For dry or wet use - these are 24 Inch CleanAide® Coral Weave Microfiber Mop Pads with Poly Strip, available in four vibrant colors: blue, red, yellow, and green. Use them dry to collect dirt and dust. When used wet, the Polyacrylonitrile stripes remove dirt, grime, and smudges from hard surfaces. CleanAide® mop pads don't require the use of chemicals, resulting in an eco-friendly cleaning experience. Durable and resilient, these pads can be washed and reused with no problems or loss of cleaning power. Easily and firmly attach to any 24 Inch mop plate using a hook and loop system, but best used with a CleanAide® 24 Inch aluminum mop plate, sold separately.
