Disclosed is a synergistic paint removing composition comprising a particular selection of a plurality of known solvents in very specific proportions, namely: from 20 to 45% of aromatic hydrocarbons; from 15 to 30% of dimethylformamide; from 15 to 25% of N-methyl pyrrolidone; from 5 to 15 % of a water-immiscible compound selected from the group consisting of terpene derivatives, oleoresins and mixtures thereof; and from 0.5 to 4% of at least one wetting agent, all the above percentages being expressed by weight. This composition is partially miscible in water even though some of its constituents are not water miscible, thereby making the composition easy to wash and thus preventing oily film to be left on the treated substrate. The composition according to the invention is normally in a liquid form. If desired, for some applications, a thickening agent can be added thereto to "convert" it to a gel.
