The Industry Behind Every Commercial Kitchen in America
Every restaurant, hotel, school, hospital, and food service facility is legally required to have their kitchen exhaust systems professionally cleaned. Here's everything you need to know about the industry you're about to enter.
What Exactly Is Kitchen Exhaust Cleaning?
Commercial kitchen exhaust cleaning — also called hood cleaning — is the professional removal of grease and residue from the entire exhaust system above a commercial cooking range. This includes the hood filters, the plenum, the ductwork, and the rooftop exhaust fan.
Grease buildup is one of the leading causes of commercial kitchen fires in the United States. Regular professional cleaning keeps restaurants safe, keeps insurance valid, and keeps the fire marshal satisfied. That's why it's legally required.
The Transformation Speaks for Itself
A professionally cleaned kitchen exhaust system removes 100% of the grease buildup that accumulates from daily cooking. The transformation is dramatic, visible, and immediately satisfying to clients who can see the difference with their own eyes.
This is why hood cleaning has virtually zero churn — once a restaurant owner sees what you do, they put you on a recurring schedule and keep you for years.
Why Every Commercial Kitchen Needs This Service
NFPA 96 — the National Fire Protection Association standard for commercial cooking operations — mandates regular inspection and cleaning of kitchen exhaust systems. The frequency depends on how heavily the kitchen is used.
