What's the other 1%? Good question. Pour some in a clean glass bowl. Let it evaporate. If there is anything left behind then you know not to use it. |

Water is a powerful solvent in it's own right.
Most INorganic sulfate, nitrate, acetate, halide, and ammonium salts are soluble in water,
as well as the fact that a huge range of ORGANIC compounds are soluble in acetone.

Perfectly safe for everyday indoor use in small amounts. Not noxious as such. This is not gasoline.

acetone is a component in fingernail polish remover. nail salons use lots of it. Just don't use near flame and use in a well ventilated area. seal up tight after use. I get pure acetone at Walmart in the beauty dept. |

 Don't know if where your at you can buy pure Acetone but it does not effect metal so safe with coins. |

acetone is a component in fingernail polish remover. True, but it's not 99%. There are other additives that can harm coins. Don't use fingernail polish remover. |

Finger nail polish remover is not pure 100% Acetone . It contains other ingredients such as perfume & water .It is highly recommended NOT to use it on your coins . Quote:

Agree , and most of us do use it indoors with caution . but for newbies who are just starting out to use this product it would make them realize not to use it carelessly , like soaking your coins on the dinning room table with a cigarette hanging out of your mouth .   |

Yes. This is one product to use to (try to) clean organic residues off of coins. For reasons pointed out by others, after you soak the coin in acetone, rinse it off immediately with distilled water.
As pointed out by @lionel, acetone vapors are highly flammable, so you must not use it where there is a lit cigarette, or in a kitchen, or anywhere else there may be a small flame (pilot light).
Good luck and Happy New Year.

I dip almost all my silver coins in pure acetone before sending off the NGC or PCGS. I've never had any problems with it.

Check your local paint store, like a Pittsburg Paint or Sherwin Williams store, They will carry acetone, especially if they make custom stains or dyes.

I use these brands with good results. The old bottle makes a good storage container for used acetone until I can dispose of it.  |

Possibly a McDonalds but not to many paint stores with those names. Be careful of what people may say is in the ones you buy. Do a simple test before using. Take a really clean glass dish and pour some into it. Allow it to evaporate. If there is absolutely anything left on the dish, the Acetone is contaminated with something. Do not use on coins. |

I buy it at a local big box home repair store. In gallon tin cans. 100% acetone and it's much cheaper than little bottles of nail polish remover. Just close up the lid tight when not using and it will stay good for years. I pour a little in a small glass bowl and will soak any dirty grimy coins in it. It will not harm metal. Absolute necessity for treating any coins that have been stored in old vinyl. Gets rid of that green slime in no time. Also works on the tar type substance you sometimes see. But it take a longer soak. Also, sometimes removing the tar spots reveals untoned metal and that can make the coin look splotchy.
Since acetone evaporates so fast it won't leave spots. And you don't have to risk blotting a coin dry like you do with distilled water.
I always hesitate to use in on copper coins though. Not that it hurts the copper. But for some reason, removing all the oils make the copper look dull to me. Of course if there's green stuff on the copper, I still use the acetone.
