Acetone put it there, acetone should take it away again.

Interesting. My acetone--100% acetone--comes in metal 'steel?' cans from hardware/home improvement retailers. I avoid plastics when dealing with acetone. Well, given the results descibed in this thread, I guess that's a good default approach. But on other threads, the polarity scale of solvents and substrates has been discussed. Polyethylene is at one end of that scale (nonpolar), and will not interact with acetone which is a bit more polar. Polyethylene is what plastic milk bottles, and the small bottles used to package acetone and isopropyl alcohol (think drugstores) are made from. Yeah, and ziplock bags (and tons of other things). I don't use acetone very much, and don;t like to keep large amounts of it around due to its hazardous properties, so I buy it at CVS in small plastic containers. Edited by tdziemia

Let this thread be a reminder to everyone: whenever using acetone with plastic objects, always test the plastic in acetone first. And test it for as long as you plan to soak your coins.
Plastic is so ubiquitous in our modern society, we sometimes don't even notice or think about it. All kinds of everyday objects can be damaged by acetone, just because they're made of plastic or held together by plastic parts. The surface finishing on your furniture, the lenses in your eyeglasses, even your clothing can be made of acetone-soluble plastic. Coins are one of the few everyday objects we can be quite certain won't dissolve in acetone, since we know they're made of metal.
My general rule: don't use acetone in or on anything you might want to keep and use afterwards for any other purpose.

Might be useful to share that one plastic which is not dissolved by acetone is "nylon" -- you know that black plastic you see used for kitchen utensils? I was looking for a way to handle coins while in acetone without using my naked fingers or metal (which can scratch the coin easily) or gloves (both nitrile and latex and pretty much everything which is used for adherent gloves melts in acetone; only safe one is butyl which is expensive and not easy IMO to work with). So, I got a pair of nylon tongs and tested it in pure acetone for weeks without any issues!  random picture posted below   |

 I use a baby food bottle, just the right size and the top screws on to slow evaporation. Edited by Sharks

Acetone in plastic container?
Not in Canada . Sold in metal can only.
Acetone (100 per cent ,high grade industrial ) would
melt the plastic!
