The HOST® Aridex is designed for professional cleaners who clean upholstery in homes and offices, movie theaters and auto, bus, trains, subway cars and private airplane interiors. Safely clean most upholstery fabrics and leather furniture quickly and easily, never any shrinkage or sticky residue. The Aridex machine and detergent work together to create a special dry foam, which is worked onto fabric surfaces with a counter-rotating brush action that agitates the foam while stabilizing the fabric. Dry foam encapsulates the dirt and are removed by vacuuming.
