Frequently asked questions about Hood & Duct Cleaning

How often must a commercial kitchen exhaust system be cleaned?
NFPA 96 sets the interval by cooking volume/type: monthly for solid-fuel cooking, quarterly for high-volume operations (24-hour, charbroiling, wok cooking), semi-annually for moderate-volume (seasonal/institutional) kitchens, and annually for low-volume operations such as churches or seasonal businesses.
What does "cleaned to bare metal" mean?
NFPA 96 requires the hood, grease-removal devices, fans, ducts and other appurtenances to have all grease removed down to the bare metal surface — not coated over — before contamination becomes heavy; parts that cannot be restored to bare metal must be replaced.
