Question

Why is dry carpet cleaning not discussed more? It seems to have all the positives no water, no mold, fast and efficient cleaning etc, so why is it not brought to the forefront in this forum?


Answer

Answer # 1.
No reason that I know of. Our experts answer question based on their experience, knowledge and preference. We avoid mentioning products by name or endorsing one process or approach over another.

Answer # 2.
Dry powders are really good for interim maintenance. They work exceptionally well on coffee stains. However, it is a good idea to clean carpet regularly by hot water extraction to ensure that the carpet is flushed out on a regular basis. Remember that carpet is like a sink; it always collects water, moisture and dirt.

Answer # 3:
The answer to the first question is that no one has asked specifically about it. Several interim cleaning methods are discussed by the IICRC S001, including absorbent compounds (“dry” cleaning), bonnet cleaning, dry foam, and others. Hot water extraction using a walk-behind automatic could be viewed as interim cleaning. All have pluses and minuses. Absorbent compounds are low moisture and reduce drying time, which can be an advantage, but the same may be said of dry foam and bonneting.
However, no water or low water is a plus only until you need to dissolve heavy accumulations of ice melt or detergent residue. To quickly rinse these out of fiber you need water as a solvent and often a considerable volume of it.
Mold growth is not the natural outcome of water based soil extraction. Low moisture methods other than absorbent compounds abound, and even the potential problems of heavy rinsing can be offset by proper wand or rinse head techniques followed by careful vacuuming. Bonnet cleaning will rival using absorbent compounds in speed of operation, with both taking an average of 70 minutes per 1000 sq. ft.
A self-contained, self-propelled extractor with a 16 inch path will cut the time to 30 minutes, much faster than either of the above. Rather than moving any one method to the forefront, ICAN recommends that a fiber cleaning system be chosen based on the needs and circumstances of the user, and that it be applied in harmony with the basic principles of cleaning.
