaning strength	Removes deposits that mild products cannot dissolve
Carbon penetration	Softens hardened black residue
Reduced scraping	Helps limit aggressive manual abrasion
Faster deep cleaning	Can reduce labor on heavily soiled equipment
Vertical cling options	Foam and gel formulas remain on walls and doors longer

Limitations

Caustic cleaners can cause serious chemical burns, eye injuries, and respiratory irritation. They may also damage equipment if applied to incompatible materials or left on the surface too long.

They are generally unsuitable for:

• Aluminum
• Chrome-plated griddles
• Nonstick coatings
• Painted finishes
• Self-cleaning oven liners
• Heating elements
• Electrical components
• Control panels
• Rubber gaskets unless specifically approved

Safe Use Requirements

Depending on the label and Safety Data Sheet, caustic products may require:

• Chemical-resistant gloves
• Safety goggles
• Face protection
• Protective aprons
• Long sleeves
• Adequate ventilation
• Thorough rinsing
• Restricted access to the cleaning area

Never apply a caustic cleaner to hot equipment unless the manufacturer specifically identifies an approved temperature range.

3. Carbon and Burnt-On Grease Removers

Carbon removers are formulated for blackened, baked-on residue that ordinary degreasers cannot easily dissolve. These products are especially useful when oil and food particles have been repeatedly exposed to high cooking temperatures.

Some are supplied as sprays, gels, or brush-on liquids. Others are designed for immersion tanks where removable components soak for a specified period.

Best For

• Oven racks
• Grill grates
• Burner components
• Broiler pans
• Cooking trays
• Rotisserie parts
• Range components
• Hood filters where approved
• Heavily carbonized removable parts

Advantages

Advantage	Why It Matters
Penetrates hardened deposits	Helps loosen severe carbon accumulation
Reduces scraping time	Minimizes aggressive manual cleaning
Supports soaking	Useful for overnight or extended cleaning cycles
Restores neglected parts	Can improve the condition of heavily soiled equipment
Reaches detailed areas	Soaking solutions can clean around corners and openings

Immersion-Tank Carbon Removers

Immersion systems allow removable equipment parts to soak in a prepared chemical solution. This approach may be practical for high-volume kitchens that regularly clean racks, grates, pans, and filters.

Before soaking any component, confirm:

• The metal is compatible with the solution.
• The part contains no electrical components.
• The product is diluted correctly.
• The recommended water temperature is followed.
• The maximum soak time is not exceeded.
• The part can be rinsed thoroughly afterward.

Aluminum, soft metals, coated components, and certain plastics may be damaged by immersion cleaners.

Limitations

Carbon removers are often highly alkaline and may require the same handling precautions as caustic oven cleaners. They should not be treated as general-purpose cleaning chemicals.

4. Non-Caustic Foaming Degreasers

Non-caustic degreasers are generally milder than traditional caustic oven cleaners. Many rely on surfactants, solvents, or lower-alkaline formulations to loosen grease without using highly corrosive ingredients.

Foaming products are especially useful on vertical surfaces because they remain in place longer than thin liquids.

Best For

• Daily oven cleaning
• Oven doors
• Grill exteriors
• Splash guards
• Stainless steel surfaces
• Range hoods
• Equipment sides
• Moderately soiled appliances
• Facilities seeking lower-odor options

Advantages

Advantage	Why It Matters
Easier handling	Often less aggressive than caustic cleaners
Broader compatibility	May be suitable for more surfaces
Useful for frequent cleaning	Supports daily or end-of-shift maintenance
Improved dwell time	Foam clings to walls and vertical panels
Controlled application	Reduces runoff into electrical or sensitive areas
Lower odor options	May be more comfortable in occupied kitchens

Limitations

Non-caustic products may:

• Require more dwell time
• Need additional agitation
• Perform poorly on thick carbon
• Require repeated applications
• Be less effective on long-neglected equipment

These products work best when grease is removed regularly before it becomes heavily baked onto the equipment.

5. Griddle Cleaning Liquids and Packets

Commercial griddle cleaners are formulated specifically for flat-top cooking surfaces. Many are designed to loosen grease, food residue, and light carbon while reducing the need for aggressive scraping.

Some products are applied while the griddle remains warm. Others require the surface to cool to a particular temperature. The approved temperature range must be followed carefully.

Best For

• Flat-top grills
• Steel griddles
• Restaurant cooktops
• High-volume breakfast stations
• Burger grills
• Sandwich grills
• Teppanyaki-style cooking surfaces where approved

Common Griddle Cleaning Tools

Griddle cleaning systems may be used with:

• Griddle pads
• Pad holders
• Squeegees
• Scrapers
• Heat-resistant gloves
• Absorbent cloths
• Griddle screens where approved

Surface Compatibility

Griddle plates may be constructed from different materials, and each requires appropriate care.

Griddle Surface	Recommended Approach
Standard Steel	Use an approved commercial griddle cleaner
Chrome-Plated Steel	Use a product specifically labeled for chrome
Polished Steel	Avoid excessive abrasion and harsh chemicals
Cast Iron	Use a compatible cleaner and restore seasoning as needed
Stainless Steel	Use a non-abrasive stainless-compatible formula
Coated Surface	Follow the equipment manufacturer’s instructions only

Using the wrong cleaner or abrasive tool on a chrome griddle can permanently scratch, cloud, or reduce the reflective finish.

6. Enzyme-Based Degreasers

Enzyme cleaners use biological compounds to break down fats, oils, proteins, and other organic residue. They are generally intended for preventive maintenance rather than removal of severe carbon deposits.

These products may continue working on organic soil during the recommended dwell period, provided the temperature and conditions support enzyme activity.

Best For

• Light-to-moderate grease
• Routine maintenance
• Floors around cooking equipment
• Equipment exteriors
• Drains where specifically labeled
• Grease traps where approved
• Lower-odor cleaning programs
• Food residue in difficult-to-reach areas

Advantages

Advantage	Why It Matters
Often less corrosive	May reduce risk to compatible surfaces
Lower odor	Can be more comfortable for employees
Preventive cleaning	Helps control grease before it hardens
Organic soil breakdown	Targets fats, oils, and protein residue
Useful around equipment	Can support floor and drain maintenance

Limitations

Enzyme cleaners may not:

• Work quickly on thick grease
• Remove hardened carbon
• Perform well at extreme temperatures
• Remain effective when mixed with incompatible chemicals
• Replace periodic deep cleaning

They are generally more appropriate for routine maintenance than restoration cleaning.

7. Neutral Cleaners for Final Wipe-Downs

Neutral cleaners are mild products designed for light soil and routine surface maintenance. They are not strong enough to remove heavy oven grease or carbon, but they can be useful after stronger cleaning chemicals have completed the main task.

Best For

• Stainless steel exteriors
• Control panels
• Handles
• Equipment surrounds
• Painted surfaces where approved
• Light daily soil
• Final residue removal
• Nearby counters and walls

Advantages

Helps remove residue	Can support the final cleaning stage
Easier rinsing	Often leaves less chemical residue
Broad maintenance use	Practical for exterior and surrounding surfaces

Limitations

Neutral cleaners will not effectively remove:

• Thick grease
• Hardened oil
• Burnt food
• Black carbon
• Heavy smoke residue

Use them as maintenance or finishing products rather than substitutes for heavy-duty degreasers.

Best Chemical by Cleaning Task

Cleaning Task	Recommended Chemical
Light daily grease	Neutral cleaner or non-caustic degreaser
Fresh oil on equipment	Mild alkaline or enzyme-based cleaner
Moderate grease buildup	Heavy-duty alkaline degreaser
Greasy vertical surfaces	Foaming degreaser

How to Choose the Right Cleaner

Selecting a cleaner begins with identifying the equipment material, type of soil, and cleaning conditions. Do not choose a product based solely on cleaning strength.

Identify the Equipment Surface

Before applying a chemical, determine whether the surface is:

• Stainless steel
• Carbon steel
• Chrome-plated
• Cast iron
• Aluminum
• Porcelain-coated
• Painted
• Glass
• Nonstick
• Specialty coated

A cleaner suitable for stainless steel may stain aluminum, damage chrome, soften paint, or degrade a specialty coating.

Surface Compatibility Guide

Surface	General Cleaning Consideration
Stainless Steel	Usually tolerates alkaline cleaners, but avoid chloride-heavy or highly abrasive products
Carbon Steel	May require drying and seasoning after cleaning
Chrome	Use only chrome-approved, non-abrasive products
Cast Iron	Avoid prolonged soaking and restore seasoning
Aluminum	Avoid highly alkaline or caustic cleaners
Porcelain Enamel	Avoid abrasive pads and products that can dull the finish
Painted Panels	Use mild cleaners and avoid strong solvents
Nonstick Coatings	Follow manufacturer instructions and avoid abrasives
Glass Doors	Use a compatible non-abrasive cleaner
Control Panels	Apply mild cleaner to a cloth rather than spraying directly

Evaluate the Level of Buildup

Cleaner strength should match the condition of the equipment.

Light Soil

Light soil includes fresh oil, fingerprints, crumbs, and recent food residue.

Use:

• Neutral cleaner
• Non-caustic degreaser
• Mild alkaline cleaner
• Enzyme-based cleaner

Moderate Grease

Moderate grease may appear sticky, darkened, or layered but has not fully carbonized.

Use:

• Commercial alkaline degreaser
• Foaming degreaser
• Griddle cleaning liquid
• Stronger enzyme formulation where appropriate

Heavy Carbon and Burnt-On Residue

Heavy buildup is usually black, hardened, and resistant to routine wiping.

Use:

• Caustic oven cleaner
• Carbon remover
• Immersion-tank cleaner for compatible removable parts
• Manufacturer-approved deep-cleaning system

Consider Cleaning Frequency

Cleaning frequency affects the level of chemical strength required.

Cleaning Schedule	Typical Product
After Each Use	Mild or griddle-specific cleaner
End of Shift	Non-caustic degreaser
Weekly	Heavy-duty alkaline degreaser
Monthly Deep Clean	Caustic or carbon-removal product
As Needed	Immersion or restoration cleaner

Daily removal of fresh grease can reduce the need for aggressive chemicals later.

Check the Required Equipment Temperature

Some cleaners are formulated for:

• Cold surfaces
• Cool equipment
• Warm griddles
• Specific operating temperature ranges

Applying a chemical outside its approved temperature range may:

• Cause rapid evaporation
• Produce strong vapors
• Reduce cleaning performance
• Damage the surface
• Increase splashing
• Create employee exposure risks

Never apply an oven or grill cleaner to hot equipment unless the product label specifically permits it.

Review Dwell Time

Dwell time is the period the chemical must remain wet on the surface before agitation or rinsing.

A longer dwell time can help soften grease, but leaving the product in place beyond the recommended period may cause discoloration or corrosion.

Follow the label rather than allowing chemicals to dry on equipment.

Check Food-Service Suitability

Choose products labeled for commercial kitchen or foodservice use.

For food-contact surfaces:

1. Remove food and utensils from the area.
2. Apply the cleaner according to the label.
3. Allow the required dwell time.
4. Scrub or wipe as directed.
5. Rinse thoroughly when required.
6. Remove all visible chemical residue.
7. Sanitize afterward when required by the facility procedure.
8. Allow the surface to dry or return it to service as directed.

Do not assume every degreaser is approved for direct food-contact surfaces.

Consider Odor and Ventilation

Strong oven and grill cleaners may release noticeable odors or irritating vapors.

Before use:

• Turn on approved ventilation.
• Keep employees away from the immediate area.
• Remove exposed food.
• Avoid spraying near flames or ignition sources.
• Follow any respiratory protection requirements.
• Do not use the chemical in a confined area without adequate airflow.

Evaluate Training Requirements

A cleaning product should be practical for the employees who will use it.

Premeasured packets, labeled spray bottles, dilution-control systems, and written procedures may reduce:

• Overuse
• Mixing errors
• Inconsistent results
• Chemical waste
• Employee exposure
• Surface damage

The easiest product to use safely may be a better choice for daily cleaning than a highly concentrated chemical requiring complex dilution.

Caustic vs. Non-Caustic Cleaners

Step-by-Step Cleaning Process

Cleaning commercial ovens, grills, and griddles requires more than applying a strong degreaser and wiping the surface. The equipment must be shut down safely, loose debris should be removed first, the cleaner needs enough dwell time to work, and all chemical residue must be removed before the equipment returns to service.

Always follow the equipment manufacturer’s instructions, the cleaning chemical label, your facility’s food safety procedures, and applicable workplace requirements.

Step 1: Turn Off the Equipment

Switch off the oven, grill, or griddle and follow the manufacturer’s shutdown procedure.

Depending on the equipment, this may include:

• Turning off gas or electrical power
• Closing fuel valves
• Allowing fans to stop
• Disconnecting removable electrical components
• Waiting for the cooking surface to reach the approved cleaning temperature

Some griddle cleaners are designed for use on warm surfaces, while many oven and grill cleaners must only be applied after the equipment has cooled.

Do not estimate the correct temperature. Follow the chemical label and equipment manual exactly.

Cleaner Type	Typical Surface Condition
Caustic oven cleaner	Usually cool or within a specified temperature range
Griddle cleaning packet	Often used on a warm surface
Foaming degreaser	Usually cool or slightly warm equipment
Enzyme cleaner	Applied within a manufacturer-specified temperature range
Neutral cleaner	Generally used on cool surfaces

Applying a product to equipment that is too hot may cause rapid evaporation, splashing, strong fumes, or surface damage.

Step 2: Remove Loose Debris

Before applying chemicals, remove loose food, grease, ash, crumbs, and carbon.

Suitable tools may include:

• Approved scraper
• Nylon brush
• Grill brush
• Griddle squeegee
• Disposable towel
• Microfiber cloth
• Hand broom and dustpan for cooled equipment

Removing loose material allows the cleaner to contact the hardened grease underneath.

Pay particular attention to:

• Corners
• Drip trays
• Door edges
• Burner areas
• Grease channels
• Griddle troughs
• Rack supports
• Fan covers

Do not force debris into drains unless the facility’s plumbing and waste procedures specifically allow it.

Step 3: Remove and Separate Components

Where permitted, remove racks, trays, grates, grease pans, burner covers, and other detachable parts.

Place them in a designated wash area or approved soak tank.

Separating components provides better access to:

• Interior oven walls
• Burner assemblies
• Grease channels
• Rack supports
• Hidden carbon deposits
• Drip areas

Before soaking a part, confirm that it does not contain:

• Electrical connections
• Sensors
• Coatings that may be damaged
• Aluminum or other incompatible metals
• Rubber components not approved for immersion

Keep parts organized so they can be reinstalled correctly.

Step 4: Apply the Cleaner

Apply the cleaning chemical according to the label.

Depending on the product, you may:

• Spray it directly onto the surface
• Apply it with a brush
• Use a foaming applicator
• Pour a premeasured griddle packet onto the plate
• Add concentrate to an immersion tank
• Apply gel to vertical oven walls
• Wipe the product on with a cloth

Use only the amount needed to cover the soil.

Avoid applying cleaner to:

• Electrical components
• Pilot assemblies
• Ignition systems
• Thermostats
• Heating elements
• Motors
• Wiring
• Sensors
• Insulation
• Control panels

When working near sensitive areas, apply the chemical to a cloth or brush instead of spraying directly.

Step 5: Allow the Proper Dwell Time

Dwell time is the amount of time the cleaner must remain on the surface to break down grease and carbon.

Do not wipe the product away immediately unless the instructions tell you to do so.

Proper dwell time helps:

• Soften baked-on grease
• Loosen carbon deposits
• Reduce manual scrubbing
• Improve chemical efficiency
• Lower the risk of surface scratching caused by excessive scraping

Longer dwell time is not always better. Highly alkaline cleaners may stain, corrode, or damage surfaces if left in place too long.

Keep the cleaner wet during the approved dwell period, but do not reapply unless permitted by the label.

Step 6: Agitate the Surface

After the cleaner has had time to work, loosen the remaining soil with a surface-appropriate tool.

Possible tools include:

• Non-scratch pad
• Griddle pad
• Nylon brush
• Grill brush
• Approved scraper
• Griddle squeegee
• Soft cloth
• Manufacturer-approved grill brick

Match the tool to the surface.

Surface	Recommended Tool
Standard steel griddle	Approved griddle pad or scraper
Chrome griddle	Non-abrasive pad approved for chrome
Stainless steel oven	Nylon brush or non-scratch pad
Porcelain-coated grate	Soft or non-abrasive brush
Cast iron grate	Approved stiff brush
Oven glass	Non-scratch pad or glass-safe scraper
Coated surface	Manufacturer-approved tool only

Do not use steel wool, harsh abrasive pads, grill bricks, or metal scrapers on chrome, polished, coated, nonstick, or delicate finishes unless the manufacturer specifically permits them.

Step 7: Remove Dissolved Grease

Use a scraper, squeegee, cloth, brush, or wet vacuum where appropriate to remove the loosened grease and chemical solution.

Collect waste in the correct container rather than pushing it onto floors or into drains.

For griddles, direct liquid into the grease trough only when the cleaning procedure and equipment design allow it.

Replace dirty cloths and rinse water as needed. Using contaminated tools can spread grease back onto the equipment.

Step 8: Rinse or Wipe Thoroughly

Remove all remaining cleaning chemical according to the product label.

This may require:

• Potable water
• Damp cloths
• Multiple rinse passes
• A squeegee
• Clean disposable towels
• A wet vacuum
• A final neutral rinse where directed

Food-contact surfaces must not retain cleaner residue.

Continue rinsing until:

• No foam remains
• No visible chemical film is present
• The surface no longer feels slippery
• No cleaner odor remains where applicable
• Rinse water runs clear

Do not assume one wipe is sufficient after using a concentrated or caustic cleaner.

Step 9: Sanitize if Required

Cleaning and sanitizing are separate steps.

Cleaning removes:

• Grease
• Food residue
• Carbon
• Dirt
• Chemical buildup

Sanitizing reduces microorganisms on a previously cleaned food-contact surface.

After cleaning and rinsing, apply an approved sanitizer if required by:

• Your food safety plan
• Local regulations
• The equipment manufacturer
• Facility procedures

Follow the sanitizer label for:

• Concentration
• Contact time
• Application method
• Rinsing requirements
• Air-drying instructions

Do not apply sanitizer over visible grease or cleaner residue.

Step 10: Dry and Reassemble

Allow all cleaned components to dry completely.

Then:

1. Inspect removable parts.
2. Reinstall racks, trays, grates, and grease pans.
3. Confirm that components are positioned correctly.
4. Restore cast iron or carbon steel seasoning where required.
5. Reconnect approved components.
6. Wipe control panels and handles.
7. Inspect the equipment before restarting it.

Moisture left on cast iron or carbon steel may contribute to corrosion.

Step 11: Inspect Before Returning to Service

Before the equipment is used again, check for:

• Remaining grease
• Cleaner residue
• Loose components
• Damaged seals
• Blocked burners
• Improperly installed grates
• Moisture near electrical parts
• Scratched or discolored surfaces
• Unusual odors

Only return the equipment to service after it has been cleaned, rinsed, reassembled, and inspected according to the required procedure.

Best Chemicals for Commercial Ovens

Commercial ovens may develop baked-on grease, smoke film, food spills, carbon, and mineral scale. The best product depends on the oven type, interior material, and level of buildup.

For Daily Oven Cleaning

Use:

• Non-caustic oven cleaner
• Foaming degreaser
• Mild alkaline cleaner
• Neutral cleaner for handles and exterior panels

These products are most effective when spills and grease are removed before they become carbonized.

For Heavy Oven Buildup

Use:

• Caustic oven cleaner
• Heavy-duty alkaline degreaser
• Carbon remover
• Approved soaking solution for racks and trays

Severe buildup may require multiple cleaning cycles rather than one prolonged chemical application.

Oven Areas to Clean

Oven Area	Typical Soil	Suggested Cleaner
Interior walls	Baked-on grease	Oven cleaner or foaming degreaser
Racks	Carbon and food residue	Carbon remover or approved soak solution
Door glass	Grease and smoke film	Oven-glass-safe cleaner
Door seals	Food residue	Mild manufacturer-approved cleaner
Fan covers	Grease	Compatible degreaser
Trays	Burnt food	Carbon remover or soak solution
Handles	Fingerprints and grease	Neutral cleaner
Exterior panels	Light grease	Non-caustic degreaser

Avoid spraying heating elements, fans, sensors, electrical connections, insulation, or control components unless the manufacturer specifically approves wet cleaning in those areas.

Self-Cleaning and Combi Ovens

Self-cleaning ovens and combi ovens may require proprietary:

• Cleaning tablets
• Detergent cartridges
• Rinse products
• Deliming chemicals
• Automated cleaning cycles

Substituting a general oven cleaner may damage internal components or affect warranty coverage.

Follow the manufacturer’s programmed cleaning process.

Porcelain-coated grates	Mild non-abrasive cleaner
Broiler pans	Heavy-duty degreaser
Drip trays	Alkaline degreaser
Grill exterior	Non-caustic foaming cleaner
Burner covers	Manufacturer-approved cleaner
Splash guards	Foaming degreaser

Removable grates may benefit from soaking, but the cleaner must be compatible with the metal and coating.

Cast Iron Grill Care

Cast iron requires additional attention because prolonged soaking and harsh chemicals can remove seasoning and promote rust.

After cleaning:

1. Rinse the grate thoroughly.
2. Dry it immediately.
3. Heat it briefly if permitted to remove moisture.
4. Apply a thin layer of approved cooking oil.
5. Re-season according to the manufacturer’s directions.

Porcelain-Coated Grill Grates

Avoid aggressive metal brushes and hard scrapers that can chip the coating.

Once porcelain coating is damaged, the exposed metal may corrode.

Best Chemicals for Commercial Griddles

Griddles require cleaners that remove grease and food residue without damaging the cooking plate.

The correct chemical depends heavily on whether the surface is standard steel, chrome-plated, cast iron, stainless steel, or specially coated.

For Standard Steel Griddles

Common Mistakes to Avoid

Using a Cleaner That Is Too Strong

Stronger is not always better.

Highly caustic cleaners can damage:

• Aluminum
• Chrome
• Coatings
• Painted panels
• Rubber seals
• Plastic controls
• Polished finishes

Use the mildest product capable of removing the soil effectively.

Applying Cleaner at the Wrong Temperature

A chemical designed for a warm griddle may evaporate rapidly on an excessively hot surface. A cool-surface oven cleaner may create hazardous fumes if applied too early.

Always follow the approved temperature range.

Skipping Dwell Time

Removing a cleaner before it has had time to work increases scrubbing and may leave carbon behind.

Allow the full labeled dwell time.

Leaving Cleaner on Too Long

Excessive dwell time can cause:

• Staining
• Corrosion
• Discoloration
• Coating damage
• Difficult rinsing

Do not allow strong cleaners to dry on the equipment.

Failing to Rinse Thoroughly

Residual cleaner may:

• Affect food flavor
• Create odors
• Damage metal
• Interfere with sanitizing
• Create employee or customer safety concerns

Rinse until the surface is free from visible residue.

Using Abrasive Tools on Chrome

Chrome surfaces require non-abrasive chemicals and tools.

Aggressive scrubbing can permanently damage the finish.

Mixing Chemicals

Combining products may release hazardous gases or create violent reactions.

Never mix cleaners unless the manufacturer explicitly directs it.

Spraying Electrical Components

Do not spray motors, ignition systems, controls, thermostats, wires, sensors, or heating elements.

Apply product to a cloth for nearby surfaces.

Using the Same Tools Across Cleaning Zones

A grill brush or cloth should not be reused on:

• Floors
• Restrooms
• Drains
• Waste containers
• Raw food areas

Use dedicated, color-coded tools.

Ignoring Nearby Grease Sources

Grease can quickly return when:

• Hood filters are dirty
• Grease trays overflow
• Ventilation is inadequate
• Adjacent equipment is heavily soiled
• Walls and backsplashes remain greasy

Clean the entire cooking area, not only the visible cooking surface.

Common Cleaning Problems and Solutions

Problem	Likely Cause	Recommended Solution
Carbon remains after cleaning	Cleaner too mild or dwell time too short	Use a compatible carbon remover
Surface becomes discolored	Cleaner too strong or incompatible	Stop use and consult the manufacturer
Grease returns quickly	Nearby surfaces or ventilation system remain dirty	Clean the full cooking zone
Chemical odor remains	Incomplete rinsing	Rinse again with potable water
Griddle scratches appear	Abrasive tool used	Switch to approved non-abrasive tools
Cleaner evaporates immediately	Surface too hot	Allow equipment to reach the approved temperature
Excessive scrubbing required	Dwell time skipped	Let the cleaner work before agitation
Rust develops	Cast iron or steel left wet	Dry and season the surface

Frequently Asked Questions

What is the best chemical for cleaning a commercial oven?

A heavy-duty alkaline or caustic oven cleaner is usually the most effective option for baked-on grease and carbon inside a compatible commercial oven.

For daily or weekly maintenance, a non-caustic foaming cleaner may be easier to handle and less likely to damage sensitive components.

Always confirm the oven’s interior material and manufacturer recommendations before selecting a product.

What chemical removes burnt-on grease?

Caustic oven cleaners and carbon removers are generally the strongest options for burnt-on grease.

They work by breaking down hardened fats and carbon deposits, but they may require:

• Chemical-resistant gloves
• Eye protection
• Ventilation
• Controlled dwell time
• Thorough rinsing

Use them only on approved surfaces.

Can degreaser be used on a griddle?

Yes, but only when the degreaser is approved for the griddle’s material and operating conditions.

Standard steel griddles may tolerate approved alkaline cleaners, while chrome, coated, and polished surfaces often require specialized products.

Do not use a general kitchen degreaser without checking compatibility.

What is the safest cleaner for daily grill maintenance?

A non-caustic commercial degreaser is often a practical choice for daily maintenance because it is generally less aggressive than a caustic oven cleaner.

However, safe use still depends on:

• The label
• Surface compatibility
• Required PPE
• Proper dilution
• Adequate rinsing

Can oven cleaner be used on aluminum?

Many caustic oven cleaners can corrode, darken, or discolor aluminum.

Do not use an oven cleaner on aluminum unless the product label specifically states that it is compatible.

Do I need to sanitize a griddle after cleaning?

A griddle is a food-contact surface, so it must be returned to a condition that meets your facility’s food safety procedure.

This may include:

1. Cleaning
2. Thorough rinsing
3. Sanitizing where required
4. Air drying or heating according to procedure

Follow the equipment manufacturer, sanitizer label, and applicable local requirements.

Can I use household oven cleaner in a commercial kitchen?

Commercial kitchens should use products appropriate for professional foodservice equipment and workplace procedures.

Household products may not be suitable for:

• Commercial surfaces
• High-volume buildup
• Staff training programs
• Workplace chemical labeling
• Large-scale application
• Foodservice rinsing procedures

Select a product specifically labeled for the intended commercial use.

Are enzyme cleaners strong enough for ovens?

Enzyme cleaners can help remove light grease and organic residue, but they are generally not strong enough for thick carbonized oven deposits.

They are better suited to preventive maintenance than restoration cleaning.

What cleaner should be used on a chrome griddle?

Use only a cleaner specifically labeled for chrome griddles.

Pair it with:

• A chrome-safe pad
• Soft cloth
• Approved scraper
• Griddle squeegee

Avoid grill bricks, abrasive pads, harsh powders, and aggressive metal tools unless the manufacturer explicitly approves them.

Why does grease return after cleaning?

Grease may reappear when:

• Cleaner residue was not fully removed
• Grease was spread rather than lifted
• Hood filters are dirty
• Ventilation is inadequate
• Surrounding equipment remains greasy
• The cooking surface is over-oiled
• Drip trays or grease channels are full

Inspect the complete cooking station rather than repeatedly cleaning only one area.

Can a grill brick be used on every griddle?

No. Grill bricks are commonly used on some standard steel griddles, but they may scratch chrome, polished, or coated surfaces.

Check the equipment manual before using any abrasive tool.

Should oven racks be soaked overnight?

Only if the soaking product permits overnight use and the rack material is compatible.

Exceeding the approved soak time may cause corrosion, discoloration, or finish damage.

How can cleaning chemicals be kept off electrical components?

Apply the cleaner to a cloth, brush, or pad instead of spraying directly near:

• Controls
• Wiring
• Thermostats
• Ignition systems
• Sensors
• Motors

Use minimal moisture around electrical areas and follow the equipment manual.

Why does an oven smoke after cleaning?

An oven may smoke after cleaning if:

• Grease remains
• Cleaner residue was not fully rinsed
• Water or chemical has entered an unsuitable area
• A coating was damaged
• Debris remains near a heating element

Turn the equipment off and inspect it before continued use.

Can hot water improve degreaser performance?

Warm water may improve the performance of some degreasers, but temperature should only be adjusted according to the product label.

Excessively hot water can:

• Increase fumes
• Cause splashing
• reduce enzyme effectiveness
• Damage surfaces
• create employee exposure risks

Conclusion

The best chemical for cleaning an oven, grill, or griddle depends on the equipment material, type of soil, amount of buildup, and cleaning frequency.

Heavy-duty alkaline and caustic cleaners are effective for baked-on grease and carbon during deep cleaning. Non-caustic foaming degreasers are generally better suited to daily maintenance, while specialized griddle products help protect steel, chrome, and coated cooking surfaces. Carbon removers are useful for heavily neglected racks and grates, and neutral cleaners are appropriate for final wipe-downs and exterior maintenance.

Chemical selection is only one part of an effective cleaning program. Proper shutdown, debris removal, dwell time, agitation, rinsing, sanitizing, drying, tool maintenance, and employee training all affect the final result.

Always match the cleaner to the equipment, follow the label, use the required personal protective equipment, and remove all chemical residue before returning food-contact surfaces to service. A consistent cleaning schedule can improve cooking performance, reduce labor, limit smoke and odors, and help extend the working life of commercial kitchen equipment.
