No Harsh Chemicals, No Sticky Residue,  All Natural Carpet Cleaning. Encapsulation cleaning is an interim carpet maintenance method. In this process, the encapsulating chemical is sprayed onto and then brushed into the carpet using a cylindrical or rotary brush machine or bonnet. The encapsulation chemical crystals surround each soil particle and crystallizes it so it can’t attract other soils. It takes the oily soils and makes them dry. It helps resist re-soiling, repels dry soils which protects carpets from oil, water and alcohol based stains. The encapsulated soil particles release from the carpet fiber and are removed by normal vacuuming once the carpet has dried.
