  • Patent number: 6673121
    Abstract: A process of cleaning textiles, including textiles that are labeled dry clean only, without the use of large quantities of environmentally hazardous dry cleaning fluids such as those containing perchloroethylene or petroleum. The process uses hand treatment of soiled areas with a cleaning agent, with subsequent washing in water, followed by washing in ozonated water to remove the cleaning agent and the water. The textile is dried using a process that does not depend on tumbling of the textile in the presence of heat to dry the textile.
