What is more 100 percent acetone Acetone that you get at a hardware or paint store or acetone nail polish remover?

If you buy something at a hardware or paint store labelled "acetone", it should also specify the purity, or perhaps the maximum impurity (something like "98% pure" or "< 0.5 % water")

Acetone nail polish remover probably won't. It should have an ingredients list, but that only tells you what's in it, not how much.

It's a good bet that the bottle labelled "acetone" is considerably more pure than a bottle labelled "nail polish remover", because most nail polish removers I've seen have significant quantities of other solvents (ethyl acetate, for example).
