Ceramic Hob Cleaning Kit 5 "Great Product" Margaret SHONE 18 March 2013 I have been using this product for years. It works brilliantly. I stock up on replacement blades to save on postage costs and every couple of years I buy a whole new kit. I have used it on all sorts of surfaces it doesn't scratch and gets most debris off without much hassle! It is easy to take apart to scrub the plastic outer clean as well. I love it.
