<p>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.</p><p>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; and compositions directed to the same.</p> |
