The acetone VAPOR is also highly flammable. At room temperature, those vapors are above their flash point. All they need is a source of ignition for the vapors to ignite and go KABOOM!
You are exceedingly lucky to have been able to make that post, rather than be in a hospital ... or dead.
You know when you have copper or copper plated zinc cents in the environmental condition that you found them in , nothing you can possibly do to them will make them collectable . They will always be corrosive detailed coins .
After separating the zinc from the copper pennies I did the boil again with just the copper coins and I was very surprised how clean they actually came. They may not be collectible to anybody else but I will keep them myself in my collection so that is no loss. I do believe I may have found something interesting for my collection in there anyways. It's also nice to know how to clean other brass and copper items.
As for the acetone. My house was well ventilated with windows open and the acetone stayed far away from the flame with the exception of that one very quick picture but I do also keep a fire extinguisher right there in the kitchen at all times. Thanks for the little knowledge about the meth labs though. Lol I did not realize how combustible it truly was until then so I will take the advice into consideration and not do it again. Thank you for your concern.

Go to auto parts store and ask for battery acid. Use this to soak all those coins for about one week. Then rinse with vinegar for another week. Now if anything is left, use it as a paper weight.
Lovely suggestion just Carl. I guess they say it is better to be a *** Edited by Staff | The bad word filter is in place for a reason. Bypassing the filter and making the intended word obvious anyway is completely unacceptable. *** I think I will stick to what I have already done though. thanks anyway.
Have you heard of the St. Francis Hotel in San Francisco before? They have an actual coin laundry on the premise. Not exactly numismatic friendly, but not the point either.

Money laundering.... I do not think it means what you think it means.
I get expirimentation coins at the scrap yard in the trunks and anywhere else that is wet. Once I was in a car with a bunch of broken slabs from really nice coins but no coins found in there. I did have permission to do this so don't be worried. I look for the coins while pulling parts from the vechicles.
