There is also a topic here on the forums in which a member describes their use of a product to refurbish the original, brushed stove surface. Nope, I'm not going to give you the link. Use the message search for it. Awww... Everything in life is not handed to us on a silver platter. The same goes here.
Let's see who can find it or who will even try. Whoever does, and finds it, post the link to this topic. The first member who does and it is the correct one, will be rewarded with a gift from the Phåråoh's treasure trove!
