I've used acetone on a few occasions to remove paint on colorized coins. After the paint had dissolved I just rinse in cold water and pat dry on a soft cloth. Works good for me, no left over residue.

I use distilled water but I suppose regular water would work as well. I use the former because I have it around for drinking and figured that I had better be safe than sorry.

Acetone, distilled water, then a final acetone rinse. No blow dryer needed, as long as you are doing this at normal room temp (72-78F) the acetone will flash off quickly.
BTW, you might want to use another word besides "dip"- that generally denotes dipping in a substance such as E-Z-EST or similar coin cleaners.

Why the finial acetone rinse? Isn't the purpose of the distilled water to get rid of the acetone? quote:

Opps, didn't know. Changed the title, hopefully it's clearer. |

The purpose of the distilled water is to remove the stuff the acetone took off.
The purpose of the second acetone is to remove the water.

Amazon,
To further clarify:
when I am soaking a batch of coins in acetone, I set it up assembly line style. My first acetone bath does not get changed to conserve the acetone. Yes, it accumulates gunk but it is still effective at removing organics as well. Normally, this would leave a coin contaminated but then I bathe with distilled water(in my case, reverse osmosis purified, not distilled but most do not have access to RO water) to remove any further contaminants. Finally, another clean acetone bath to remove the water.
If I only need to soak one coin, it will go into the acetone and that is it- no water. The water is not necessary to remove the acetone as acetone is a VOC(volatile organic chemical) so it will readily flash off leaving no trace provided that it is pure. If you rinse with water afterwards you run the risk of leaving water spots, even with distilled water.

I use a small space heater to make sure they are dry. But my final step is always to hit the coin with compressed air. Blow dryers and space heaters are still taking in air from the room that may have dust in it and I don't know how well the dust filters in these things work or if they even have filters.

Make much more sense now, thanks. |

How long do you have to soak a moderately stained silver dollar to get all of the gunk off?

I have very, very rarely "soaked" in acetone. I normally just hold the coin (with rubber gloves) and rinse to remove any trace of water. My theory is no water, no air, no corrosion. I just ordered 100 airtites to preserve my Lincoln collection.  |

This thread got me intrigued about the possibilities provided by acetone, so while at my friendly Wal-mart yesterday, I picked up a bottle (from the finger-nail polish section, not the aisle with tape and bandages, which is where I looked first). Then as I was checking out, I got carded. Apparently you have to be 18 to buy acetone. What is that about?  Jan |

AHHH so many stories about Acetone. I've been using it for many years but usually a chemical supply house version. Do not use nail polish. Note the lable, it contains all kinds of stuff and some are perfumed so your coins will smell nice. If you use Acetone for coins it will disolve some of the junk on the coins and will stay in solution until it evaporates and that would be back on the coins. I use the Acetone, rinse with distilled water, blow dry wit hair dryer on warm setting. No possible nothing from a decent distilled water. If your distilled water leaves a spot, something is wrong. Tap water may or may not be OK depending on where your live. In most areas the water is treated with Cl or Fl or both. Not good for coins. Also, if your water goes through a water softener, not good for coins or plants.
