<p>A paint-stripper composition is described which comprises a mixture of water and at least one organic solvent selected from (A-1) alkoxy benzenes or alkoxy naphthalenes or (A-2) at least one quaternary amine salt of the formula <CHEM> wherein each R is independently an aliphatic group containing an average of about 6 to about 12 carbon atoms, and X is a halogen or (A-3) a mixture of (A-1) and (A-2). A method of stripping paint from a surface also is described, and the method comprises (I) contacting the paint with a paint-stripping composition comprising a mixture of at least about 3% by weight of water and at least one organic solvent selected from (A-1) alkoxy benzenes and alkoxy naphthalenes, or (A-2) at least one quaternary amine salt of the formula <CHEM> wherein each R is independently an aliphatic group containing an average of about 6 to about 12 carbon atoms, and X is a halogen or (A-3) a mixture of (A-1) and (A-2); and (II) removing said paint and paint stripper compostion from said surface.</p> |
