There is a franchise carpet cleaning company claiming that it does not pre-spray and does not add any cleaning products to their solutions because they believe that the use of any cleaning products will leave residue on the carpet fibers. Hot-water only may be acceptable when the carpeting is lightly soiled but when the carpets are heavily-soiled satisfactory results can not be achieved using hot water alone. They also claim that they use a special type of water and imply that this “special water” is all they need to clean all carpeting. Since the advent of the hot-solution extraction method, achieving residue-free carpet cleanings is easily done for any carpet cleaner that understands the process, has the most up-to-date equipment, and uses the best cleaning products. Aavalon has never had a problem with residue even though in the past 28 years we have completed thousands of heavily-soiled carpet jobs. This is because (1) Aavalon utilizes Motorized Jet-Extraction technology and never wands (2) we only use non-residue producing, all-natural products in normal situations (3) we have powerful In-truck and Portable extraction systems that remove approximately 90% of the solution.
