  • I have several bronze medals with various amounts of verdigris.  I've tried a few cleaning solutions to no avail.  Note I am a long-time coin collector and won't be doing any mechanical cleaning (brushing).

    Anyone know of a chemical that can neutralize and maybe reduce the green effect?  I've tried researching online but found many references to chemicals no longer available.
