Acetone Help

Go to top of page and in the SEARCH place type in Acetone. There should be lots and lots of topics to read on the subject.
To make it easier. Put the Acetone in a glass cup and cover it. If the Acetone does not remove whatever you are trying to remove, the stuff your trying to remove may be something that will not come off easily.

Be aware that acetone is an organic solvent so it will only remove organic material. If your coins are that crusty, there is probably some corrosion at play and acetone is useless for that. In most cases, you should see results in a minute or so but the coin will not be harmed with a longer soak.

The best kind of container is one that the coin can stand up in so the need for flipping is negated. I use an item called a Coplin jar- it is used for staining histology slides and it has grooves inside that are perfect for holding coins upright http://www.coleparmer.com/catalog/p...?sku=4858530. The one in the link is a bit pricey, they can be had for less than $10, but it is a good picture. BadThad also outlined a good rinse procedure in a recent thread https://goccf.com/t/20377.

The container with the acetone that you are using should be covered. It is wasteful but more importantly- acetone vapors are flammable and intoxicating(and not the good kind, that would be ethanol...) so you want to minimize evaporation especially inside your house. Even with the container covered you should be working in a room with a vent fan such as a kitchen or bathroom.

Always remember, safety first!

If you allow the acetone to evaporate, it will simply redeposit whatever it has dissolved back onto the coin.
