We started by cleaning carpet like everyone else… but we felt like we could do better… and we did! Corporate Clean Services developed a proprietary system that utilizes vacuum-extraction, neutral chemicals, agitation, hot water extraction, and speed drying.
Carpet cleaning, “steam cleaning” is, in fact, hot water extraction cleaning. The hot water extraction cleaning method uses equipment that sprays heated water, sometimes with added cleaning chemicals, on the carpet. Simultaneously, the water is vacuumed up, along with any dislodged and dissolved dirt.
We use hot water extraction equipment from a truck mount carpet cleaner requiring long hoses from the truck. The cleaning industry calls these truck mount units but you mostly see them inside a heavy duty van. I guess van mount isn’t cool enough.
A common process of hot water extraction begins with preconditioning. Alkaline agents such as ammonia solution for synthetic carpets, or acidic solution (such as vinegar solution) for woolen carpets, are sprayed into the carpet, then agitated with a grooming brush or an automatic scrubbing machine. Next, a pressurized manual or automatic cleaning tool (such as a wand) passes over the surface to rinse out all pre-conditioner, residue, and particulates. If an alkaline detergent is used on a woolen fibre, use of an acetic acid solution will restore neutral fiber pH. The acid rinse thus neutralizes the alkaline residues, and can contribute to softening cleaned fabrics.
Extraction is, by far, the most important step in the hot water extraction process. Since the hot-water extraction method uses much more water than other methods like dry encapsulation (low moisture) or a complete dry system (like HOST type process cleaning, no moisture) proper extraction and air flow are critical to avoid drying issues. Drying time may also be decreased by extra use of fans, air conditioning, and/or outdoor ventilation.
Many dry carpet-cleaning systems rely on specialized machines. These systems are mostly “very low moisture” systems, relying on dry compounds complemented by application cleaning solutions, and are growing significantly in market share due in part to their very rapid drying time, a significant factor for 24-hour commercial installations. Dry-cleaning and “very low moisture” systems are also often faster and less labor-intensive than wet-extraction systems.
Heavily soiled areas require the application of manual spotting, pretreatments, preconditioners, and/or “traffic-lane cleaners”, (commonly sprayed onto carpet prior to the primary use of the dry-cleaning system) which are detergents or emulsifiers which break the binding of different soils to carpet fibers over a short period of time. For example, one chemical may dissolve the greasy films that bind soils to the carpet, and thus prevent effective soil removal through vacuuming.
Dry Carpet Encapsulation uses polymers that began literally encapsulating (crystallizing) soil particles into dry residues on contact. Encapsulators are specialty detergent polymers which become part of the detergent system. As drying occurs (2-5 mins) after cleaning, these encapsulators bind the detergent molecules and residual soils in a brittle, crystalline structure. Detergent and soil particles can no longer attract other soils and are easily removed by dry vacuuming. In addition to binding the detergent and soil residues the encapsulation chemistry coats the clean fiber with the same brittle film. This reduces the fiber’s affinity for oily and particulate soils. As this brittle film “breaks away” and more soil is removed, the appearance of the fiber improves as opposed to soiling more rapidly.
