The IPC Eagle innovative Microfiber Tube String Mop is made from 100% microfiber fabric sewn into tubes to form the "yarn" of the mop. Because microfiber has millions of microscopic fibers, it picks up dirt and absorbs liquids far better than traditional mop yarn. An excellent choice for general purpose cleaning or spill pickup. As an added bonus, the wide headband is made of a rough scrubber cloth that can be used to remove dried-on dirt. Plus, we offer a three color coding system to prevent cross-contamination. It simply has the best performing string mop available. For use with narrow-band or wide-band style handles. The design of our Microfiber String Mop ensures even coverage without tangling during use or the laundering process. Machine washable.
