Acetone Poll: Who Uses It?

I don't think anyone is just leaving their coins in that long. also its definition of "ambient light" is missing. how many lux is that? How much water vapor? how many ppm? If a mint state coin needs cleaning, then you got more to worry about than if it has luster or not left. Copper coins would be pennies, and they probably have zinc rot that would be happening quicker than patina to be removed and likely loose "mint state" in a year or two anyway because the most recent coins are just poor quality.

The patina on copper is actually protecting it anyway, though unsightly, there is worse that could happen to a coin than verdigris. and cleaning any metal just exposes more pure metal under any dirt to harsher thing, but metals are cleaned for many reasons. We clean so what we have looks better, and hopefully for as long as we live. The coins belong to someone else later. Hopefully still in good condition but over time ALL coins will succumb to the elements.

Consider avoiding pickle jars, especially with the potential residual acids, and they're just too, too, well, big.

I bought three or four jars of baby food to use those for acetone washes, dips, sloshes and whatnot. And who doesn't like a good jar of baby food!?

Acetone will attack and dissolve the rubber seals on jar lids. I save the small jars from store purchased minced garlic and usually toss them away after several uses because of the gasket failure.(depending on duration of each use)

It is best to store acetone in the container as purchased.

Don't worry, it's organic.

There is no gasket on my pickle jars, just glass jar and metal lid, and um... isn't all garlic organic? I would be afraid of synthetic garlic.

Yes, I was not inferring to non organic or even organically grown garlic, I was referring to acetone dissolves all organic matter.
