Back-of-house cleaning requires a defined boundary because kitchens contain heat, grease, food-contact surfaces, sharp tools, chemicals, and powered equipment. A routine scope may cover accessible floors, baseboards, walls, doors, exterior equipment surfaces, employee areas, and selected prep-zone surfaces after the restaurant has removed food, utensils, and loose items.
Degreaser selection, dwell time, agitation, and rinsing must suit the surface. Too much chemical can leave residue, while the wrong product can damage aluminum, finished flooring, grout, or stainless steel. Safety Data Sheets should be available for commercial chemicals, and products must never be mixed unless the manufacturer specifically permits it.
Exhaust hood systems, ducts, fans, grease traps, pest control, and internal appliance servicing are specialist work and should be handled under separate scopes by qualified providers. Keeping those boundaries clear prevents a routine janitorial visit from being mistaken for technical kitchen maintenance.
