Microfiber Wet/Dry Mop Pad Refills are thin, durable and effective. Woven microfiber picks up more dirt than nonwoven disposable pads. They are safe to use on all types of hard floors. Disposable design minimizes cross-contamination and is perfect for hospital wards, restrooms, gym/fitness studios or locker rooms. Reuse in safe zones such as corporate offices, living spaces, food-prep areas and dining spaces. They fit standard, 18" commercial mop frames and are compatible with Swiffer Sweeper, Swiffer WetJet and most home mops (none included). Innovative dispensing box dispenses one pad while priming the next pad for use.
