> Acetone is blissfully not so toxic...

I'll say. Oak Ridge National Lab has this to say about the toxicity of acetone:

> Acetone (CAS No. 67-64-1) is a clear, colorless, highly flammable liquid with a vapor pressure of 182 mm Hg at 20C (Morgott, 1993). It is completely miscible in water and soluble in organics such as benzene and ethanol (ATSDR, 1994). Its log Kow has been estimated to be -0.24 (ATSDR, 1994). Acetone is used primarily as a solvent and chemical intermediate, and it is also found in some consumer products such as nail polish remover (Inoue, 1983; Kumai et al., 1983).

Given a choice between the chlorinated stuff, and something one can drink half a shot glass of and not suffer any toxic effects, I'll take the acetone any day.

I generally buy my acetone online, BTW. It's relatively easy to buy small quantities of pure acetone, because it's sold as nail polish remover.

Fun fact: if you drink isopropyl alcohol, your body metabolises it (partly) to acetone, which you can smell and taste. But, well, don't drink either anyway. :-)

Well, even in California, you can buy pure acetone OTC – you just have to interact with a human cashier who probably won't even know why the self-checkout refuses to let you buy it. I don't care one way or another except that the big box stores try to push you towards the self-checkout lanes.

Nail polish remover, like non-ethyl alcohol, is likely to be adulterated (e.g. with scents or crap to soften your cuticles, etc.). Depending on how clean you need something to be it may be an issue (and you probably can find high test nail polish remover). I was removing these infernal stickers from cooking implements so I went with the big box store. Depending on what you're working with you may still need to wipe it down with isopropyl anyhow.

Not if you buy the stuff that literally says "pure acetone," e.g. https://www.amazon.com/Onyx-Professional-Acetone-Remover-Fas...

I was going to suggest that the only "adulterant" likely to be in something labeled "pure acetone" would be water from the air, but Stack Exchange suggests differently: https://chemistry.stackexchange.com/questions/54341/acetone-...

Acetone bought from your local shop that sells car spare parts, tools, and whatnot is likely several orders of magnitude cheaper than the same acetone bought from the cosmetics department. I keep offering my bottle of acetone to my SO but she insist on using the cosmetics department version. ;)

I think many nail polish removers aren't pure, so you have to check. Usually hardware stores have cans of acetone without any additives.
