Carpet manufacturers and carpet cleaning technology have made tremendous advances in recent years. There have been improvements in not only the materials, but also superior equipment and substantial advances in the chemicals used to clean as well. These considerable improvements have made it possible to help professional carpet cleaners get great results.
For many years, there has been a reoccurring problem with nylon carpet pile. The difficulty with this type of carpet fiber is that it has a tendency to soil rapidly, and although there have been improvements, they just conceal the problem instead of prevent it. Several approaches towards solving this problem have been made including stain blockers, which tend to protect the fibers from being penetrated by liquids.
Many of the carpet cleaning equipment manufacturers have put their focus on developing extraction machines that operate with low moisture which solves the problem of overwetting. These low moisture methods achieve high-quality results in cleaning the nylon carpet pile, and the benefit of this type of carpet cleaning is that it allows your carpets or furniture to dry quickly.
The biggest danger, by far, from too much water in your carpet is getting the underpad wet. The reason this is a concern, you cannot get enough air circulation under the carpet to dry it properly. For that reason, the most predominant advantage of these low moisture carpet cleaners is that it helps to prevent mold growth in your home.
The most significant of all of the latest advances in carpet cleaning technology is in the chemicals themselves. They employ a science called encapsulation. This chemical process utilizes a revolutionary encapsulation technology that literally traps soil, dirt and residues in a suspension and is subsequently removed by a machine. In the past encapsulation has been associated with brush and bonnet cleaning or dry foam but with recent advances in the science you will also find encapsulation being used with hot water extraction methods.
Most dry dirt can be easily removed by a routine of regular vacuuming. The oily and sticky dirt's attract and hold dry soil to the surface. The result is a dull, gray, and ugly appearance. Encapsulation chemistry not only cleans better, but also helps the carpet stay clean longer.
The first step in effectively cleaning any carpet is to counteract sticky soils. The encapsulation chemistry surrounds each dirt particle and crystallizes so it cannot attract other dirt. The encapsulated particles release from the fiber and are easily extracted with normal vacuuming and since there is no dirt-attracting residue left behind, the carpet stays clean longer.
Even when using a fiber rinse as part of hot water extraction cleaning, some detergent residue is still left on the carpet. Many fiber rinses themselves are sticky! Some carpet mills estimate that up to 4% of detergent used is left in the carpet following hot water extraction, and this residue adds up over repeated cleanings. Any new dirt coming into contact with the carpet, such as dirt from shoes in normal foot traffic, will be attracted to the sticky detergent residue left on the carpet. This is referred to as "rapid resoiling", the result of cleaned carpet getting dirty faster than carpet with no residue. Vacuuming removes loose soil, but will not remove dirt attached to sticky residue.
Many encapsulating products are formulated with the proper balance of carpet cleaning detergents that get the carpets clean in the first place, and crystalline polymers that effectively encapsulate and crystallize embedded spots, greasy soils and detergent residues. The encapsulation technology is a much more effective carpet cleaning method because it crystallizes any remaining residue, thus preventing rapid resoiling.
