Sticky aluminum half sheet pans - Self cleaning oven - What would happen? I recently cleaned my broiler pan with great success in my self-cleaning oven. Great. Now I'm looking at my aluminum half-sheet pans. They're sticky, they're discolored, I only have so much elbow grease to spare. I'm soaking the pans now to apply precious elbow grease in the morning, but I just don't want to. What if I ran the self-cleaning cycle again, this time with the cheap aluminum sheet pans? (They are of the "hotel" variety, not the disposable kind) I know they'd get clean, sort of, but would it ruin the pans?

This is pretty close to what I have (or what I used to have before I loaned them out): pans
I'd be mighty cautious about putting aluminum pans in your oven's self-cleaning cycle. It's melting point is 660 degrees C, and although your oven isn't going to reach that it will probably get to the point where they will warp.
