Friends,
I forgot about a few silver
denarii and one silver
shekel that I put in
PVC holders 30 years ago! They are green as can be and have a greasy feel to them. Yikes!
What is the current recommendation for removing
PVC damage these days? I have heard that acetone is the usual course but I have heard other recommendations also.
Should I:
(1) Let them sit in a bath of acetone for 15 minutes; or
(2) Let them sit in a bath of rubbing alcohol for 15 minutes; or
(3) Let them sit in a bath of soap and water for 15 minutes;
And, in any of the above situations, should I use a Q-tip to "whirl around" in areas where the green doesn't come off?
Lastly, in one of the silver coins, black (very very dark) spots appeared on one
side of the coin instead of the usual green. Could
PVC cause that as well?
Thanks!
