Obviously, standard advice applies here- test in a hidden area before
using anything in the final project!

Just to clarify that a bit more, I was under the impression that the
damage to the plating could be over a period of time. Testing may not be
long enough unless you let the test go for a year or 2.

Perhaps a piece of mirror with several possible compounds used for a long

it doesn't take that long. acids used for soldering mirror into stained
glass items can destroy the edges in just a few days.
