Question DetailsAsked on 9/21/2011

Please tell me about the effectiveness of the "Host Dry Cleaning System."

The "Host Dry Cleaning System" is said to be eco-friendly and more or just as effective as steam cleaning for carpets. Do you have any info about this either pro or con?

HOST cleaning has its place in the industry but is not the most effective method available. The major draw is fast dry times which is extremely desirable to most patrons.

Cleaning using the HOST method is done by scattering tiny, plant based absorbent sponges over the carpet. Then a scrubbing machine is used to agitate the matter into the carpet fibers while immediately extracting them with vacuum. The idea is that the sponges are so absorbent they will attract soil and residue and then be sucked out of the carpet with the soil and residue attached.

The HOST system does work and is effective on lightly soiled residential carpet and commercial carpet made from synthetic materials. Dry times are minimal--usually an hour or so. However, for moderately or heavily soiled carpet, or even some lightly soiled carpets that are very plush, the HOST system is not adequate. The best cleaning agent is water and often times there is no replacement. A system such as HOST that uses very small amounts of water is just not sufficient to remove a large soil load from most carpets.

Also, the major carpet manufacturers suggest steam cleaning, or Hot Water Extraction (HWE), as their recommended method. Many times HWE is also the only method allowed under warranty. You can see Shaw's recommendation here, and Mohawk's recommendation here. These are the two major carpet manufacturers and both suggest HWE.

As a final thought, please understand a good reputable HWE carpet cleaner will provide the best results and should still deliver relatively fast dry times. Often, home or business owners are reluctant to call for HWE because of bad experiences or they've heard horror stories. In reality the concientious cleaner is fair, reliable and well educated in his field, and views drying the carpet just as important as cleaning the carpet.

I have done the dry cleaning method for @ 10 years now.

And whereas I agree with most of the other person's detailed answer about how the dry system works there is, however, one thing that should be added regarding heavily soiled, thick carpet.

The most effective way to clean this type of carpet involves an extra step.

After the first step of vacuumung the carpet there is a second step that is added.

The carpet should be sprayed any place that is soiled with a 'prespray liquid' that is designed to be a carpet prespray for cleaning it.

Then the spray should be allowed to sit for @10 to 15 minutes. This allows for the liquid to breakdown the dirt, etc. which will in turn allow the product to work far better.

Then the product is applied to the carpet and 'scrubbed' by using the machine but w/o turning on the vacuum. As the 'scrubbing' is done one can see the product get darker as the carpet gets lighter.

The last step is to vacuum the product and check for places that might need a 2nd or even a 3rd cleaning. In spite of larger amounts of prespray being used on the carpet there is still only a 15 to 20 minute drying time because most of the extra liquid is absorbed by the product which is then vacuumed up with the dirt!

Another great feature about this system is the fact that there is no 'wicking effect'.

This is the effect where you might have spots that are from spilled drinks or pet urine, etc. Then once the carpet has been cleaned with the water system they appear to go away.

However 2 or 3 days later the spots return.

This is the result of the leftover water bringing remaining dirt with it as it travels up the strands and into the atmoshere as it evaporates. However it leaves the dirt with the carpet and alas the spot returns.
