What is the difference between steam cleaning and the shampoo method?
A. Steam cleaning, or hot water extraction, consists of heated water mixed with cleaning solutions which is injected into the carpet under pressure to liquefy the soil. The solution and the soil is then immediately extracted from the carpet. The shampoo method is a surface cleaning using detergents applied with a rotary machine. The problem with shampooing is that it leaves a soap residue which attracts more dirt. In addition, it can damage the fibers.
