As I do, I'd listen to the experts here. They know there business and have many more years experience than myself.

I will not quote them as not needed. But will quote myself because of my past experience and also they did not quote me entirely.

Results from 24 hour acetone soak 4-5 months later. No sun light. Just my stupidity for not taking the proper care at the time. Thanks, Doug.

no, it won't hurt the coin, just rinse in pure water if you wish.

I've had several copper coins end up with an iridescent rainbow hue after soaking in acetone. whether the acetone is technically, solely and directly responsible I can't say, BUT, it wasn't there before the acetone soak.

SPP_Ottawa, while not a chemist (but can be considered expert on copper coinage) frequently refers to the effect acetone can have on UNC copper under certain light situations.

It doesn't matter how you clean a coin so long as you can't tell it was cleaned afterward. Use a jackhammer and wire brush if it doesn't show.

The fact is though that most abrasion and most chemicals that affect the coin or its corrosion products will show on the end result and will damage the coin.

If you want to learn how to clean coins then get some pocket change, a good magnifier and practice. It's a good idea to get your own experience rather than only listen to experts. You'll find that acetone will not damage coins but in rare cases it will remove dirt that had been hiding something very very ugly. This is just one of many reasons you want experience cleaning coins; the true art is to know which coins to clean and which not to clean.

Just make sure you know what you're doing before you clean a valuable coin. Coins that appear to be cleaned can lose substantial value. They can lose their entire numismatic premium.

Always rinse in fresh acetone, not water.

Like Kevin43 said thank you,very useful info
as I'm also considering trying acetone.
Having said that,this is my result of cleaning
a coin with not so traditional methods.
The Victoria cross , his Moustache and the
vertical beads were visible.
Have a look. Unfortunately no before pictures
