I recently found a mint Bluetip with case. I cleaned it up and put it away, Today I noticed 3 small dots of oxidation on the collar. I got them off with flitz and q-tips. How can I protect this to prevent oxidation? I've never even used it and now I'm afraid to because its so gorgeous as it is. I don't want to ruin it. I have a beater I can use. I was thinking a coat of mineral oil?
