I've been using this pan for a while, and have somehow scorched the bottom of the pan. Can someone tell me how I should clean it? Thanks!
The discoloration is from overheating the pan, not from stains. The actual metal has changed color through accidental tempering, so you won't be able to clean it off other than by grinding the metal down or re-tempering it (neither of which is a good idea).
The color won't significantly affect the performance of the pan. Just ignore it.
