Paint stripper, or paint remover, is the generic name given to solvent mixtures designed to remove paint and clean the underlying surface. The principal active ingredient is usually dichloromethane. Formulations with orange oil (or other terpene solvents), N-methylpyrrolidone, esters (often dimethyl esters of shorter dicarboxylic acids, sometimes aminated, eg. adipic acid or glutamic acid), aromatic hydrocarbons, dimethylformamide, and other solvents are known as well. The formula differs according to the type of paint and the character of the underlying surface.

Paint strippers come in a liquid, or a gel ("thixotropic") form that clings even to vertical surfaces.

The principle of paint strippers is penetration of the paint film by the molecules of the active ingredient, causing its swelling; this volume increase causes internal strains, which, together with the weakening of the layer's adhesion to the underlying surface, leads to separation of the layer of the paint from the substrate.
