Abstract
A process for cleaning a metal, plastic or wood surface on which there is a residue resulting from contact with a cured resin which comprises applying to said surface a solution of a copolymer of N-vinyl-2-pyrrolidone and maleic acid, drying said solution of N-vinyl-2-pyrrolidone and maleic acid copolymer to form a film, and separating said film from said surface.
