One trick: has to be pure. Contaminants, as from waste acetone, must be filtered out or stripped or else the engine can run VERY rough.

So is the acetone sold at Home Depot or wherever pure enough for use in a car?

I would assume so. Purity should be stated on the can.

If it isn't, I think I'd shop elsewhere, as for instance a chemical supply store (probably cheaper there anyway).

Acetone is not an expensive chemical, as such things go. I shold prefer strongly to buy a bit more quantity than to pay a substantially higher price for a small, 1-fill-up quantity.

Also -- very important -- OBEY the storage instructions! Acetone is highly volatile under certain circumstances. You don't want any part of that game, m'friend, not at ALL!

FReegards!
