Has anybody on the forum ever try using this stuff to polish a gun or gun parts? I have an old Victorianox Swiss Army knife and was bemoaning the fact that it's once shiny new stainless steel blades were looking kind of punk, when my wife said not to worry, that she used fingernail polish remover to polish our stainless steel kitchen knives, and that it worked wonders on them. (My first thought was to wonder how much residue from that stuff may have gotten into our food over the years, but she said she always washed them afterwards, and we're not dead yet so I guess it was ok.) Anyway, I tried her fingernail polish remover on my Victorianox blades and the stuff did work wonders. The blades looked like new. I'm scared to try it on my stainless steel gunparts like hammers and triggers though, because I don't know what it might do to blued parts if it got on them. Has anybody ever tried using the stuff on a gun or on gun parts, and if so, what were your results? Will it damage blueing?
