The hood clears the air of smoke and grease from everyday cooking, but they can leave their mark. Over time, stains can build up and vents can clog. Clean the exterior of the hood weekly and the filters monthly.
Using a soft cloth dipped in hot, soapy water (dishwashing liquid is fine), clean the hood; wipe off with a clean damp cloth.
Remove filters and place in hot water with dishwashing liquid for five to 10 minutes.
Brush with a nylon scrub brush. Rinse in hot water, and dry. Some filters can be washed in the dishwasher; consult your stove's instruction manual. Maier nonstick pan-cleaning brush (similar to shown), from williams-sonoma.com.
