ABSTRACT:
This invention provides graffiti removers for removing permanent ink stains from painted surfaces. This graffiti removers include an active solvent for dissolving the stains, which are organic in nature, an optional secondary solvent for concentrated attack on the stain without being adversely affected by dilution with water, an emollient for maintaining a uniform dispersion of particulates in the remover and on the graffiti-stained painted surfaces, and an amorphous, particulate, mildly abrasive filler for imbiding the solvents, the filler being selected to permit the slow release of the active solvent.
