<p>[QUOTE="Boss, post: 500999, member: 15110"]Look up the product "Verdigone" on Collectors Society. It is a good product for this type of problem. "Bad Thad" sells it and he is a chemist. You could soak in olive oil for a short period (be careful it goes rancid), and then switch to mineral oil but this could take a year. Doug has suggesstion Biox from the website "dirtyoldcoins.com", but I haven't tried it. Acetone will help a little, but that verdigris is pretty thick. Hot water is better if distilled (I personally would never use tap water). You'd be suprised what distilled water soak for a long time (weeks) would do. Let us know what you do and post after photos. I am very curious what you try. Good luck[/QUOTE]</p><p><br /></p>
