Degrease commercial kitchen hood filters
With the cooking off and the filters cool, lift the baffle filters out, soak and scrub off the grease, and put them back the right way. The fire suppression system is never touched.

Turn off the cooking equipment and the hood fan, and let the filters cool.
Wear gloves and eye protection: the filters are heavy, sharp-edged and greasy.The nozzles, pipes and small metal links over the cooking are the fire suppression system. Don't touch, wipe, bend or hang anything on them.
Lift each filter up, swing its bottom out of the channel, and lower it out.
Soak them in hot water with a kitchen degreaser, as its label says, then scrub with a soft brush. Your dish machine may do it if the filter maker allows.
Never mix cleaners.Empty and wipe the grease cup or trough at the end of the hood.
Rinse and dry them, then set them back in with their baffles running up and down, every slot filled.
Never cook with a filter missing: grease gets into the duct.A bent or torn filter, grease dripping from the hood, or a nozzle knocked or caked in grease: don't cook under it. Call the hood cleaning or fire suppression company.
