Turn the hood off and let the cooking area cool. Separate washable parts from electrical parts: the housing, filters, motor, and controls do not get the same treatment.
Start with the exterior and underside
Remove dust, then grease using a cleaner compatible with stainless steel, paint, or glass. Apply cleaner to the cloth near switches, lights, and seams instead of spraying into openings.
Identify the filter
Metal mesh grease filters are often washable. Many charcoal filters in recirculating hoods are consumable and must be replaced. Check the manual before putting any filter in a dishwasher.
Degrease a metal filter gradually
Soak it in hot water with a compatible detergent and brush gently. For heavy buildup, repeat rather than combining aggressive chemicals.
Do not spray the motor or electrical cavity
Visible grease near the fan does not make internal soaking safe. Deep buildup that the manual does not make accessible is a service-level cleaning task.
Dry completely before reinstalling
A wet filter carries moisture and residue back into the hood. Reinstall it securely and confirm normal airflow afterward.
Cleaning before the filter becomes saturated keeps grease from migrating deeper and helps the hood move air effectively.
