Hi all, I had a very nice weekend, two of the days had over 100 clads each day, plus all kinds of other goodies. I tried the white vinegar I've seen recommended on here by some. I put the coins in a jug, poured white vinegar over them, let it sit 24 hours. Rinsed them in water. It got the dirt/grime off them, but turned them a green color. I did find a 64 rosey that was really dirty, but clearly silver after the vinegar step. Did I let the coins sit long enough in the vinegar? Should I do something else? I've seen that some people use baking soda, though I don't know how to mix it up. Any advice would be greatly appreciated, thanks!
