Frequently Asked Questions - Wet V Dry

Why should I clean carpets using Host instead of a wet method?

What system will produce the best results! First, it is important to know the objective of carpet cleaning. Naturally, the key objective is to remove soil efficiently and as safely as possible.

There are two different principles at work in each method. A wet method must first liquefy and dissolve the soil in and on the carpet in order to begin to retrieve it. As the liquid flows onto the carpet liquefaction of the soil occurs. If the liquid is not removed immediately the liquefied soil can penetrate into the carpet backing and underlay. As the carpet dries out some of the soil and spills can wick back to the surface and the carpet will require re-cleaning.

Host works on a different principle. It uses millions of small sponges, dampened with the right amount of water, detergent and a safe-to-use organic material. This allows us to keep control of the liquids at all times during the cleaning process so there is no chance of wick back (stains coming back) or the risk soaking wet carpet.

Host works just like a sponge you use in your kitchen to wipe up spills on a table or counter. When you pass the sponge across the surface it lays out a film of cleaning agent which dissolves and absorbs the soil at the same time. This safe and controlled way of removing dirt meets with the same objective when using Host.

Why do carpets stay cleaner longer when dry cleaned with Host?

Carpets will not rapidly resoil as they do when cleaned with wet methods because after cleaning there is no sticky wet cleaning chemical residue left in the carpet that can grab and hold onto fresh soil.

What system would my customers prefer me to use?

Given the choice - your customers would most certainly prefer you to use the Host environment friendly dry carpet deep cleaning system. Why would any one choose an old fashioned energy inefficient, chemical spraying, water guzzling wet cleaning system that leaves carpets wet for hours!

What other types of carpet cleaning systems are there on the market?

There are four other methods available for cleaning carpets. However, none of them can compare to the benefits of using Host.

Hot Water Extraction (Steam) Method:

This method is occasionally called steam cleaning. Areas of heavy use are pre-conditioned with a strong alkaline chemical spray to help remove ground-in soil then a heated pressurised cleaning solution is injected into the carpet pile. The soil and chemical solution is then extracted and the carpet is left to dry. If the carpet becomes too wet, hot air blowers are installed to help speed up the drying time. The main disadvantage of this system is over-wetting and carpets are often left wet for several hours. Shrinkage and dye bleed are common factors with hot water extraction, even when the system is paced in the hands of a professional cleaner.

Rotary Pad (Bonnet Cleaning) Method:

The rotary bonnet method uses a machine similar to a floor buffer with an absorbent spin pad attached to the base of the machine. The carpet is sprayed with cleaning detergent and the spin pad absorbs soil as it rotates. When the pad is full of dirt, the pad is removed from the buffer and a fresh pad is put on the machine or the pad is rinsed in a bucket of water, drained then put back on the machine. The disadvantage of this system is pile distortion and transferring soil from one part of the carpet to another. Another disadvantage is the operator has virtually no control over the amount of cleaning detergent being used, rapid re-soiling often occurs directly after cleaning.

Dry Foam Method:

The dry foam method uses a high alkalinity detergent solution which is whipped into foam and applied to the carpet. The foam is then aggressively worked into the carpet with a scrubbing machine fitted with reel-type brushes. Some machines have inbuilt extraction capabilities whilst others need thorough vacuuming after the carpet is dry. The disadvantage of this system is over wetting, long drying times and the possibilities of pile distortion and shrinkage. Rapid resoling is a common problem as there is no proper means of extracting the detergent from the carpet.

Rotary Brush Method:

Cleaning detergent is injected into the carpet pile then a machine with rotating brushes is used to scrub the carpet fibres, the wet soil from the carpet is brushed out and collected into a small tray attached to the bottom of the machine, the carpet is then left to dry. This machine is predominately designed for cleaning hard floor coverings, when used on carpet it can cause pile distortion or untwisting of fibre. With no proper means of vacuum extraction over wetting and long drying periods are common which can lead to shrinkage and rapid resoling.

Is it true that Host uses less than one teaspoon of water per square meter of carpet?

Host uses very little moisture during the cleaning process - less than 1 teaspoon of water per square meter of carpet. Wet cleaning methods can use anywhere from 30 to 200 times that amount. Host uses just enough moisture to dissolve the soil but not enough to get the carpet wet. That means no over wetting, no shrinkage, no re-soiling and no mould growth. Therefore, not only will Host produce outstanding results, Host uses 97% less moisture than any other carpet cleaning system on the market.

Why do carpets get dirty quicker after being wet cleaned?

Based on statistics that manufacturers of wet cleaning systems use only 60-85% of liquid can be retrieved from the carpet after wet cleaning. Consequently, if 10 gallons of liquid is used in a room, 3-4 gallons of liquid will be left behind. When we look in the waste tank of the machine and see dirty water, we must remember the 3-4 gallons left in the carpet contains the same dirty water and cleaning chemical.

Carpets may appear to look clean after being wet cleaned but the truth is the carpet has just been heavily impregnated with copious amounts of water and sticky detergent. Dirt from daily foot traffic is quickly attracted by cleaning residue left in the carpet that will rapidly re-soil the surface at an alarming rate.

Evidence of a carpets re-soiling is often noticeable within just a few days after wet cleaning, brown or grey patches or streaks in walkways and entrances are the usual signs. However, the problem can be resolved by regular cleaning with Host. Host does not contain any un-natural detergents or sticky wet cleaning chemicals, so carpets will not re-soil and stains will not come back.

Cleaning and Support Services Association (environment agency - public briefing)

Did you know that it’s illegal to empty a bucket of used cleaning solution into a surface water drainage system or down a toilet? Watercourse pollution is taken very seriously by the Environment Agency. In 2006, a cleaning company was fined £40,000 with £33,000 costs for a single incident that severely damaged a watercourse.

When using Host you don’t have to worry about polluting the environment. Host is made from 100% natural ingredients; Host is fully biodegradable and can be safely disposed of by placing into a normal refuse bin, and because Host is biodegradable, it can be composted and recycled into reusable organic matter.

Can wet cleaning cause mould growth and allergens in carpet?

If a carpet becomes excessively wet during cleaning it’s very likely the cleaning solution will penetrate into the carpet backing and underlay. If too much moisture is left in the carpet, mould growth could form within just 24-48 hours.

Trapped moisture between layers of carpet and underlay make an ideal breeding ground for mould spores, and because the problem is hidden under the carpet, mould growth often goes undetected. Signs of mould growth are usually indicated by a damp musty odour in the air, by then it’s probably too late and the carpet may have to be replaced.

The dangers of mould growth

Moulds produce allergens, which are substances that can cause allergic reactions, as well as irritants and, in some cases, potentially toxic substances known as mycotoxins.  Inhaling or touching mould or mould spores may cause allergic reactions in sensitive individuals. Allergic responses include hay fever type symptoms, such as sneezing, runny nose, red eyes, and skin rash (dermatitis). Allergic reactions to mould are common, Moulds can also trigger asthma attacks in people with asthma who are allergic to mould.  In addition, mould exposure can irritate the eyes, skin, nose, throat and lungs of both mould-allergic and non-allergic people.
