Hi all, I do contract work silver soldering nickel silver. I read in
Orchid about pickeling with sparex and hydrogen peroxide, so I gave
it a try. It works great; the pieces come out really clean and
bright, however, after I rinse them with plain water, they start to
tarnish immediately! By the time I turn them in, maybe only an hour
later, they look like they’ve been sitting around tarnishing for a
couple years. I suspect it may have something to to with the oxygen
in the peroxide clinging to the metal. Is there something I should
rinse them with to prevent this? I tried baking soda, with no result.
Any suggestions would be appreciated.
