Second Investigate how museums clean and preserve copper and bronze objects for display purposes. Several methods can be found. Experiment on some other bronze or copper object for safety and efficacy, then choose one of those methods for your coin. Report this Post to the Staff

Seeker55 Pillar of the Community United States 635 Posts	Posted 06/10/2020 11:58 am If either of you wishes to remove the greenish material (called "bronze disease") you could try soaking in sodium sesquicarbonate solution for a few days up to a few weeks. Formula for sodium sesquicarbonate solution: 10.6g of sodium carbonate (washing soda) and 8.4g of sodium bicarbonate (baking soda) dissolved in 100ml of distilled water.
