What is a Hot Water Extraction ("Steam") Cleaning Method?

Hot water extraction, or steam cleaning*, is a cleaning method that begins with dry soil removal (vacuuming) followed by preconditioning. Then, hot water is applied [110° to 165°F (49° to 83°C)] to the carpet from a holding tank or heating coil incorporated into the cleaning unit, often combined with detergent. The pressurized solution is injected into the carpet. Suspended soil is removed by combining the flushing action of injected solutions with wet vacuuming. [Note: Ad or content links featured on this page are not necessarily affiliated with IICRC (The cleantrust) and should not be considered a recommendation or endorsement by IICRC (The cleantrust)].

Solution and suspended soil are collected within a wastewater recovery tank or disposal system. This method can be used on carpet whose fibers, dyes and construction are not adversely affected by water-based cleaners, as long as overwetting is avoided and thorough wet vacuuming to remove excess moisture occurs.

 

*Note that "live steam" is not employed in this cleaning process, only warm or hot water. "Steam cleaning" is commonly used as an accepted term to describe this cleaning method.
