Agitation + Crystallization = Encapsulation
The encapsulation method of carpet cleaning is becoming more and more popular in commercial carpet maintenance. These encapsulation cleaners should be used as an interim maintenance method and should be followed periodically (every 2-3 cleanings) by a thorough hot water extraction.
The carpet encapsulating chemical (a liquid cleaning agent) is sprayed on and then brushed into the carpet using a cylindrical or rotary brush machine or bonnet. The encapsulation chemistry surrounds each soil particle and crystallizes it so it can’t attract other soils. The encapsulated soil particles release from the carpet fiber and are removed by normal vacuuming which will generally be done by the janitorial staff at regularly scheduled times.
Since it's a low moisture system, carpets that have been cleaned through encapsulation can be put back into use promptly. This process allows maintenance companies to provide a continual high level of appearance at a lower price than other traditional methods while generating high levels of productivity. Encapsulation is designed for commercial maintenance only.
