ABSTRACT:
An improved method and means for eliminating scratches and other mechanical surface damage from plastic surfaces. The method consists in applying a liquid of suitable composition to the surface of a plastic object, allowing in a short period of time for the solvent to soften the plastic substrate, and removing the liquid by draining and evaporation. No abrasive, filler or polishing compunds are required. Suitable liquids include those comprising a solvent for the plastic and a non-solvent diluent and a small quantity of surfactant.
