The present invention is directed to apaint stripping composition comprising (a) from about 0.5 to about 50% by weight of an aromatic alcohol, such as benzyl alcohol; (b) from about 0.5 to about 20% by weight of malic acid; and (c) from about 15 to about 60% by weight of water. The pH of the composition broadly ranges from about 2 to about 3. The stripping composition of the present invention is free of chlorinated solvents, environmentally safe, and user-friendly. It is non-corrosive or only slightly corrosive to substrates, non-flammable, non-toxic, low odor, and fully biodegradable. A method of preparing the paint stripping composition is also provided.
