I have never tried using acetone to remove gunk from coins before so I went out and got some the other day and tried it out this morning. It does not seem to have done anything at all to the three coins I tried it on. All I managed to do was stain my fingers blue from the screwdriver I touched when there was still acetone on my hands when cleaning up the work area. What I did was pour about 1/4" of the stuff in the bottom of an old coffee cup and then place the coin in there. Put something over the top. swirl it around a little for 15 sec or so, flip the coin over and repeat. Then rinse the coin. All to no effect. Any suggestions?

Acetone will not remove anything except organics, like finger grease or PVC. It has no affect on corrision, verdigris, or staining that is in the surface of the coin. I always give my circulated silver coins a dip in acetone before placing them in a Dansco album. I wouldn't expose my skin to acetone very often if I were you.

I'm not sure if you are leaving the coins in the acetone long enough. I usually put them in a covered glass jar with the acetone overnight. Saying that, acetone works better for some coins than others depending on what the problem is.

In my opinion, I see many people handle coins Many different ways, some touch all over, some do not, point being, the practice of giving all circulated coins a soak in acetone and rinse afterwards of distilled water and a 'patting" down before placing said coin(s) in an album, I believe is a great start at preventing some organic matter( seen or unseen ) from altering the coins in the future.....Also, it does do better of a job removing matter from some coins than others....

Suggestions are as follows:
1. use the SEARCH tab at the top of the page for Acetone or cleaning coins or coin cleaning and/or any other similar types of posts.
2. As noted Acetone does not make coins new. In fact it does very little.
3. If you do use it and don't rinse the residue from the Acetone with distilled water the evaporation might leave some odd stuff on your coin. Note many use tap water.
4. If your Acetone was not pure enough, it could end up doing more damage than good.
5. Sounds like you used your fingers to flip the coin. Ever think of what may be on your fingers?

I usualy clean my coins of gunk and organic materials before stapling them in flips. First is pencil rubber eraser whihc removes the gunk, then soft cotton cloth for the little pieces of eraser left over, then ethyl alcohol for disinfectant of organics, dry pat and staple in flips. have never used acetone as it is 10x more expensive than 70%ethyl alcohol as disinfectant  |

Organics? Acetone did a great job on several of my paint brushes which I'd cleaned poorly and left some polyurethane varnish on so that the bristles stuck together.

Advantage of buying brushes at the flea markets. Much cheaper and safer than Acetone. As to Acetone on your skin, try the ATSDR web site. That is the Agency for Toxic Substances and Disease Registry. A pencil eraser? Guess those coins are shot. |
