Encapsulation Carpet Cleaning Technology Explained How soil affects carpet Most dry soil in a commercial setting can be readily removed by routine dry vacuuming. It’s the oily and sticky soils that attract and hold dry soil to the surface. The result is a dull, gray, and ugly appearance. Encapsulation chemistry cleans better and helps carpet stay clean longer The first step in effectively cleaning any carpet is to counteract sticky soils. The encapsulation chemistry surrounds each soil particle and crystallizes so it can’t attract other soil. The encapsulated particles release from the fiber and are easily extracted with normal vacuuming. And since there's no dirt attracting residue left behind, the carpet stays clean longer.
