[QUOTE="Kurisu, post: 6586384, member: 117063"]After less than 24 hours the acetone won't be having any further effect...so overnight is typically plenty. Xylene the kind from a paint store (or even more pure Xylenes which is what I use and must be ordered from a chemical supply company) is like acetone on steroids and wont effect toning either...except where the toning is coming from trapped moisture or biological matter. Both acetone and xylenes will completely remove moisture from the coin which is good! Similar to an opal...some of the toning color comes from atomic sized trapped moisture in the the surface, so you can notice a slight toning change when using either product. As mentioned above Xylene is real a brain scrambler (much more so than old model glue base which is Amyl Nitrate) so use in a well ventilated area!!! Your home will smell like model glue if you have to much of it evaporating! Both acetone and especially Xylene evaporate unbelievably fast...so if your jar isn't sealed maybe make a little mark on the side where it's filled to, because if it's going down at all it's likely to be gone by morning!!! And would redeposit gunk on your coin. If you end up having some unattractive toning left over that you want to remove I would recommend a product like E-Z-est, but diluted with distilled water. As it very quickly begins to effect the actual metal surface of the coin. I dilute it at least 10 to 1 with distilled water...give the coin a swish in it for literally just a few seconds...then I rinse the coin for at least 30 seconds under running water COMPLETELY remove all of the e-z-est (rotating it to get the edges too, wearing rubber gloves too, keeping my other hand underneath it just in case!)...then I re-swish the coin in pure distilled water so that there are no spots from impure water. I prefer to air dry it with canister air (holding it tight by the edge so as not to blow it away lol!) and then set it on something soft like a fresh towel (100% cotton only) to completely air dry. "Dipping" a coin for too long in pure E-Z-est is a quick way to create those blast white looking coins that a lot of us instantly recognize as having been dipped![/QUOTE]
