Building a Kitchen Hood Cleaning Schedule That Holds

Wiping hood exteriors, emptying grease cups and clearing the cooking line reduces the amount of vapor that reaches the filters in the first place.

Five minutes a night meaningfully slows accumulation in the plenum.

Baffle filters should be pulled and run through the dish machine or soaked weekly in most kitchens, more often on fryer-heavy lines.

Filters must go back in the correct orientation or they stop capturing grease entirely.

Look for grease past the filters in the plenum, verify the exhaust fan is running at normal speed, and check that make-up air is not being starved.

Anything visible past the filter line means the professional interval may be too long.

The scheduled service covers hood, plenum, full duct run and the rooftop fan, which no in-house crew can safely reach.

Booking it on a fixed recurring date is the only way it reliably happens during a busy season.
