Dry Fusion is the only carpet cleaning system that hot cleans, deodorises, stain protects then heat dries every type of carpet. It's all in the same process, and because it is patented, nobody else can use this amazing system of cleaning. By taking all the best features of hot water extraction (hot solution, "Shot of Steam"), the best features of dry cleaning (low moisture, mechanical agitation) combining them together with the patented hot cleaning pad system that constantly heats the fibres as they are being cleaned - you have some of the most outstanding results ever seen. Two unique mechanisms work to keep Dry Fusion cleaned carpet virtually stain free to maintain that just cleaned look longer. A Fluorocarbon Resin (a Dupont Specialty) places an invisible protective shield over every fibre during the cleaning process. It helps prevent dry grit, dust as well as spills lodging within the carpet. Even walked in mud and oily spills have difficulty seeping in. Because the fibre is effectively "non stick" when you DRY FUSION clean, vacuuming removes more soil, plus the vacuum cleaner is easier to push, Carpets Dry In 30 Minutes Guaranteed.
