The Rubbermaid Commercial Trapper Dust Mop is constructed of a blend of post-industrial four-ply cotton and synthetic fibers for better durability and dust retention. This mop is made with looped ends that resist fraying and withstand laundering better than cut ends. The pre-treatment has a lemon fragrance, and lasts for 1 to 3 months. The synthetic fibers of this dust mop build a positive electrostatic charge from friction that attracts and retains dust.
