Review on 2-Pack of Nine Forty Industrial Cotton Dust Mop Head Refills, Commercial Grade, 24-inch Wide x 5-inch Size – Replacement for USA Floors by Jeff Kersey

I waited for a review until I washed a mop. I washed a few patch towels to see if they would tear or leave a lot of lint. Everything was good. I shook it out and hung it to dry. I haven't lost the thread. I didn't use bleach and I used cold water. It wasn't super dirty when I washed it. Next time I will try warm water and oxi wash. It fits perfectly. I wouldn't put the dryer inside as it can get a bit tight when putting it back on and could crack the blue backing. So it was nice to have another one while this one dries. The fibers are not nylon microfiber. Ideal for tiles and wood. I haven't tried it on a concrete floor yet.
