Oven Mate's mesh filter cleaner effectively removes sticky residues that accumulate in your cooker hood's metal filters. Regular use, ideally every month, ensures the extractor fan works properly and will help remove food odours and improve the overall performance of the cooker hood. To use, remove the mesh filters from the cooker hood and place in the sink. Spray both sides evenly with the Oven Mate mesh filter cleaner - the bright colour marker foam makes it easy to see any areas you might have missed. Leave for approximately 15 minutes, then rinse the meshes out under the hot tap to flush away the dissolved grease and dirt. Dry filters thoroughly before replacing in the cooker hood.
