Yes, I tried a mix for chemically stripping tin and lead from copper. I
think it also removed the inter-metallic layer between them, which is
important, judging by the bright copper colour, but that's a guess. I can't
find the details now, but if you Google enough you'll probably find the
details at a site specialising in advising members of the metal plating
industry. I think it was a mixture of water, copper sulphate and sulphuric
acid (which I had to hand) and used at about 80C. There were some other
formulations but they sounded more complex or expensive and commercial
products are available if cost is no object. I haven't checked the result
for thermally generated voltage against the same lugs with the plating
thoroughly sanded off, but they looked the right colour.
