Foiled Burned on Glass Stovetop BurnerI have a smooth glass top stove. I put a peice of aluminum foil on the hot burner. It only was on the glass for a moment. When I removed it, some of the foil melted into the glass. It is not "a lump of foil" that can be easily scapped off with a razor. It actually seems that the foil melted into the glass. I have tried using vinager, salt, oven cleaner,oxiClean, lemon, and baking soda paste. Any other ideas out there?
