[quote NamVetLesTreasureSeeker]Hi Hoosier, I'm not familiar with the Acetone Dip Method!! Can you give some more details on this method, such as how long you dip it or leave it setting in the Acetone Container for a period of time? Is this method SAFE for both the COIN/PERSON? Do you need to WEAR ANY GLOVES for safety? Also, our you familiar with the Peroxide Method to clean dug coins, and if so, which is better/safer? Curious minds want to know!! MANY THANKS, Les Robinson[/quote]
First off, you must use 100% pure acetone (avail at any hardware in paint section) and not the stuff used to remove fingernail polish. It has been found to be safe on almost any coin and is 100% more safe than the contaminants that you are trying to remove. This method has been used for years by numismatists to remove damaging debris without harming the coin. If a coin does indeed have green Verdigris and it is left on, the coin will be completely worthless ( to coin collectors) in a very short time as it will eventually eat the detail completely away. This acetone method is also used on coins that have been stored in containers that contain active PVC which will also destroy a coin quickly.
Short dips (30 sec - 1 min. at a time) until it comes off. Do not let the coin "soak" in the acetone. Yes, wear gloves, well ventilated area, and DON'T SMOKE! I would suggest that you don't do this with all dug coins but only the ones that you think may have Verdigris (Blue/Green color) contamination. It is just about the only method that has been found to help in most cases. Also Verdigris will spread from one coin to another so don't store one with any good coins until it is removed.
