While you are spoilt for choices when selecting carpet cleaning company for your home or business, it is important to understand the different types of carpet cleaning methods used by different companies as not all methods work for your carpet. Carpet Cleaning
Here are the types of carpet cleaning in the market:
Hot Water Extraction Cleaning
Commonly known as steam carpet cleaning, hot water extraction cleaning use high pressured hot water to agitate the carpet fibre and dissolve dirt in the carpet.
Hot water extraction cleaning typically involves application of cleaning agent on soiled surface, agitation of carpet with brush and followed by rinsing. After cleaning agent settle in the carpet for a short duration, the carpet will be “washed” by a carpet cleaning equipment to rinse the cleaning agent thoroughly and finally left to dry in room or air conditioned temperature
An average sized carpeted office of 3000 sq ft would normally take about 2 hours to clean and will take at least 4 hours to dry. Most companies would advise carpet to be cleaned in the late afternoon so that after it is done, the carpet can be left to dry over night and office operation can resume back to normal the next morning.
Shampoo carpet cleaning was popular till encapsulation technology was introduced in 1970s. While shampooing it may seem to clean heavily soiled carpet, the technology’s disadvantage – leaving behind high amount of wet foam residues in the carpet that takes a long time to dry, becomes sticky when it dries because no rinsing is done after shampooing and rapid re-soiling of carpet – makes this method less popular than others.
Foam encapsulation use synthetic detergents as a base that will crystallize into powder form when dries. Loosened dirt particles in carpet fibre will be encapsulated into powder when the applied cleaning foam dries and, finally, vacuumed or brushed when the foam dries after cleaning.
The foam encapsulation cleaning technique has overtaken carpet shampooing technology as the former uses less water during cleaning which result in shorter drying time compared to the carpet shampooing. The foam encapsulation cleaning has received thumbs up by those who advocate using of environmental friendly products because there is less chemical residue left behind after cleaning compared to carpet shampooing.
