Cleaning removes grease, crumbs, and other soil. Sanitizing reduces microorganisms on a cleaned surface when the correct product, concentration, and contact time are used. Disinfecting is a separate process intended for suitable surfaces and must follow the product label. These terms are not interchangeable.
In food preparation areas, product selection must match the surface and the restaurant's food-safety procedures. Sanitizer concentration can be checked with the test strips specified for that chemistry. Food, utensils, single-service items, and exposed ingredients must be protected before nearby cleaning begins. A product should never be mixed with another chemical unless its manufacturer expressly directs it.
Commercial kitchens also contain materials that need different treatment. Stainless steel can show streaks or suffer damage from unsuitable chemicals. Quarry tile and grout collect greasy soil differently than luxury vinyl tile in a dining room. Rubber mats need cleaning on both sides and a safe place to dry. Grease on a floor may require an appropriate degreaser, controlled dilution, agitation, recovery of the dirty solution, and enough drying time before employees return.
Routine janitorial cleaning does not replace hood and exhaust-system service, grease-trap pumping, pest control, equipment repair, or fire-suppression inspection. The written scope should state these boundaries clearly. Restaurants remain responsible for meeting requirements set by the Guilford County health authorities and the North Carolina Food Code.
