The Most Comprehensive Carpet Cleaning Guide: Singapore 2021

We tend to forget that the carpets at home or in the office, can often affect the air quality.

For example, dirty carpets with excessive dust particles trapped between carpet fibres can rise into the air we breathe when we walk on it – and we breathe in these dust particles. Besides airborne particles, microorganisms like bacteria, dust mites, mould and fungi also thrive in the warm and humid carpet.

Regular carpet cleaning not only helps to prolong a carpet’s lifespan, but regular professional carpet cleaning service also maintains the quality of the air we breathe. So keeping your carpet clean is important.

Carpet cleaning in Singapore

While many people vacuum their carpets or wipe off surface soiling to maintain carpet cleanliness, these methods are sufficient for day to day maintenance but are not enough to remove microorganisms like dust mites and bacteria.

Dust mites and other microorganisms are not so easily rooted out by just vacuuming and surface cleaning. They often reside deep in the fibres of the carpet material and it takes deep cleaning methods to really flush them out.

It also takes a relative humidity (RH) of 60% or more for microorganisms to grow, and in Singapore, it has a RH of between 60% in the mid-afternoon, to about 90% in the morning – making it an ideal place for bacteria and other microorganisms to multiply.

That is why cleaning it the right way is important, because you do not want to damage the carpet or the environment while doing so.

So how do I deep clean my carpet?

There are many solutions on how to clean carpets yourself. But DIY methods using home remedies often involve investing a lot more time, while results often vary; with some cases even making the carpet smell worse after cleaning.

While you can attempt to wash smaller ones on your own, bigger carpets and carpeted floors, such as those in the office, would often be better off with professional carpet cleaners.

There are many questions when it comes to professional carpet cleaning. Do professional carpet cleaners vacuum first? How soon can you walk on the carpet after cleaning? How long do professionally cleaned carpets take to dry? What is the safest carpet cleaning method? What is the best method for cleaning carpets? Is it worth getting carpets professionally cleaned? Is it better to shampoo or steam clean carpets? Do carpets get dirty faster after cleaning? And many other questions.

So let us look for the answers to these questions by studying the methods used by professional carpet cleaners.

Hot Water Extraction Cleaning

This is also commonly known as steam carpet cleaning. High pressured hot water is used to agitate the carpet fibre and dissolve dirt in the carpet. It typically involves the application of cleaning agents on soiled surfaces, agitating the carpet with a brush followed by rinsing.

After the cleaning agent is settled in the carpet for a short duration of time, the carpet is “washed” by carpet cleaning equipment to rinse the cleaning agent thoroughly. The carpet is finally left to dry in room or air-conditioned temperatures.

This method works well for average-sized carpeted offices of 3000 sq ft, and would normally take about 2 hours to clean. It will then take another 4 to 6 hours to dry. Because of the time it takes, most cleaning companies would advise that the carpets be cleaned in the late afternoon so that the carpet can be left to dry overnight and office operations can resume the next morning.

Carpet Shampooing

If you do not rinse your hair thoroughly after shampooing, your hair would feel uncomfortably “sticky” when your wet hair has dried. Carpets cleaned by shampooing method would face similar consequence if carpet rinsing is not done thoroughly.

Shampoo carpet cleaning was a popular method until the introduction of encapsulation technology in the 1970s. Shampooing of carpets often seems to be able to clean heavily soiled carpets, giving the impression the carpet is thoroughly cleaned.

However, carpet shampooing often leaves high amounts of wet foam residue in the carpet due to insufficient rinsing. Because of this, it gives the carpet a “sticky” feel, eventually causing the carpet to be re-soiled quickly.


This method is very similar to shampooing as it relies on the aggressiveness of the brushing action, which is usually counter-rotating cylindrical brushes. The only difference is that the solution is pumped into foam and applied on the carpet before the brushing process, instead of using liquid shampoo. Thus, the carpet cleaner would use 80% less liquid than conventional carpet shampoo.

The revolution of foam encapsulation or dry foam method is the synthetic detergents used as the main cleaning ingredient, that will crystallize into powder form when it dries. The loose dirt particles in the carpet fibre will be encapsulated into powder when the applied cleaning foam dries and, finally, this powder is vacuumed or brushed away at the end of the cleaning process.

This technique has become more popular than carpet shampooing technology as it uses less water during the cleaning process. This results in shorter drying time when compared to carpet shampooing.

It can also be used with environmental-friendly products which produce less chemical residue after cleaning compared to carpet shampooing.

Although it has shown good cleaning results, this method only removes average levels of soiling, and there is a possibility of excessive residue and soil build up if the machine being used has inadequate extraction capabilities.

Bonnet Cleaning

This carpet cleaning method produces good surface cleaning results as the process mainly involves cleaning the top part of the carpet fibre using a heavy-duty motorised machine with a spinning pad that has been immersed with cleaning solution. This helps it to absorb dirt from the carpet surface effectively.

Bonneting is popular in hotels because it provides a quick fix solution to having a clean carpet in heavy foot traffic areas, such as the reception, corridor and other public spaces. Carpets in such heavy footprint areas need to be cleaned without much moisture so they can dry quickly.

Because bonneting does not deep clean carpets, dirt beneath the carpet would emerge back to the surface within a short period of time, causing carpets to get soiled again quickly.

Bonneting also tends to cause accumulation of chemical residue in the carpet as pressure from the spinning pads tend to push the applied chemical and excess dirt into the carpet base.

Dry Carpet Cleaning

Dry carpet cleaning or compound cleaning is one of the latest cleaning technologies found in the market. It is gaining popularity and has the approval of leading carpet manufacturers because of its effective cleaning performance and convenience. Not only dry carpet cleaning cleans thoroughly, one of the biggest takeaways from this method is it does not require drying time.

Dry carpet cleaning technology was invented in the 1980s, offering many types of cleaning compounds or powders that have been developed in Western countries. As this cleaning technology is considered relatively new compared to other conventional wet carpet cleaning methods which have been trusted and used for decades, many still doubt the effectiveness of this cleaning technology.

The highlight of dry carpet cleaning is the application of its cleaning compound or powder into the bottom part of carpet using a motorized counter rotating brush machine. This machine helps to open up the carpet fibre, which then allows the compound to settle deep inside the carpet. This results in a thoroughly deep cleaned carpet.

The cleaning compound is typically made of biodegradable materials that work like micro-micro-sponges. They effectively absorb dissolved dirt in the carpet and can be removed thoroughly at the end of the cleaning process through vacuuming.

Different dry carpet cleaning equipment manufacturers differentiate themselves by developing their own cleaning compound or powder formula and customizing their equipment design and function.

Dry carpet cleaning is safe and suitable for all carpet types. It is also recommended for commercial offices, homes and any space that has heavy foot traffic or operates on a 24-hour basis, because daily operations need not be disrupted during the carpet cleaning process.
