Daily wipe-downs keep a commercial kitchen running, but they don't reach the grease that builds up inside hoods, behind equipment, and in floor drains. That buildup is what fails health inspections, trips fire-suppression audits, and drives up pest activity. The right deep-clean frequency depends on how hot and heavy your line runs — not a single blanket rule.
| Area | Typical frequency | Why |
|---|---|---|
| Exhaust hoods & ductwork | Every 3–6 months (monthly for 24-hr or high-volume frying) | NFPA 96 fire code and most insurance policies require documented cleaning based on cooking volume |
| Kitchen floors & drains | Weekly deep scrub, daily degrease of hot zones | Grease + moisture on tile grout is the #1 slip-and-fall and pest-attractant risk |
| Walk-in coolers & freezers | Monthly | Condensation and spills freeze into buildup that's harder to remove the longer it sits |
| Ovens, fryers & line equipment | Weekly to bi-weekly | Carbon and oil buildup affects cooking consistency and equipment lifespan |
| Grease traps/interceptors | Every 1–3 months | Most municipal codes (including Seattle) require regular pump-outs to avoid fines and backups |
A high-volume fryer or wok station generates airborne grease far faster than a light-prep kitchen. Restaurants running 24 hours or frying continuously should treat the "every 6 months" hood-cleaning guideline as a maximum, not a target — many end up on a 60–90 day cycle instead.
King County and most commercial property insurers require a documented, dated cleaning log for hoods and grease traps. If you can't produce that log during an inspection or after a fire claim, you risk a citation or a denied claim — regardless of how clean the kitchen actually looks.
Older ductwork, tight service corridors, and equipment that's hard to pull out for cleaning all extend the time (and cost) of a deep clean, which is a reason to schedule more frequent, smaller cleans rather than deferring to one large annual job.

If any of those sound familiar, it's worth scheduling a deep clean before your next health inspection or insurance audit rather than after.
We build a recurring deep-clean schedule around your cooking volume, health-code requirements, and staffing hours.
