hot water extraction could take six to 12 hours to dry. The amount of dry time needed depend-ed on the carpet pile and soil conditions, and mechanical drying options such as air movers improved the results. Today, with improved vacuum technol-ogy, hot water extraction drying times are commonly one to four hours, Snow says. This drying time rivals VLM cleaning and it is certainly not keeping carpet unusable for the length of time that it did decades ago. “Most of that work is after hours or on the weekend when there’s little to no staff so that half hour to two hour drying isn’t a con-cern,” Snow continues. “And they’d rather have the, what we perceive, the much better cleaning than VLM offers.” Facilities that operate 24 hours a day are the exception when it comes to after-hours commercial carpet cleaning, accord-ing to Snow. Airports, hospitals and casinos will often section off carpet areas so that they can be cleaned and then allowed to dry. Even in these operations, Snow finds that carpet cleaned with hot water extraction can be dry enough to soon be serviceable again. The Decision: Monitoring Results Though drying takes a bit longer, Snow states that hot water extraction still offers his clients the best results. “Yes, we feel hot water extraction is more effective being it actually removes the soil,” he notes. “The flushing action of the hot wa-ter extraction is removing the soils. It’s not … encapsulating the soil. It’s actually re-moving the soil.” “We feel the carpet stays clean longer because any soiling is new soil,” Snow con-tinues. “It isn’t all about higher productivity and using less water and gas, it is about de-livering the best product for our client.” When it comes to VLM, Pearson says carpet cleaned using his system will end up staying clean longer. According to Pearson, carpet spots will not reappear after cleaning, and the need for spot removers is greatly reduced.
