DO’S AND DON’TS OF CERAMIC TILE CARE
Do not combine ammonia and household bleaches.
Do not use harsh cleaning agents (such as steel wool pads) which can scratch or damage the surface of your tile.
Do not use a cleaning agent that contains color on unglazed tile. It has a relatively porous body and may absorb the color.
Do test scouring powders in a small area before using on tile.
Do use a silicone sealer on grout joints if continuous staining is a problem.
Do read and follow label directions for all cleaners.
