GO BIG! Like all of California Duster Company's mop heads, the 100% cotton strands of the Super Duster are coated with a paraffin wax treatment, which allows the duster to lift and remove dust, dirt, pollen, and lint like a magnet. Fibers are literally trapped within the strands, and removed by simply shaking out the duster. With the 9-1/2 x 17 oval 360° head, you will be able to clean a larger area in less time. Total duster length is 30" long.
