The trick to cleaning silver is not just to remove (not so good) or
reduce back to metal (better) the silver sulfide tarnish. The trick is
to keep it from re-tarnishing!
Treating the newly cleaned surface with a fractional percentage in
solvent of benzotriazole adsorbs a monolayer with extraordinary tenacity
and provides prolonged protection against re-tarnishing. Works on
copper, too (nice FTIR/ATR experiment - you can see the bonding.)
