1. The process of carpet cleaning used by End of Tenancy cleaners in London Although there is an actual steam cleaning industrial process, in the context of carpet cleaning, "steam cleaning" is, in fact, hot water soil extraction cleaning, which is professionally known as HWE. The hot water soil 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. Many carpet manufacturers recommend professional hot water extraction as the most effective carpet cleaning method which also provides a deeper clean. Actual steam could damage man-made carpet fibers and change the characteristics as they are usually set using heat. Natural fiber carpets such as wool can shrink, Velvet piled carpets and Berber carpets will become fuzzy which is known as pile burst. Hot water extraction equipment may be a portable unit that plugs into an electrical outlet, or a truck mount carpetcleaner requiring long hoses from the truck or trailer. Truck-mounted equipment may be used where electricity is unavailable, but may be unsuited to premises distant from a driveway or road, and require hoses to pass through windows to reach the upper floors of a building. The hoses needed for truck-mount and professional portable carpet cleaning may present a trip hazard, and allow pets or children to escape through doors left ajar. Heated or air conditioned air can also be wasted when doors are left open for hoses. Truck-mounted carpetcleaning equipment minimizes the noise in the room being cleaned, but may cause noise and air pollution offensive to neighbors, and could violate anti-idling bylaws in some jurisdictions. However, truck-mounted cleaning is much faster than portable equipment, and the extra heat will dissolve more spots and stains, and more vacuum suction power will reduce drying times. 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, and then agitated with a grooming brush or an automatic scrubbing machine. Next, a pressurized manual or automatic cleaning tool (known as a wand) passes over the surface to rinse out all pre-conditioner, residue, and particulates. If an alkaline detergent is used on a woollen carpet, use of a mild acetic acid solution will restore neutral fiber pH. The acidic rinse thus neutralizes the alkaline residues, and can contribute to softening cleaned fabrics. The hot water extraction method is the preferred method of many carpet manufacturers as it removes more dust and abrasive particles resulting in less wear and pile abrasion. 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 bonnet or shampoo cleaning, proper extraction and air flow are critical to avoid drying issues such as mold growth & browning of wool fibers. Drying time may also be decreased by extra use of fans, de-humidifiers, and outdoor ventilation. Dry cleaning option Many dry carpet-cleaning systems rely on specialized machines. These systems are mostly "very low moisture" (VLM) 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 "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. The solution may add a solvent

The amount of time the pretreatment dwells in the carpet should be less than 15 minutes, due to the thorough carpet brushing common to these "very low moisture" systems, which provides added agitation to ensure the pretreatment works fully through the carpet. The benefit of dry carpet cleaning, over wet solutions, is that dry chemical compounds don't attract dirt, like dried shampoo.[citation needed] While dry carpet cleaning is more expensive and more time consuming to clean than bonnet or extraction, dry cleaning formulas put less stress on the carpets themselves.
