Are they easy to remove from clad? If removed does it leave a mark? Thank You.

Dipping in acetone and rinsing with distilled water works well with silver. I am not sure about clad coins.

Verdigris and PVC are different are they not?

I was told Verdigris is pretty common on copper coins and comes in active and non active forms.

PVC hits silver and is always detrimental.
