Both jobs get called “cleaning the kitchen,” so owners assume one covers the other. It doesn’t, and that gap is how a spotless kitchen still fails a fire inspection.
Everyday kitchen cleaning keeps your surfaces, floors, and equipment clean and safe day to day. Hood and exhaust cleaning is a separate, NFPA 96 certified job that degreases the entire exhaust system, from the hood down to the rooftop fan, so the hidden grease can’t catch fire. You need both.
A daily wipe does nothing for the grease packed inside your ductwork, and a once a year exhaust cleaning does nothing for tonight’s spills. There’s one spot both jobs touch, and it’s exactly where kitchens get it wrong.
Knowing which job covers what tells you who to call and keeps you off the wrong end of a fire marshal’s report.
What everyday kitchen cleaning covers
Everyday kitchen cleaning is the routine work that keeps the space running clean. Your staff handles the daily version during and after service; a professional crew handles the deeper recurring version after hours.
It covers:
- Wiping and sanitizing prep surfaces, tables, and contact points
- Degreasing cook line equipment, ranges, fryers, and stainless
- Sweeping, mopping, and scrubbing floors and drains
- Cleaning the hood exterior and washing the baffle filters
- Restrooms, trash, and the dining room
This is real grease work. A professional crew brings heat, the right chemistry, and dwell time to pull grease off surfaces the way we describe in our guide to how professionals degrease a commercial kitchen. What it does not touch is the inside of your exhaust system.
What hood and exhaust cleaning covers
Hood and exhaust cleaning is a specialized fire safety job. It degreases the complete exhaust path that carries smoke and grease out of your kitchen:
- The hood canopy and the plenum behind the filters
- The full run of ductwork through the wall and roof
- The rooftop exhaust fan and its housing
- The access panels along the way, opened, scraped, and sealed back up
This is governed by NFPA 96, the fire code standard for commercial kitchen ventilation, and it has to be done by a certified exhaust cleaning company that documents the work with its technician’s certification. The crew arrives with pressure washers, containment, and the training to dismantle and degrease every section of the system. It’s the grease you can’t see, in the places a mop will never reach, that starts kitchen fires.
Hood and exhaust cleaning vs everyday kitchen cleaning, side by side
| Everyday kitchen cleaning | Hood and exhaust cleaning | |
|---|---|---|
| What it cleans | Surfaces, floors, equipment, hood exterior, filters | Hood interior, ductwork, plenum, rooftop fan |
| Who does it | Your staff and your janitorial crew | An NFPA 96 certified exhaust company |
| How often | Daily to weekly, plus periodic deep cleans | Monthly to yearly by cooking volume |
| Main purpose | Sanitation, appearance, pest prevention | Fire prevention and code compliance |
| Documentation | Cleaning logs | Certified service report and sticker |
The table makes the split obvious: different scope, different people, different reason. One keeps you clean, the other keeps you from burning down.
Where the two overlap, and where kitchens get it wrong
The two jobs meet at the hood, and that’s where owners trip.
The hood exterior and the baffle filters are everyday work. Your staff should pull and soak the filters on a schedule, and your cleaning crew wipes down the visible hood. That much is in scope for normal cleaning.
The moment you go past the filters, into the plenum, the ducts, and the fan, you’re in certified territory. That grease is out of sight and out of reach, and washing the filters does nothing for it.
The mistake is assuming a clean hood front means a clean exhaust system. It doesn’t. We map exactly where filter washing ends and the certified trade begins in our guide to cleaning hood filters and when to call the exhaust trade.
That’s the overlap from the opening. Clean filters and a wiped hood are not a cleaned exhaust system, and an inspector knows the difference.
How often each one happens
The two run on completely different clocks.
Everyday kitchen cleaning is daily and weekly, with a deeper professional clean on a recurring schedule, weekly, biweekly, or monthly depending on volume.
Hood and exhaust cleaning follows NFPA 96, which sets the frequency by how hard you cook:
- Monthly for solid fuel cooking (wood or charcoal)
- Quarterly for high volume cooking, like 24 hour kitchens, charbroiling, and wok stations
- Semiannually for moderate volume cooking
- Annually for low volume operations, like a seasonal spot or a church kitchen
Filters get washed far more often than the system gets certified. Think of the filters as a daily to weekly chore and the exhaust system as a scheduled fire safety service.
Why you need both
Skipping either one costs you, just in different ways.
Skip everyday cleaning and you get pests, bad reviews, and a health inspection problem, because grease and debris pile up where people can see and smell them.
Skip hood and exhaust cleaning and you get a fire hazard and a compliance failure. Grease inside the ducts is fuel, and a flare up on the cook line can run straight up into a loaded exhaust system, which is why grease buildup is a direct kitchen fire risk. Your insurance and your fire code both expect the certified service on schedule, with paperwork.
So the answer isn’t one or the other. It’s both, on their own schedules, from the right people. Excellence handles the everyday kitchen cleaning for restaurants across Northeast Pennsylvania, the surfaces, floors, and hood exterior, and we’ll tell you when your exhaust system is due so you can book your certified company. That division of labor is the same one we lay out for every job that sits at the edge of a cleaning contract.
Get both on a schedule and your kitchen is clean tonight and safe all year, which is the whole point of calling either one “cleaning.”
Frequently asked questions
Is hood cleaning the same as kitchen cleaning?
No. Kitchen cleaning covers surfaces, floors, equipment, and the hood exterior. Hood and exhaust cleaning is a certified job that degreases the inside of the exhaust system, the ducts, plenum, and rooftop fan, to meet fire code. They’re different scopes done by different people.
Can my staff clean the hood?
Your staff can and should clean the hood exterior and wash the baffle filters. They cannot clean the ductwork, plenum, or fan to code. That interior work requires an NFPA 96 certified exhaust cleaning company.
How often does a hood have to be cleaned by a certified company?
NFPA 96 sets it by cooking volume: monthly for solid fuel, quarterly for high volume cooking, semiannually for moderate volume, and annually for low volume kitchens.
Do I still need daily cleaning if I get the hood professionally cleaned?
Yes. Certified exhaust cleaning happens a few times a year at most and only cleans the exhaust system. It does nothing for tonight’s spills, floors, or surfaces, which is what everyday cleaning handles.
Who cleans the hood filters, my staff or a pro?
The baffle filters are everyday work, so your staff pulls and soaks them on a schedule, and your cleaning crew keeps the hood exterior clean. The certified company handles the grease past the filters that you can’t reach.
What happens if the exhaust system is not cleaned?
Grease builds up inside the ducts and fan and becomes fuel. A cook line flare up can ignite it and travel through the system, and skipping the certified service also fails your fire inspection and can void your insurance after a fire.
