Wednesday''s Ask the Experts question from a cleaning professional on the International Custodial Advisors Network (ICAN) "Ask the Experts" page: I am currently carpet cleaning 18 retail stores with heavily used traffic lanes. I have tried bonnet and extraction cleaning with a portable extractor. I am still seeing large areas of wicking. I am trying to decide which is the best type of cleaning method, bonnet, extraction, or encapsulation.
Wicking is the movement of moisture in the carpet to the air above it. This is the natural means by which carpet fibers dry after wet cleaning. When various soils and detergent residues are contained in the water, as it dries into the air the contaminants will concentrate at or near the tips of the yarn filaments and become visible.
