Stripping chrome in an electrolytic bath

Aug 21, 2008 · arm that I needed stripping, and I got similar answers, that a plating shop would be the best bet as chrome plating, and the reverse electrolysis to remove it, would be rather hazardous. I was directed to a site similar to this called Caswell Plating, as I wanted to buy one of their chrome plating kits for my swinging arm, once I''d had it stripped.
