There are five key components to carpet cleaning, and according to Joe Versluis, U.S. Products , these can be referred to by the acronym “DASCH.”


Here is what DASCH stands for:


D: The "D" refers to dry soil removal, which is accomplished usually by vacuuming. According to Jeff Bishop of Clean Care Seminars, Inc., "It is unreasonable to suggest that dry soil removal is not essential to perform before wet cleaning begins."


A: "A" refers to agitation and is fundamental in all cleaning to loosen soils. In carpet cleaning, according to Bishop, it helps ensure uniform chemical penetration and distribution for more effective cleaning.


S: "S" is for soil suspension, which occurs once dry soils have been removed from the carpet. The goal of soil suspension is to separate soil from carpet fibers so it can be removed in the extraction process.


C: The proper use of effective chemicals, the "C" in our acronym, is essential to successful carpet cleaning. Chemicals are used to prepare the carpet for cleaning, according to Bishop, reducing surface tension and dissolving and emulsifying soils, which can then be removed by the carpet extractor.


H: The "H" stands for heat, which is vital in effective carpet cleaning. "Heat enables faster, more efficient cleaning than cold water," says Bishop.
