Abstract
Abstract An aqueous cleaning composition for carpets, rugs, and textiles has been discovered with the composition comprising sodium lauryl sulfate, an ethylene glycol monohexyl ether, a fluorosurfactant, a carboxylated polymer salt, and a tetrasodium ethlyenediamine tetraacetate. The composition is effective in removing a variety of stains from carpeting and is particularly effective against oily stains without imparting undesirable properties on the cleaned surface.
