WHICH METHOD CLEANS BEST?
Dry foam: The carpet cleaner applies shampoo to your carpet, allows it to dry, and then, without rinsing, sucks 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 a dirty residue in your carpet that causes it to re-soil quickly. This is the major reason that dry foam is not too effective.
Absorbent pad (bonnet cleaning): This method is similar to dry foam, except that the company sets a large cotton bonnet on your carpet. The rotating motion causes the bonnet to absorb dirt from your carpet. Bonnet cleaning is like trying to use a large cotton towel or mop to rub the dirt out of your carpet. It’s not very effective because there’s no extraction process. And if the bonnet isn’t changed out with a clean one frequently enough, it just smears soil around the carpet.
Dry, absorbent powder: The dry-compound method spreads a moist, absorbent powder throughout your carpet. The powder is allowed to dry and then sucked into a vacuum. This method leaves dry sponge particles at the base of the carpet yarn. And because the carpet is not rinsed, this method is not very effective.
Hot water extraction: This is a fancy way of saying that a hot water cleaning solution under high pressure is forced into your carpet and then drawn out of your carpet.In a recent Technical Bulletin, Shaw Industries, the world’s largest carpet manufacturer, “recommends the hot water extraction system, which research indicates provides the best capability for cleaning.”
No question, the most effective way to clean carpeting is with hot-water extraction truck mounted equipment. It’s the most powerful cleaning equipment on the market, and the only equipment that cleans your carpet of dirt, harmful bacteria, fungus, chemicals, pollens, and tobacco residue.Some people believe that hot water damages your carpet, but this isn’t true. By washing and then rinsing your carpet with hot water, we clean your carpet completely--in the same way that the person who showers and then rinses of the dirt and soap will be much cleaner than the person who takes only a sponge bath.
