I have a couple of tin-lined copper pans. I've been away for a year, and they've been unused. After a basic washing (and polishing the copper), I find that the tin has a lot of discolorations -- spots, dots, dark patches, etc.
What is this? Should I worry about it? How do I get rid of it, or do I need to?
Thanks....
