Abstract
This invention relates to new compositions and methods for cleaning textile substrates, especially carpet and upholstery fabrics. More particularly, this invention relates to liquid compositions that contain absorbent particles in a flowable fluid dispersion, which dries to a soil ladened powder, that can be removed by vacuuming, brushing, and/or laundering methods. The composition includes dispersion stabilizing additives such that the composition is presented as a stable dispersion or as a composition that may be easily redispersed prior to application.
