Pledge Grab-It Cloths use an electrostatic charge to attract dirt, dust and hair, which then get trapped in a web of specially designed fibers. Use the cloths alone or with the Pledge Grab-It Sweeper. When done, simply throw the cloths away. Disposable cloths contain no sprays or polish, so they don't leave a residue. Cloths are safe on wood, ceramic, vinyl and most other hard surfaces.
