Moderately Hard Water May require detergent adjustments
Hard Water Increased spotting, filming, and mineral deposits
Very Hard Water Often requires water softening and specialty detergents

If your facility has hard water, choose detergents specifically formulated to combat mineral buildup and maintain glassware clarity.

Consider Soil Levels

Not all foodservice operations generate the same types of food soil.

A coffee shop washing cups and saucers has very different cleaning requirements than a steakhouse processing heavily greased cookware, pans, and serving dishes.

Soil Type Cleaning Challenge
Grease and Oils Require stronger degreasing action
Proteins Can bake onto surfaces if not properly removed
Starches May leave residue and film
Burnt-On Food Requires aggressive cleaning formulations
Beverage Residue Can affect glassware clarity

Improved Safety Minimizes direct chemical handling
Better Compliance Supports sanitation procedures

Automated systems are particularly valuable in high-volume kitchens where consistency is critical.

Consider Operating Costs

The least expensive detergent is not always the most economical solution.

When evaluating costs, consider the total warewashing program rather than the price per container.

Cost Factor Why It Matters
Concentration Levels Highly concentrated products may last longer
Cost Per Rack Provides a more accurate measure of operating expense
Chemical Consumption Impacts monthly operating costs
Maintenance Requirements Poor detergent performance may increase service needs
Water Treatment Costs Hard water may increase detergent usage
Rewash Rates Poor cleaning results increase labor and utility costs

A higher-quality detergent often reduces overall operating costs through improved efficiency, fewer rewashes, and reduced machine maintenance.
