I've just cleaned my silver rods in my ultra-sonic cleaner. The thing is,
they seemed to have turned white in places. The question is: will this be
a problem and what can have caused it? Bits are still silver and I
watched the black stuff come off in little clouds. I hope I haven't
ruined them as this is my last pair! dee
