Abstract
A method of cleaning carpets with a composition comprising a surfactant selected from amine oxides and acyl sarcosinates. The compositions are advantageous in that they do not leave a dulling film if not removed from the carpet after drying. Preferably, the compositions also contain a source of active oxygen for stain removal.
