Acetone will leave a residue. For a residue free finish try this. Rinse the coin in acetone - remove it wet and then rinse it in methanol - remove it wet and rinse it in isopropyl alcohol - remove it wet and rinse it in distilled (de-ionized if possible) water and dry. Use a brush to remove any stubborn debris.

Use a brush to remove any stubborn debris. And naturally you should use a wire brush on a bench grinder set up.  Just kidding. Never use a brush at all. |

Acetone will leave a residue. No. That is not correct unless you haven't gotten all the residue off the coin yet and some is still suspended in the acetone. Acetone evaporates without a detectable trace, and that is fact, not subject to opinion or speculation. |

Rinse and repeat.   |

I hope that post by Eric was an attempt at humour.

You might want to check acetone use with some of the more unusual coining materials.
Gold, silver and copper seem inert to acetone.
I don't know about zinc, iron nor aluminum.
And using it on anything non-metallic should be strictly avoided.

Use a brush to remove any stubborn debris. And then in Paint thinner, then Laquer thinner, then in Sulfuric Acid. NOW for sure all dirt is gone. |

It gets grease and dirt off of coins. I have used it. It will not make a silk purse out of a sow's ear.

Walmart sells acetone in the cosmetic dept. namely the nail polish isle. I bought a 16 oz. bottle yesterday for under $3.00. Just be sure to get the (very clearly marked) 100% pure acetone by Onyx.

 That's a fairly polarizing parody that could actually serve to ignite an invective flash point. Think about this one closely since it does contain an elusive tip that only a few will 'justly' grasp. No response necessary. |
