bakeware turned black!
I just got a new kitchen (dw, conv oven, etc) and now my baking sheets are covered with a gray coating. It rubs off on my hands, but doesn't come off when I scrub it. First question, which appliance caused it? I'm assuming DW, but not sure. Second, how do I get rid of it? Third, what type of bakeware should I buy to avoid it?
