Micro Fiber Dust Mop fits a standard, 24" dust mop frame and handle. Poly/canvas-backed microfiber mops attract and hold dust that cotton mops leave behind. Envelope-style backing eliminates problems created by ties or snaps. Extra padding in mop allows complete surface contact. The mop attracts dust electrostatically and requires no treatment. 100 percent microfiber fringe picks up larger particles of dust and trash.
