Tin Stripping from Silver: Safe, Smart Stripper Advice

Summary for tin stripping from silver Discussion

Tin stripping from silver is the central issue in this thread, with the original question asking for a way to remove tin plating from silver without discoloring or stripping the silver. Louis Hirbour’s supplier note mentions a solution-based process using sodium chlorite as the oxidant, but warns that its effect on silver is uncertain and should be watched closely. Years later, Kate Fowler asked specifically for a tin backstrip for silver-plated electrical contacts, where selective tin plating can bleed onto adjacent areas and flash tin must be removed without harming the silver finish. David replied that an MSA-based immersion tin stripper may be suitable because it should not attack silver. The discussion is brief and somewhat cautious, but the practical takeaway is to use a silver-safe tin stripper and verify compatibility on the actual parts before full-scale use.
