If you’ve been shopping at paint stores or in the paint department of home centers for the last decade or so, you may have noticed the increased prominence of acetone among the solvents. There is a reason for this.
Acetone is among the very few solvents that have been exempted as a volatile organic compound (VOC) – an environmental (smog) pollutant. And it is the least expensive one, by far. Acetone is exempt because it has so little reactivity.
Being exempt means there are no regulatory restrictions on how much of this solvent we, or the manufacturers we buy from, use. No other commonly available solvent, except water, is so free of restrictions.
