carpet cleaning service
One of the major problems in UAE is the prevalence of dust so The dust accumulates on all surface thereby causing indoor air pollution. The problem is aggravated if you have a surface that traps dust like carpet and rugs. For people with asthma and other respiratory problems, this can pose a serious challenge. Hence, regular carpet cleaning is of utmost importance if you are to maintain a good quality of air inside the house.
For appearance, and the removal of stains, dirt, and allergens is done through several methods. Clean carpets are recognized by manufacturers as being more visually pleasing, potentially longer-lasting, and probably healthier than poorly maintained carpets.
Hot water extraction
Although there is an actual steam cleaning industrial process, in the context of carpet cleaning, “steam cleaning” is often mistaken for hot water soil extraction cleaning, which is professionally known as HWE. The hot water soil extraction cleaning method uses equipment that sprays heated water and detergent on the carpet and simultaneously, the water and detergent is extracted, 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. Woven carpets can shrink but most carpets are not woven and are in fact tuffed on a laminate backing, velvet-piled carpets and Berber carpets may become fuzzy which is known as pile burst. Most problems can be avoided by professional experienced cleaners.
Hot water extraction equipment may be a portable unit that plugs into an electrical outlet, or a truck mount carpet cleaner 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 carpet cleaning 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 woollen 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 (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.
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/or outdoor ventilation.
Older surfaces, such as double jute-backed carpets and loose rugs with natural foundation yarns, could shrink after a wet treatment, leading to suppositions that wet-cleaning could also remove wrinkles. However, this notion is antiquated and this method could also occasionally tear seams or uproot strips. Newer carpets, such as with synthetic backing and foundation yarns, do not shrink, and they smooth easily; in such carpets, wrinkles indicate an underlying problem, such as delamination where the secondary backing becomes unstuck from the primary backing, that may need a certified carpet inspector to determine.
Wet-cleaning systems naturally require drying time, which may lead to concerns about very slow drying, the risk of soiling returning during drying as the moisture evaporates bringing the soils from deeper within the pile to the surface, as well as odors, bacteria, fungi, molds, and mildews. Carpet cleaning specialists try to find a balance between rapid drying (attributable to lower flow rate through the cleaning jets of a spray system) and the need to remove the most soil (attributable to higher flow rate).
Pretreatments similar to those in dry-cleaning and “very low moisture” systems are employed, but require a longer dwell time of 15 to 20 minutes, because of lower amounts of carpet agitation. Ideal pretreatments should rinse easily and leave dry, powdery, or crystalline residue that can be flushed without contributing to re-soiling.
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/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. The solution may add a solvent like d-limonene, petroleum byproducts, glycol ethers, or butyl agents. 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. 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.
A 98% biodegradable or others, slightly moist absorbent cleaning compound may be spread evenly over carpet and brushed or scrubbed in. For small areas, a household hand brush can work such a compound into carpet pile; working like “tiny sponges”, the attracted cleaning solution dissolve dirt, dirt and grime is attracted/absorbed to the compound, after a short drying time (the cleaning solution which is attracted to the compound must evaporate), it will be removed with a vacuum cleaner, the drier the better, leaving carpet immediately clean and dry. But it’s very difficult to remove all residues, the residues can cause allergies and biological compounds may cause discolourations on carpets. For commercial applications, a specially designed cylindrical counter-rotating brushing system is used, without a vacuum cleaner. Machine scrubbing is more typical, in that hand scrubbing generally cleans only the top third of carpet.
In the 1990s, new polymers began literally encapsulating (crystallizing) soil particles into dry residues on contact. In the conventional cleaning process surfactant molecules attach themselves to oily soil particles, suspending them (emulsification) so that they can be easily rinsed away. Surfactant (detergent) molecules and emulsified soils which escape being rinsed away, remain in the fibre and continue to attract soiling. Encapsulators are specialty detergent polymers which become part of the detergent system. As drying occurs (20-30 min. drytime), after cleaning, these encapsulation 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. Products which also employ fluorochemical technology, display dramatically extended anti re-soiling time periods. Cleaning solution is applied by rotary machine, brush applicator, or compression sprayer. Dry residue is vacuum-able immediately (20-30 min. dry-time), either separately or from a built-in unit of the cleaning-system machine.
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 special 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. A small amount of water is required with spin-bonnet carpet cleaning. It only cleans the top of the carpet 1/8 inch but it is very fast for wide areas. However, bonnet cleaning is not the best mechanism for completely removing the chemical that is pre-sprayed onto a carpet. It is recommended that only surfactant free or encapsulating products are used.
