Carpeting is a major investment in your home, and regular cleanings are necessary to keep it looking new. In fact, because it gathers in carpet fibers and erodes them, soil, not foot traffic, is the largest contributor to the premature demise of carpets. Regular carpet cleanings are so important that most major carpet manufacturers require them in order to maintain their warranty. Extraction Method Often called steam cleaning. Although temperatures vary with equipment, seldom does the temperature reach the boiling point. A water solution under pressure is injected deep into the carpet pile and then immediately vacuumed out into a holding tank along with the soil. This method flushes residual matter reducing the risk of resoiling. It is a well-known fact in this industry that major carpet manufacturers and fiber producers recommend hot water extraction.
