Bronze Disease/Verdegris Treatment Help

Verdigris is not synonmyous with BD. BD is caused by propagating chloride ions eating into the copper whereas verdigris is oxides forming on the surface.

For BD, whichi s light green and powdery and can be removed easily with a nail, you need to remove the ions. The easiest and safest way is to soak it in distille dwater - the ions will go from the coin to the water. You'll reach an equilibrium pretty quickly so you have to change the water daily. Remove any green powder that develops without remorse - blitzkrieg is the only method that will save severely riddled coins. It could take a while until you get to a good stage, no less than 2 weeks.

For Verdigris, definitely wash in acetone, but also try using BadThad's Verdicare. The stuff might work for BD too, who knows.

Refer back to Ben Byfield's answer regarding BD. Verdigris should really have that chemical intervention of Verdicare. Acetone likely won't do much for it.

Verdigris and bronze disease can be a major problem for ancient coins, retrieved from ground burial.
Ancient coins are often found in hoards and attract the attention of museums. One of the benefits for the coin is that they can then be cleaned by professionals, who also take action to preserve them as part of the cleaning process.

In order to to kill off the threat of bronze disease, take some time to find out how it is done. Have a good search on this subject on the internet.
