Best 5 Types of Carpet Cleaning Methods Used by Companies


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.

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.

Carpet Shampooing

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.

Encapsulation

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.

Although this technique has shown good cleaning results, this cleaning method has not been able to thoroughly clean heavy soiling carpet because of the technology's limitation.

Bonnet Cleaning

This carpet cleaning produce good surface cleaning result as the process mainly involve cleaning the top part of the carpet fibre using a heavy duty motorized machine with a spinning pad that has been immersed with cleaning solution to absorb dirt from the carpet surface.

Bonneting is popular in hotels because it can give a quick fix solution to clean carpet in heavy traffic public area that require carpet to be cleaned without much moisture and can dry quickly to prevent causing inconvenience to hotel guests.

Because bonneting does not clean carpet deeply, dirt beneath the carpet would emerge back to the surface within short period of time, causing carpet to get soiled again quickly. Bonneting also tends to cause accumulation of chemical residue in the carpet as pressure from the heavy machine on the spinning pad push the applied chemical and remaining dirt into the carpet.
