A commercial kitchen hood does more than pull smoke out of the room. It captures airborne grease that condenses on every surface downstream of the cooking line: the filters, the plenum chamber behind them, the ductwork, and the rooftop fan. When that grease is left in place, it narrows airflow, drips back toward the cooking surface, and becomes fuel if a flare-up ever reaches the exhaust system.
Tennessee Hood Cleaners cleans the entire exhaust path, not just the visible stainless steel canopy. Our crews scrape, degrease, and pressure wash each accessible component, then document what was cleaned so owners, managers, and inspectors have a clear record of the service.

Safety and NFPA 96
For commercial hood cleaning, NFPA 96 (the National Fire Protection Association standard for commercial cooking operations) is the usual reference for inspection, cleaning access, and documentation. The edition in force and how it is enforced depend on your local authority having jurisdiction. We clean thoroughly and document our work, but no contractor can guarantee an inspection result. Learn more about NFPA 96.
