Your extractor hood clears the air of smoke and grease from everyday cooking but this will eventually result in a build up of residue. Over time, grease will build up and clog your extractor hood filters and leave your hood looking shabby. For heavy grease deposits carefully use a plastic scraper initially to remove the majority of the residue. To complete the clean of your hood use a de-greasing product in hot water to remove the remaining greasy deposit before wiping off and buffing with a clean cloth.
For stainless steel hoods, finish by polishing with a dry microfibre cloth moving in the direction of the grain.
