No, don't use acetone or the like in a garage; too many pockets &
corners for it to collect the fumes in, even with forced
ventilation.

It's an accident waiting to happen.

Detergents will work, and there are also cleaners made
specifically to remove gas & oil from the concrete - visit a
local NAPA or similar auto goods store.

Good advice Pop, I stand corrected. Of coarse one must also consider the
danger of the gasoline inside the garage as well. I'm no chemist, but aren't
gas fumes just about as bad?
