The invention provides a carpet cleaning composition and dispensing means which use foam producing surfactants, solvents, propellants, builders and water. Other adjuncts may be added, such as fragrances, dyes, and fabric softeners. The invention also provides a method for cleaning soiled fabrics having fibers containing soiling particles which comprises: (a) applying to said fibers an aqueous, solvent/surfactant admixture having a solvent with consistent evaporation rate in ambient air; (b) collapsing without abrasion said mixture into said fibers and emulsifying and segregating said soiling particles during a controlled residence time; and (c) evaporating said solvent so as to form said admixture into a foam, elevating said soiling particles substantially to the surface of said fibers.

A dispensable composition for cleaning soiled fabrics, comprising: (a) about 0.1% to 30.0% by weight of a foam forming surfactant; (b) about 0.5% to 20.0% by weight of a volatile organic solvent having a consistent evaporation rate in ambient air, said solvent having, a vapor pressure of 760 mm of m

A dispensable composition for cleaning soiled fabrics, comprising: (a) about 0.1% to 30.0% by weight of a foam forming surfactant; (b) about 0.5% to 20.0% by weight of a volatile organic solvent having a consistent evaporation rate in ambient air, said solvent having, a vapor pressure of 760 mm of mercury at a temperature of no greater than 175°C.; (c) about 10.0% to 50.0% by weight of a propellant wherein if said propellant is a hydrocarbon or mixture of hydrocarbons, said propellant will not exceed about 4 carbon atoms in length; (d) about 0.5% to 20.0% by weight of a builder; and (e) the remainder as water; said surfactant and solvent admixing and interacting with said propellant so as to form an initial foam upon dispensing, to collapse without abrasion into a fabric surface and to refoam.
