Title: Gas jet removal of particulated soil from fabric

Abstract: Fabrics are cleaned by treating at least a portion of the piece of fabric with a particulating chemical, and agitated by a gas jet of a particle-dislodging gas to dislodge the particulated soil. The particulating chemical loosens embedded non-particulate soil and converts it to a particulate form, which is then separated from the fabric by the particle-dislodging gas.
