Abstract
Abstract Vinyl decals are removed from a painted surface without damaging the painted surface by contacting the decal with a composition consisting essentially of one or more of the following aromatic solvents: toluene, xylene and aromatic naphtha; and methyl ethyl ketone or a mixture of glycol ethers. The composition may optionally contain a thickener. The composition remains in contact with the decal for a time sufficient to loosen the decal from the surface and then the decal is physically pulled from the surface.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
96 words
A method of removing a vinyl decal from a painted surface without substantially damaging said painted surface at temperatures between approximately 0° and 55° F., said method comprising the steps of: contacting said decal for a time sufficient to loosen said decal from said painted surface with a chemical composition consisting essentially of between approximately 35% and 75% by weight methyl ethyl ketone and between approximately 25% and 65% by weight of an aromatic solvent selected from the group consisting of toluene, xylene and aromatic naphtha; and physically removing said loosened decal from said painted surface.
