(March 2015) (Learn how and when to remove this template message) After club soda mixed with cleaning product, other products are also possible, is deposited onto the surface as mist, a round buffer or "bonnet" scrubs the mixture with rotating motion. This industry machine resembles a floor buffer, with an absorbent spin or oscillating pad that attracts soil and is rinsed or replaced repeatedly. The bonnet method is not strictly dry-cleaning and involves significant drying time. To reduce pile distortion, the absorbent bonnet should be kept well-lubricated with cleaning solution. Its not recommended to dunk the bonnet in a bucket of cleaning solution and then wring it out with a mop-bucket wringer, then the bonnet is to wet. Its very important to change or turn the bonnet early, Bonnets can become filled with soil in just a couple hundred square feet. And once loaded with soil, the bonnet will not hold any more; instead, it simply moves the soil from one area to another. The overly wet bonnet also deposits residues that attract soils when they are dry, creating the need to clean more often. Its recommended for robust and not for high floor carpet, it swirls the floor. It distorts pile and grinds dirt deeper in carpet fiber also it has an abrasive effect. When there is a large amount of foreign material in the carpet, extraction with a wet process may be needed. Normally, the spin-bonnet method may not be as capable of sanitizing carpet fibers due to the lack of hot water, for this a spezial thermo machine is needed, here the buffing machine is equipped with a heating, to heat up the bonnet, but a post-cleaning application of an antimicrobial agent is used to make up for this. Compared to steam cleaning, the small amounts of water required with spin-bonnet carpet cleaning favor water-conservation considerations. It only cleans the top of the carpet 1/8 inch but its very fast for wide areas. But bonnet cleaning is not the best mechanism for completely removing the chemical that is pre-sprayed onto a carpet. Its recommended that only surfactant free or encapsulating products are used. On the other hand, the re-soiling is great. Shampoo Wet shampoo cleaning with rotary machines, followed by thorough wet vacuuming, was widespread until about the 1970s, but industry perception of shampoo cleaning changed with the advent of encapsulation. Hot-water extraction, also regarded as preferable, had not been introduced either. Wet shampoos were once formulated from coconut oil soaps; wet shampoo residues can be foamy or sticky, and steam cleaning often reveals dirt unextracted by shampoos. Since no rinse is performed, the powerful residue can continue to collect dirt after cleaning, leading to the misconception that carpet cleaning can lead to the carpet getting "dirtier faster" after the cleaning. The best method is to combine shampoo and extraction, first shampoo with a spin brush to loosen the dirt and the pile, then extraction the carpet. But this needs time and double rinsed is necessary and the drying time is up to 24 h. When wet-shampoo chemistry standards converted from coconut oil soaps to synthetic detergents as a base, the shampoos dried to a powder, and loosened dirt would attach to the powder components, requiring vacuuming by the consumer the day after cleaning.

(March 2015) (Learn how and when to remove this template message) Dry foam cleaning involves applying cleaning foam and immediately vacuuming the foam. It is not a completely dry method since the foam is 90% air and 10% liquid. A dry foam machine consists of a pressure tank in which a solution of water and shampoo is added. This method is used for water sensitive carpets, needle felt, and other carpet types whose construction inhibits sufficient water extraction.
Vacuum wash This section does not cite any sources. Please help improve this section by adding citations to reliable sources. Unsourced material may be challenged and removed. (March 2015) (Learn how and when to remove this template message) Vacuum washing employs a washhead that sprays water without detergent and immediately removes it by suction, creating a swirl of water. This ensures high cleaning performance, extracting the dirt from the carpet to a depth of half inch. By immediately reabsorbing the wash water, the drying time greatly shortened. This method is suitable for intermediate and basic cleaning. Because it does not require cleaning products, it leaves no detergent residue. Vacuum washing has long been in use in Europe, mostly in larger train and bus companies, schools, and historic preservation. The system works on all surfaces which are water resistant (carpet, upholstered furniture, wooden floors, stone, plastics). A great advantage is that this system works without brushes or pads so there is no abrasion on pile. Household processes Other household carpet-cleaning processes are much older than industry standardization, and have varying degrees of effectiveness as supplements to the more thorough cleaning methods accepted in the industry. Vacuum For more details on this topic, see Vacuum cleaner. Vacuum cleaners use air pumps to create partial vacuums to suck up dust and dirt, usually from floors and carpets. Filtering systems or cyclones collect dirt for later disposal. Modern carpet cleaning equipment use rotary vacuum heads and spray jets to deep clean the carpet through hundreds of multi-directional cleaning passes. Some add steam and agitation. Models include upright (dirty-air and clean-air), canister and backpack, wet-dry and pneumatic, and other varieties. Robotic vacuum cleaners have recently become available. Stain removal Cleaned and uncleaned areas of a carpet Tea leaves and cut grass were formerly common for floor cleaning, to collect dust from carpets, albeit with risks of stains. Ink was removed with lemon or with oxalic acid and hartshorn; oil with white bread or with pipe clay; grease fats with turpentine; ox gall and naphtha were also general cleaners. Ammonia and chloroform were recommended for acid discoloration. Benzine and alum were suggested for removing insects; diatomaceous earth and material similar to cat litter are still common for removing infestations. Candle wax is removed by placing a towel over the affected carpet area and applying steam from a clothes iron until the wax absorbs into the towel. Some traditional methods of stain removal remain successful and ecological. Caution should be addressed when treating natural fibers such as wool. The longer the stain material remains in the carpet, the higher the chance of permanent color change, even if all the original stain material is removed. At times pets urinate on the carpet and this results in a bad odor especially when it is hot and humid.The carpet or rug is usually taken outside and immersed in water to remove such stains. Immediately blotting (not rubbing) the stain material as soon as possible will help reduce the chances of permanent color change. Artificial food coloring stains are generally considered permanent stains. These may be removed by professional cleaners or deep cleaning rental machines with heat-transfer stain-reducing chemicals, but carry risks of burning the carpet. Stain removal products can be combined with anti-allergen treatments to kill house dust mites. Other Carpet rods, rattan rugbeaters, and carpet-beating machines for beating out dust, and also brooms, brushes, dustpans, and shaking and hanging were all carpet-cleaning methods of the 19th century; brooms particularly carry risks of wear. Steam cleaning increases the lifespan of your carpet. Misconceptions Robert Wittkamp (1942–2007), IICRC-certified master Carpet Cleaners technician with 30 years' expertise in carpet cleaning, commented that old wives' tales persist and thrive within the industry. For instance, the concept that walking barefoot on a carpet may lead to damage from body oils has not been supported or disproven by standardized reports or testing or by industry evidence.
