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.
