Hey, so I recently found a good deal on a Whirlpool ceramic cooktop, which is now sitting in my kitchen in place of the 30 (possibly 40) year old ancient range that was there before. Anyone have one of these? I've read about problems with aluminum cookware leaving marks on the cooktop, how big of a problem is that? I have a combo of aluminum, anodized aluminum, stainless and cast iron cookware. Otherwise it looks pretty cool and works a lot better than the old coil range i had before. I also got some of the Cerama Bryte cleaner, works pretty well! I think it is just glass polish, wondering if I can use it on my windshield?
