Your going to think I am crazy but a friend of mine just said the other day that he had a pair of Cardas Quadlink 5c's that had oxidation on them and he used toothpaste on them and it took it all off. They look like brand new?? I Tried it myself and it worked?? They look new? Give it a try it's not going to hurt anything. Good luck. let us know.
Here is a link to a thread here some time ago on the same thing.
The person who asked the same question tried the tooth paste and said it worked for him also. there are also some other godd suggestions there. Good luck let us know.
