Abstract
Abstract This invention relates to aqueous cleaning formulations particularly useful in the hot water extraction cleaning of textile fabrics such as rugs, carpets and upholstery. The cleaning formulations are essentially free of organic solvents and comprise 0.1 to 50 grams of an inorganic or organic builder per gallon of cleaning formulation, 0.1 to 100 grams of a mixed alkyl ethoxylate (C10-C16) nonionic surfactant, with a hydrophile-lipophile balance value in the range of 10.5 to 15, per gallon of cleaning formulation, and 0.1 to 100 grams of a fluorosurfactant per gallon of cleaning formulation.
