Coin Chaser Valued Member United States 307 Posts	Posted 12/09/2010 3:19 pm We just bought a lot of coins that are very sticky and greasy. Is there a safe way to clean them? Reading the posts they advise against cleaning but these coins are need to be cleaned. Thanks for any help. Report this Post to the Staff

Tim Stroud Pillar of the Community United States 2661 Posts	Posted 12/09/2010 3:40 pm An acetone soak should do it. About 10 minutes or so in the acetone and a rinse with distilled water and that should take care of the problem. You may need to repeat several times for heavy build up. Report this Post to the Staff
Coin Chaser Valued Member United States 307 Posts	Posted 12/09/2010 3:53 pm Thanks Tim. That will not effect coins? Some are copper, silver and nickel. Report this Post to the Staff
jbuck Moderator United States 189648 Posts	Posted 12/09/2010 4:09 pm Pure acetone is an organic solvent and should have no affect on the coin metal. You need to be very careful with it. Use only in a well ventilated area. Do not reuse it; always use a fresh quantity for each coin.

Coin Chaser Valued Member United States 307 Posts	Posted 12/09/2010 4:28 pm Wow! We have a lot of coins to clean. We just want to rid them of this sticky problem. I was hoping that we could clean several hundred at a time. Dipping rinsing and drying reusing the acetone. Report this Post to the Staff
jbuck Moderator United States 189648 Posts	Posted 12/09/2010 4:49 pm It does not take a lot of acetone for each coin, nor does it take a long time. I have never done so, but you may be able to do them in batches. Most of the ones with light contamination could be okay, but you may have to run some of the more heavily contaminated ones through again.

Numisnut Valued Member United States 123 Posts	Posted 12/10/2010 6:48 pm Start off with Dawn dish washing liquid first. It will remove the grease and get ready for anything else that's needed.5 gallon buckets would be good. Edited by Numisnut 12/10/2010 8:09 pm Report this Post to the Staff
