rtropp Posted February 5, 2015 #1 Posted February 5, 2015 I have read about pickling in silver soldering. I will be soldering copper wire and copper parts. I was hoping for some opinions on those who do or do not pickle. I thought that pickling was to remove burn off in the finished piece but now am not so sure. One member said they pickle before soldering and after. I would appreciate any ideas. Richard Quote RichardMember: The Nautical Research Guild Atlanta Model Shipwrights Current build: Syren
yamsterman Posted February 5, 2015 #2 Posted February 5, 2015 Hi Richard I used to use jewelers pickle,10% hydrochloric acid,if I remember rightly to clean up parts, brass and copper after soldering. I tend to use ordinary domestic malt vinegar now.....its still a 10% acid solution and does the same job.seemsto work.....no problems up to yet! Prior to soldering I would use iospropanol,acetone or even good old m.e.kto clean the parts.make sure you wash it of before soldering! Clean the areas to be soldered with a scratch brush and away you go. Cheers......mick Quote

Jaxboat Posted February 5, 2015 #4 Posted February 5, 2015 (edited) Wow! There is an enormous difference in acidity between a 10% solution of acetic acid (vinegar) and 10% HCL. If the vinegar works, then I would stick with it. Much safer. Flux is also weakly acidic. If often is composed of Rosin acids, a by product from Pine Tree pulping.
