Abstract:
1. A method of neutralizing a stain on a surface, the method comprising: applying a first effective amount of a composition to a stain on a selected surface to affect a color change thereon, the composition comprising a liquid carrier and particles, the particles comprising a homogeneous mixture of a first additive and at least one polymer selected from the group consisting of a polyolefin, a polyurethane, an acrylic, an acrylate, a polyamine, a polyamide, a polyamid, a polyimide, a polyether, a polystyrene, a polycarbonate, polysulfone, a polyester, a polyalkyleneoxide, a polysiloxane, a polysulfide, a polyethyleneimine, a cellulose, a wax, a paraffin, a phenolic, an elastomer, a vinyl, a hot melt adhesive, a hydrophilic polycarbodiimide, a polysaccharide aldehyde derivative, a bismaleimides, a silicon, a soya oil, a linseed oil modified alkyd, a copolymer, a homopolymer, and mixtures thereof; allowing the composition to substantially dry on the surface to attach the particles to the surface; neutralizing the stain on the surface by removing the attached particles from the surface; after removing the attached particles from the surface, visually determining if a residual stain material remains on the surface; and when the residual stain material remains on the surface, masking the residual stain material on the surface by applying a second effective amount of the composition to the residual stain material and applying heat or a chemical to the second effective amount of the composition to durably affix the composition to the surface.
