Hood and Plenum Cleaning for commercial kitchens

Plan the job around the commercial kitchen

The plenum is behind the filters

Grease can collect in the chamber and transition area out of normal view. Removing filters is necessary to evaluate and clean it.

Visible stainless is only the beginning

Polishing the canopy does not address grease deeper in the collection area or connected duct.

Filter channels and edges

Grease can collect around filter tracks, seams, light housings and transitions.

Connect the scope to the duct

The proposal should explain where hood and plenum work ends and grease duct cleaning begins.

Signs it may be time to request service

Grease running from filter channels
Dark deposits at the duct opening
Exterior wipe-downs do not remove odor

Are filters removed during service?

They generally must be removed to access the filter bank and plenum area.
