Artemis737 New Member Slovenia 31 Posts	Posted 08/18/2023 08:25 am Happy to report that the pure acetone lifted most of the foam from the surface of the medals. Which solution would you recommend for medallions with a potential lacquer finish and with a foam residue on the surface? Will Goo Gone and distilled water afterwards work in this case?

HondoB Bedrock of the Community United States 25509 Posts	Posted 08/19/2023 11:55 pm Artemis737, I'm happy to hear that acetone has resolved most of the issue. But Goo Gone? That would not be my next step, because I have no idea what is in that stuff. Work your way up the solvent ladder.

Artemis737 New Member Slovenia 31 Posts	Posted 08/20/2023 12:05 pm It was observed by others that the base metal medallions seem to be covered with a thin coat of clear lacquer. They were made like that and I don't want to touch, alter the surface and/or remove the lacquer finish. The foam particles are stuck to the surface, acetone would probably quickly remove them, but would probably dissolve the lacquer finish in the process as well. Distilled water may not be able to remove much, that's why I mentioned Goo Gone and subsequent distilled water bath as a potential alternative. The ingredients in Goo Gone are Adhesive Remover include petroleum distillates (hydrocarbon) PPG-3 METHYL ETHER, KEROSENE (PETROLEUM), HYDROTREATED solvents, limonene (hydrocarbon), and orange sweet extract. The particles could potentially be removed mechanically by a Q-tip/distilled water rinsing too... Edited by Artemis737 08/20/2023 12:46 pm Report this Post to the Staff

I kinda figured that it might remove lacquer, since it seems to be a rather aggressive treatment. Report this Post to the Staff

jbuck Moderator United States 189340 Posts	Posted 08/21/2023 10:04 am Professional conservation is probably the correct move. Coin Collector Since 1978 Avatar Old Avatar 7070 Eisenhower Australia Canada World CCF Members on eBay CCF eBay Search Engine Report this Post to the Staff
