Abstract
Protective paper adhesively bonded to stainless steel surfaces is removed by applying an aqueous solvent mixture containing a ketone or similar solvent, alcohol, toluene, and a wetting agent, all of which are maintained in a single phase. The relative composition of the solvent components is maintained on the area of solvent application by covering with a suitable airtight cover. The single-phase solvent mixture penetrates the paper and adhesive, and the vapor pressure of the solvent mixture causes the paper and adhesive to blister and loosen. The paper is peeled off after sufficient time elapses. Any remaining adhesive can be removed with a second solvent containing a ketone and toluene.
