I bought some dry acid pickling salts from Chronos for cleaning up
stainless items after silver soldering. I appreciate that, even at
240gms/litre concentration, this is a pretty weak solution, but I'm
still a bit disappointed with the results - I had hoped that it would
remove the blackening as well as the flux, but it does not, even after
an extended dip. Would I be better off using sulphuric acid instead?

Cheers,
Paul
