Restaurant Kitchen Deep Clean Checklist: What Gets Cleaned, What Gets Documented
What a deep clean covers that a daily close doesn't
A daily kitchen close covers the surfaces your team can reach during a normal shift — the flat-top, the fryer baskets, the prep tables, the floor. It doesn't cover the inside of the oven, the bottom of the fryer vat below the drain, the grease that builds up on the underside of equipment, or the duct work above the hood filters.
A deep clean addresses those areas. Done on a regular schedule — typically aligned with your slower days or seasonal closures — it gives you a kitchen that's cleaner than a daily close alone can achieve, and it creates a documented record of the work.
The deep clean scope: what should be included
Not every vendor uses the same scope. Before you schedule a kitchen deep clean, confirm in writing what's included. Here's what a thorough restaurant kitchen deep clean should cover:
- Hood and exhaust system: The hood canopy, plenum, grease filters, duct runs, and exhaust fan. This is often done as a separate service from the rest of the kitchen deep clean, with before/after photos provided.
- Fryers: Full drain and clean of the vat, including the lower drain area. The outside of fryer cabinets and the grease trap connection.
- Ovens and ranges: Interior oven walls, door gaskets, burner grates, drip pans, and the area under the range on the floor.
- Flat-top griddles: Full de-grease of the cooking surface, drip trays, and grease channel. The sides and underside of the unit.
- Prep tables and cold side: Under refrigerated prep tables, the inside of lowboy refrigerators, and the floor beneath them.
- Walls and ceiling tiles: Grease splash on walls behind the cooking line, ceiling tiles above the hood if they've accumulated grease or smoke.
- Floor drains: Clear debris, clean drain grates, flush the drain line to the floor drain.
- Dish area: Inside the dishwasher door and chamber, the drain below the machine, and the wall behind the machine.
What documentation to request
For the hood and exhaust portion, request before/after photos and a written service record. That documentation is what your fire marshal or insurer will want to see.
For the rest of the kitchen deep clean, a written scope document confirming what was cleaned and when is enough for most operators. Some franchise and multi-unit operators request photos of specific areas — ask your vendor what they can provide.
Planning the schedule
The right schedule for a kitchen deep clean depends on your volume and your slower windows. Some options operators use:
- A full close on a slow day — often Monday for restaurants that are closed Sundays
- A closing-to-opening window on a weeknight, starting after last service and ending before morning prep
- A seasonal close — the week after Thanksgiving or between Christmas and New Year's, when volume drops and staffing allows for a thorough reset
Hood cleaning is typically done as a separate visit from the rest of the deep clean, since the exhaust system requires specific equipment and produces its own cleaning waste. Coordinate the two visits so your documentation is current.
What to do after the deep clean
File the documentation. Take a photo of the service record and store it with your other compliance records — your most recent fire inspection report, your most recent health inspection, your insurance policy documents. The documentation from a deep clean is worth nothing if you can't find it when you need it.
