Clean your tile & grout using warm water and a clean nonabrasive cloth sponge or mop. Use a neutral cleaner that is specially formulated for ceramic, porcelain tile & grout to help remove soils that sweeping, dusting, vacuuming or damp mopping leave behind.

Do not use ordinary household cleaners, as you may degrade the sealer that was applied to the grout to protect against stains. This includes not using acidic or alkaline cleaners, bleach, abrasives or ammoniated cleaners.

Vacuum or dust frequently using a clean non-treated dry dust mop. Sand, dirt, and grit may scratch your tile or build-up on your grout joint leading to discoloration. Mats or area rugs inside and outside an entrance will help minimize the potential damage from these particles.

Damp mop your tile floor with a diluted solution of neutral cleaner. Try to stay off the floor until it is completely dry, as wet tile floors may be slippery.
 
GROUT CARE:
Once the tile has been cleaned and dried (shortly after installation) grout joints should be treated with a silicone sealer. Grout is porous and sealing it at this time will simplify maintenance in the future. (Epoxy grouts do not require a sealer). It is recommended that you apply a sealer at least twice a year for maximum stain protection.

Heavy duty cleaning:
Neglected or heavily trafficked tile may require more intensive cleaning. Glean glazed wall tiles with a scouring powder or all purpose cleaner applied to a non metallic pad. Rinse and wipe dry. For glazed floor tiles, use a commercial tile cleaner, or apply a strong solution of an all purpose, non oil based cleaner or scouring powder paste. Let stand for five minutes, brush and scrub. Then rinse with clean water and wipe dry.

For heavy duty cleaning of unglazed wall tiles, make a paste of scouring powder. Apply to surface and let stand for five minutes. Scour with brush, rinse and wipe dry. Unglazed floor tiles can be cleaned in the same manner. Though a small brush is suitable for most floors, you may want to use a scrubbing machine for large areas.

What to Do When Spills Occur:
Grout Etching
Ceramic and porcelain tile is usually impervious or highly resistant to staining. However, grout may be a different story. Substances that are highly acidic, such as orange juice, coffee, vinegar, wine, tomato-based products, mustard and many soft drinks will most likely leave an "etch," a chemical reaction that may leave a dull area or mark. Properly sealing the grout will give you time to wipe up a spill to avoid staining, but it cannot prevent etching. In addition, ordinary household cleaners with colored dyes or those containing bleach, ammonia or abrasives are not recommended for ceramic, porcelain tile & grout. They may damage the surface and likely degrade the sealer that is applied to the grout, which provides stain protection.

Food Spills
Scoop up food with a plastic spoon. Blot with a dry white cloth. Spray the area with a neutral cleaner and wipe off excess with a clean cloth.

Liquid Spills
Blot up the excess with a clean, dry cloth. Then clean the area with a ph-balanced cleaner and wipe off excess with a clean cloth.

Mud
Let the mud stain dry completely. Remove dried mud with a soft plastic nylon brush. Spray affected area with a neutral cleaner and wipe off excess with a clean cloth.
