Oven Mate Oven Hood Mesh Filter Cleaner 500ml 5 "Brilliant" Mrs Swan 16 February 2021 I was a bit sceptical about how good this product would be but I just went for it. I'm so pleased I did, it is amazing stuff. It cut through 14 years of yucky grease on the fan that is tucked away behind the scenes. With our extractor not working effectively I didn't really have a great deal to lose. I also sprayed the product on the metal housing and, having left it a good long while the grease came away with minimal effort. I used a whole bottle getting the entire unit clean (avoiding the motor) but it was well worth every penny to get it working again rather than buying a new extractor.
