after the rinse cycle, the machine begins the extraction process, which recovers dry-cleaning solvent for reuse. modern machines recover approximately 99.99% of the solvent that was used. the extraction cycle begins by draining the solvent from the washing chamber and accelerating the basket to 350 to 450 rpm, causing much of the solvent to spin free of the fabric. until this time the cleaning is done in normal temperature, the solvent is never heated in dry cleaning process. when no more solvent can be spun out, the machine starts the drying cycle.
