Maintenance
For ongoing maintenance, sweep or vacuum the tiles. Clean the tiles regularly with a pH neutral cleaner and rinse with clean water. Use only neutral, non-abrasive and non-acidic cleaners. Avoid use of any harsh cleaning products that contain bleach or acidic chemicals. Acid-based cleaners and harsh chemicals may etch the surface of the tile, especially tiles with polished or honed finishes. It is important that the cleaner is a non-oil, non-soap and non-animal fat based product. These products act like a magnet, attracting dirt and dust. Always test cleaning solutions on a small inconspicuous area before proceeding to clean the entire surface area. For hard to remove residue, a single disc floor machine with a white pad may be used. Be sure to wet the surface first when using a floor machine
