Message-ID: Date: 14 Feb 91 18:12:05 GMT Sender: news@cs.psu.edu (Usenet) Distribution: na Organization: Random, at best Lines: 11 Nntp-Posting-Host: psuvax1.cs.psu.edu Hi. Me again, still reconditioning carbide lamps. Does anybody know of a good way to remove excess solder from a joint on copper or brass, other than massive polishing? i.e. is there an acid or catalyst that will remove solder without bothering brass? I usually remove all the molten solder I can with a wire brush, but that leaves the area solder-plated. I can polish it off, but polishing removes more brass than I'd like. (Stamped-in lettering completely disappeared by the time the solder was gone.)
