I was curious about cleaning the wort chiller also, glad I found this thread. Soaking the wort chiller in a star stan solution for just a few minutes cleaned that copper right up! Nice too because I don't have to scrub anything.
I received a copper wort chiller recently from a friend, this was a really helpful page! Thanks everyone!
