Carpet Doctors employs hot water extraction, also known as steam cleaning.
This method consists of a hot water cleaning solution, under high pressure, being sprayed into your carpet and then quickly extracted back out of the carpet with a high power vacuum system. This breaks up the dirt, bacteria, dust mites feces, pollens and pollutants, allowing them to be extracted from your carpet using high suction.
Not only does this method cleans your carpet better, but it also kills most germs and bacteria due to the use of high temp water. As a matter of fact, Shaw Industries, the worlds largest carpet manufacturer, recommends hot water extraction as the primary method of cleaning carpets in order to maintain warranty coverage.
