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 an 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

Also known as ‘Steam Carpet Cleaning’ among the professionals, the process utilises high-pressure hot water to agitate the fibres and threads of the carpet to allow for dirt to be efficiently dissolved. Usually, cleaning agents will also be added onto the soiled surfaces for just a short period. before a thorough rinse to wash off all the cleaning agents. Finally, the carpet is left to be air-dried and is ready for use in no time.

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.

Hot Water Extraction Cleaning

For the average-sized carpeted offices of roughly 3000 sq ft, the Steam Carpet Cleaning method is ideal due to the amount of time it takes. After approximately 2 hours of cleaning, it then takes another 4 to 6 hours for the carpet to dry, which can be done overnight after everyone has knocked off from work.

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 the shampooing method would face similar consequence if carpet rinsing is not done thoroughly.

Before encapsulation technology for carpets came about in the 70s, shampoo cleaning was the most relied upon when cleaning our carpets. 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

The Bonnet Cleaning method produces great results as it utilises a heavy-duty motorised machine that cleans the surface of the carpet fibres. Its reliability is further emphasised with a cleaning solution that effectively absorbs dirt from the carpet.

Bonnet Cleaning

The Bonnet method is widely used in many hotels as it serves to be a quick and fuss-free solution to clean carpets where many step foot on, 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.

One downside to the bonnet method however, is its inability to deep clean carpets, allowing dirt beneath the carpet to emerge back to the surface quickly. Due to the pressure caused by the spinning pads, bonneting may also cause the accumulation of chemical residue on the base of the carpet.

Dry Carpet Cleaning

Dry carpet cleaning, also referred to as the compound cleaning method has garnered massive popularity and attention, even gaining the approval of leading carpet manufacturers due to its impressive result and convenience it provides.

Not only does this method clean thoroughly, one of the biggest takeaways from this method is it does not require drying time.


As it was invented in the 80s, the dry cleaning method is still known to be a fresh and new technology, which has led to many doubting its effectiveness when compared to the other methods of carpet cleaning which process have taken much longer.

The key benefit of this method lies in its use of the cleaning compounds or powder that penetrates into the base of the carpet using a motorised counter rotating brush which allows these compounds to settle and deeply clean the carpet.

Typically made of biodegradable materials, these micro-sponge-like compounds effectively absorb dissolved dirt which can easily be vacuumed out at the end for a freshly cleaned carpet.

Different manufacturers of dry cleaning equipment develop their own formula for the cleaning compounds and power and even customise the design of their equipment to differentiate themselves.

As the dry carpet cleaning process is suitable for all types of carpets and does not disrupt business operations at any time of the day, it’s a recommended method for commercial offices, homes or any other spaces that involves heavy foot traffic.
