Abstract
A universal paint solvent comprises, on a weight basis, 1-30% of an acidic material selected from the group consisting of sulfonic acids, phosphonic acids, phosphoric acids, and combinations thereof; together with 10-80% of an organic solvent selected from the group consisting of alcohols, ethers, ketones, aldehydes, esters, and combinations thereof. In particular compositions, the acidic component is comprised of a mixture of two different acids. Alkyl esters, particularly acetate esters, are preferred organic solvents. Butyl acetate is a specifically preferred solvent. The compositions solvate a large variety of different paint formulations, and are effective at room temperature. The compositions have particular utility for cleaning paint delivery systems and equipment.
