Hot water extraction is a method of carpet cleaning . It involves a combination of hot water and cleaning agents being injected into the fibers of the carpet at high pressure and all lifted soil being removed by 3 powerful vacuums. We use cleaning agents that are safe for the environment. Hot water extraction is usually preferred when a deep cleaning is necessary. Carpet manufacturers recommend that your carpets are cleaned by this method every 12-18 months to protect the warranty. It is the only way to get a true deep clean. We at Toney's Floor Care, LLC take pride in the fact that we use this method. Don't settle for anything less. Upholstery can really benefit from this type of cleaning. Using the hot water extraction method on indoor and outdoor upholstery guarantees the best removal of germs and dirt.
