Detergent is a cleaning chemical formulated to loosen and remove soil, grease, food residues and other contaminants from surfaces, utensils and equipment. In a commercial kitchen, detergents are used during the cleaning stage before sanitizing. A detergent removes soil; it does not automatically sanitize or disinfect a surface.
Detergents contain surfactants and other ingredients that help water wet a surface, loosen grease and suspend soil so it can be rinsed away. Different products are formulated for different applications, such as manual dishwashing, machine dishwashing, degreasing floors or cleaning food-contact equipment.
Cleaning removes food residue, grease and visible soil. Sanitizing reduces microorganisms on a cleaned food-contact surface to the required level using an approved chemical or heat process. A surface must be cleaned before it can be effectively sanitized because remaining soil can interfere with the sanitizer.
Follow the product label for dilution, temperature, contact time, rinsing requirements and compatible surfaces. Store chemicals in their original labelled containers or approved secondary containers, away from food and food-contact items. Never mix cleaning chemicals unless the manufacturer explicitly instructs it.
Chef’s tip: Train staff to identify the correct detergent for each task and to follow the full clean-then-sanitize procedure. More concentrated chemical is not automatically more effective and can create residue or safety hazards.
Key distinction: Detergent is a cleaning agent; sanitizer is used after cleaning to reduce microorganisms on food-contact surfaces.
