18" ultra Microfiber DXL-FLAT MOPS (12 PACK) EchoLine® MicroQber Wet Pads Microfiber products are made out of very fine microfiber filaments that clean better than common mops and cloths. These small fibers reach deeper into microscopic cracks and crevices to remove dirt, dust and grime. Ultra fine fibers trap the dirt and debris within the microfiber so it can be removed and disposed of. Surfaces are left clean and virtually streak free. They can be machined washed for extended uses.
