I was gifted a really lovely hard-anodized skillet last holiday. I have a cooking-averse roommate who uses it to boil chicken. Recently I pulled it off the pot rack, only to find that it had been hanging there for a few days with a gummy film of cooking oil on it. There's no way I put my own pot away like that! The problem is that soap is not getting it off. It's covered inside and out with a brown film. How do I get my pan to shine like the top of the Chrysler building? The pan is only 6 months old, how can I keep it looking like new?
