The tile also has little pit holes in it to that the dirt just gets in and sticks as well as along the grove lines. This is in a high traffic area so it is dirty nightly. I started cleaning with a scrub brush and then moved to a handled angled brush to get in the crevices better, but it takes forever and it never looks absolutely clean.
