hello all, I sometimes get a pinkish tint on yellow gold after an
extensive soldering job. (tipping multiple tips ect…) It doesn’t
appear on the outside of the piece. It’s on the underside and in
hard to reach areas. No matter how long I pickle or try to polish
those areas, I’m still not satisfied. Let me say that I have never
had a customer complain, its just something that bothers me. Thanks
for any suggestions.
