Covering floor tiles
Mats and rugs are best companions of your slabs. They will protect them from grime and also soak the excess moisture from the surface. Put a good quality mat on the entrance and request your guests to wipe their footwear on the mat prior to stepping in. This exercise will remove all the grime from the footwear and thus prevent your slabs from the grime that your guests would otherwise carry with their footwear. Similarly, you can put rugs on the entrance of the bathroom. The rug will soak the moisture from your feet and thus prevent the slabs from the moisture.
Sweeping and vacuuming floor tiles
Take a soft bristles broom and sweep your slabs regularly at least twice in a day. Sweeping will remove the dirt from the slabs and make them look sparkling clean all the time. Vacuuming is also necessary but not regularly. You can vacuum clean the tiled floor once in a fortnight. You must be thinking that when sweeping can clean the slabs then where is the need to vacuum them. Sweeping takes particles that are visible but leaves very fine particles than can set on the surface if not taken away. Broom can't take away everything but vacuum can make a tiled floor look perfectly clean.
