Scrub floor tile with these.  Eeeew! Effective!
I used these to scrub a tile Floor that has been in place for 10 Years.  The floor<br />Is washed religiously every 2 weeks but even so, going hands and knees with these took off a bunch of invisible dirt.  People say they do. Good job on grout too but i tried in a bathroom that had a bit of that pinkish residue on the grout and it didn’t seem to help much.
