How do I clean a metal extractor fan filter?
Aluminium FilterPurchase some sudsy ammonia from your local supermarket. If your metal extractor fan is made of aluminium, or if you do not have a dishwasher, remove the cover of the extractor fan filter. Wash it in hot soapy water in the sink. Remove the blades of the extractor fan and the metal mesh filters, place them in the sink, and wash them with the sudsy ammonia solution. Dishwasher detergent damages aluminium, so do not place aluminum filters in the dishwasher.Stainless SteelPlace the steel extractor fan blades and the mesh filters in the dishwasher on a hot cycle (about 70 degrees F) to thoroughly remove dirt and grease.
