Acetone

Simple. The manufacturer added 100% Acetone to the mixture. In other words that STUFF does contain some of the 100% Acetone. A legal twisting of wording by manufacturers.
Although the fragrances are usually in a gasous state and do not show up in a vaporasation test, they do effect other materials such as metals. And too the lable doesn't really tell you all the ingrediants in most situations. Not lying but fingernail polish usually contains softeners so as to not damage the fingernails. Remember that most manufacturers of any product do not want their products copies so the real, actual percentages of all items is sort of buried in legalization terminology.
Summation is don't use fingernail polish remover on coins.
As noted on this forum many times just go to a hardware store and buy a can, usually a quart size. Always test it in case it's shelf life has been extensive.

NO WAY I'm using needle-nose pliers to dip my coins. Maybe it's just me.

So using acetone is okay? Is it ok to use on ALL coins or just the least valuable ones?

Ahhhh....be a man and use your fingers. It's not that big of a deal.

Two serious problems with that video- metal pliers and no fresh acetone rinse. The pliers will no doubt damage the rim and the contaminants were diluted but spread over the entire coin without a fresh rinse.

I am not talking about a water rinse, you need to rinse the coin with fresh acetone. Water, even distilled, will leave spots but the acetone will remove any remaining contaminants and all traces of water so no spotting.

That was my point, steel is much harder than silver.


I actually do have a pair of plastic coin dipping tongs, they are composed of polypropylene which is not affected by acetone.


The bamboo would not hurt the coin at all as it would be softer than coinage metals but chances are that the bamboo would have some sort of varnish on it the the acetone would strip off.



Acetone is essentially harmless to your skin as long as you minimize contact. Little known fact- acetone is a metabolic byproduct of the human body, you already have a little bit of it in you Yes, it will strip the natural oils from your skin but you will not see a dermatitis reaction like you would with other solvents(xylene, benzene, etc). If you do not want contact with skin at all, you can use nitrile or chloroprene gloves. The main hazard concerns from acetone are flammability and volatility, the vapors can be intoxicating if you are exposed to them for an extended period.
