Wow - what FANTASTIC stuff! Although this paste had rescued a well-used, slightly yellow toilet seat before and brought it up like new (and brilliantly white!), I had not thought of using it on my large stainless steel extractor fan before. After all the Christmas cooking excesses, though, it really needed a clean and the build-up of fat shifting - and the Astonish paste came up trumps, where so many other cleaners have failed. It shifted virtually effortlessly, in combination with a micro-fibre cloth, the caked-on grease, and my cooker-hood is shiny and looks like brand-new again! Highly recommended!!!
