Hi, hope this video helps you
Take the screen off and spray with a degreaser then soak in very hot water then wipe the whole bottom out
Healthy dose of Dawn liquid in your laundry tub with very hot water. Submerge your hood vent screens for a few hours, rotating if needed, due to space restrictions.
Rinse in hot water, scrubbing lightly with a soft bristle brush. Dry completely before re-inserting into your hood. Doing this after every 30 hours of vent use keeps the job more manageable.
