Today's businesses and households have quite a few options for getting their carpets cleaned, though each method is different, giving varying results.
Today's carpet industry utilizes the following four prominent methods for carpet cleaning:
1. Von Schrader industrial machines, using shampoos
2. The Host method that makes use of a dry, eco-friendly absorbent cleaning mixture
3. Bonnet Cleaning – the method employed by the licensee Chem-Dry, using a mixture of carbonated water with exceptional cleaning mixture
4. Steam cleaning or hot water extraction, the method that most carpet manufacturers recommend
Here, we'll look at these four different methods of cleaning.
Popularly called the shampooing of carpets, it is an old way of cleaning carpets that most householders do not use anymore, though the method known as Schrader shampoo is still extensely employed by big casinos and hotels. This process employs s somewhat moist shampoo mixture that is administrated by rotary brushes and uses mild suction for the extraction of dirt. This technique involves no rinsing, as a result of which the residual may continue getting accumulated, despite cleaning. This leads many to wrongly conclude that the carpets get dirtier soon after their cleaning. As the industry started replacing soaps containing coconut oil by synthetic detergents, the treated shampoo got transformed into powder. As a result, the loosened dirt gets attached to the powder components and vacuuming is required in the following day to complete the cleaning process.
Dry compound – making use of a dry eco-friendly absorbent
In this method, a biodegradable cleaning compound, which is absorbent, is even spread over the carpet, which is brushed in or even scrubbed. For long, the material most often used as base was corn husk. It was only during the 1990s that husk was replaced by synthetic polymers for better effects. Homeowners having small carpets can use the common household brush for the purpose, resulting to the compound combining grime and dirt which can be vacuumed subquently to quickly get a dry and clean carpet. These days, scrubbing machines are used more often, as these machines are more powerful than the normal domestic vacuum cleaners.
Bonnet cleaning using carbonated water
In this method, the surface of carpet is covered with a mist that is formed using a mixture of carbonated water and cleaning products. This is followed by the scrubbing of the mixture using a 'bonnet' having a rotary motion. This kind of industrial machine is quite similar to a hard-surface floor buffer, which has an absorbent pad for attracting dirt. The pad needs to be rinsed or replaced repeatedly as it keeps getting dirty. Since the method makes use of carbonated water, it can not be called as dry cleaning of the carpet, and would ever require reasonable time for getting discharged. Moreover, the method is usually effective for cleaning the first third of the carpet's fibers from its top. Although Chem-Dry is the country's largest franchise employing this method, carpet manufacturers advice against using this method.
Steam cleaning or hot water extraction
This is the method most recommended by the carpet manufacturers. It makes use of an alkaline cleaning agent for pre-treating the carpet. Acid based cleaning agents are used for carpets with natural fibers. After its pre-treatment, it is rinsed to get rid of dirt. A wand, connected with a very powerful vacuum, removes the dirt and the cleaning agent. Agitators are used for removing the dirt. During the early 1990s, the introduction of powerful hot water extraction machines, mounted on a truck, has modernized the cleaning techniques. The use of modern technology employs for making highly powerful machines, capable of operating at high temperatures and the availability of detergents with better chemistry, has facilitated a safe and highly effective method of cleaning that most carpet manufacturers insist for keeping their warranty valid.
