Ask for a scope that names the equipment, surfaces, and access conditions included in the price. Terms such as “deep clean” can mean very different things. A clear proposal should state whether work covers appliance exteriors, removable parts, areas under equipment, walls, floors, drains, storage fixtures, or only selected zones.
The provider should also explain preparation. Hot equipment cannot be cleaned safely, and chemicals should never be applied casually around food, exposed utensils, electrical controls, pilot assemblies, or sensitive finishes. Safety Data Sheets should be available for cleaning products, and chemical use should follow product labels. Sanitizing, when requested and appropriate, is a separate step performed after a surface has first been cleaned.
Commercial kitchen cleaning is also distinct from servicing fire-suppression systems or cleaning an entire exhaust system. Filters, hoods, ducts, and fans may have separate access and service requirements. Confirm these boundaries in writing so the scheduled work matches what your operation expects.
