Ready-to-use. Swiffer helps get rid of dust and dirt! Swiffer's dry, disposable cloths use electrostatic action to pull particles and hair into the cloth, where the web of fibers traps them! Swiffer captures dirt, dust and hair contact, instead of just stirring them up! Safe for wood, ceramic, vinyl and laminate floors. Leaves no residue. Use for dusting above the floor. Great for picking up dust, dirt and hair. Do not add sprays or liquids. pgpro.com. Data rates apply. Questions? Call 1-800-332-7787; pgpro.com.
