Grease on a range hood collects mainly on the underside, housing, and metal filters. Regular cleaning prevents sticky layers and keeps airflow open without soaking the motor, wiring, or controls.
Turn the hood off and let the area cool
Work with the cooktop cool and disconnect the hood if the manual calls for it. Remove loose dust and surface grease first so you do not push grime into slots or electrical components.
Separate metal filters from charcoal filters
Many metal grease filters can be washed with hot water and mild degreasing detergent, while charcoal filters are usually replaceable and do not regain performance through washing. Follow the model manual.
Degrease the housing without flooding seams
Apply cleaner to a cloth rather than spraying buttons, lights, or seams. Let it dwell briefly on hardened grease and use repeated wipes instead of abrasive pads that can scratch stainless steel or paint.
Reassemble only when everything is dry
Washable filters should be completely dry before reinstalling them. If airflow remains weak or the fan vibrates after accessible surfaces and filters are clean, internal service may be needed.
