Hot water steam: (The Pure Floor Care Method) Your carpet is pre-conditioned with a solution to first loosen the soil and then a hot water rinse is applied under pressure to extract or “vacuum” out the unwanted pollutants.
In a recent Technical Bulletin, Shaw Industries, the world’s largest carpet manufacturer, recommends the hot water extraction system. Shaw Industries research indicates, hot water steam extraction provides the best capability for cleaning carpet.
You can choose from two different types of hot water extraction: Truck mounted extraction, which is done with a large machine mounted in a truck or van. Or portable extraction, which is done with a small, hand held unit. Truck-mounted hot water extraction is by far the most thorough and effective method. HOT WATER STEAM IS MOST EFFECTIVE
Absorbent pad (bonnet cleaning): This method is similar to dry foam, except that the technician uses a floor polishing machine set on top of a cotton bonnet which “buffs” the carpet in a rotating motion. This rotating motion causes the bonnet to absorb dirt from your carpet. This method is also called bonnet cleaning. Bonnet cleaning is like trying to use a large cotton towel or mop to rub the dirt out of your carpet. IT IS NOT AS EFFECTIVE!
Dry foam: The carpet cleaner applies shampoo to your carpet, allows it to dry, and then, without rinsing, extracts the dried shampoo into a vacuum. Can you imagine applying shampoo to your hair, allowing it to dry and then removing the shampoo from your head with a vacuum? This method leaves dirty residue in your carpet, which attracts more soil, DRY FOAM IS NOT VERY EFFECTIVE.
Absorbent powder: This method uses a moist compound which is spread onto your carpet fibers. This absorbent compound is allowed to dry and then is vacuumed off. This method leaves dry sponge-like particles at the base of the carpet yarn. And because the carpet is not rinsed, will re-soil quickly. THIS METHOD IS NOT EFFECTIVE!
