<p>[QUOTE="Ken Dorney, post: 2380601, member: 76086"]I'd never head of VerdiCare before. I googled it and came up with vague descriptions and explanations. "proprietary' this and that. Dont know what it is really or how it reacts. Maybe perfectly safe but in my 30+ years I have never heard of it. But then, I dont typically clean coins. Although some will say one should never clean by any mechanical methods, with bronze disease it has to be removed physically. With Greg's coin I think it could easily be saved. Use water and a wooden toothpick. Dig out the areas of issue. When you get to bare metal (as far as you can see) wash again with water. Dry it out thoroughly (some will place into an oven at low heat, I suppose direct sunlight will suffice). When you think you are done, go again. After your final treatment, let the coin sit for at least six months to see if it comes back. After a year or more if it doesnt come back one can treat with sealants, such as Renaissance Wax or Dellers Darkener. Using the above methods, I have never seen it come back.[/QUOTE]</p><p><br /></p>
