An improved composition of matter and method of use for removing cured coatings of paint or varnish or other similar coatings from substrates. The composition comrpises chlorinated solvent paint strippers (especially methylene chloride (CH2CI2)), waxes and an additive selected from the group consisting of decanolactone (C10H18O2), N-methylpyrrolidone (CH3NCH2CH2CH2CH2) and butyrolactone (OCH2CH2CH2CO). The additive retards the evaporation of the solvent resulting in a composition that is environmentally less hazardous to a user and also resulting in improved stripping effectiveness.
