In addition to regular vacuuming, DIY cleaning is usually insufficient in removing deeply-embedded dirt, as well as harmful bacteria that can cause respiratory ailments. Therefore, it is best to get your carpet professionally cleaned at least twice a year.

Now, let’s learn about the different methods of carpet cleaning used by professional carpet cleaning companies. While it’s true that the carpet companies are professionals in the trade, it still helps to know what cleaning methods work best to clean your carpet so that you may get the best mileage from your carpet. Here are the five methods of carpet cleaning commonly used by professional cleaning companies:

1. Hot water extraction cleaning
Also known as steam carpet cleaning, this cleaning method uses high-pressured hot water to agitate the carpet fibre and dissolve the dirt trapped in the carpet. This method of cleaning also involves the application of a cleaning agent on the soiled surface, followed by the agitation of the carpet using a brush before rinsing.


2. Carpet shampooing
Carpet shampooing is by far the longest-lasting method when it comes to carpet cleaning. In this process, the carpet is cleaned with a wet shampoo that is formulated with coconut oil spat and scrubbed using a rotary machine, followed by a thorough wet vacuuming to remove the grit from a heavily soiled carpet. The only downside to this method is that it will take longer for the carpet to dry.


3. Encapsulation
Carpet cleaning using the foam encapsulation method utilizes synthetic detergents as the base that crystallizes into powder form once it dries. So far, this cleaning technique has overtaken carpet shampooing, as it uses less water, hence, requires shorter drying time. This method also leaves behind less chemical residue after every cleaning. After the application of the chemical detergent, the carpet is then vacuumed to get rid of the dust, dirt and detergent residues.

4. Dry extraction cleaning
The dry extraction cleaning method is reliable, effective and time-saving and sustainable, as it doesn’t use water. In this method, the cleaning powder is sprinkled into the bottom part of the carpet using a rotating brush machine. This works to open up the carpet fibre, letting the powder to settle inside to allow deep carpet cleaning. The carpet is then vacuumed to remove soil and combined powder.

This method is best used for commercial installation where the floor covering needs to be cleaned regularly and requires instant drying.


5. Bonnet cleaning
Mainly used for commercial buildings, this cleaning method may not be super effective in removing germs, but it will keep the carpets looking fresh and clean without thoroughly cleaning the dirt and dust that are trapped under the carpet surface. In the bonnet cleaning method, a chemical detergent is applied to the carpet and then a rotary machine, equipped with an absorbent pad, is then worked across the carpet to clean it.
