How to Clean and Maintain Terrazzo

Terrazzo Maintenance Procedures:

Harsh cleaners and sealers can damage Terrazzo; thus, only materials that are neutral with a PH Factor between 7 and 10 should be used for cleaning Terrazzo floors. Avoid all-purpose cleaners or soaps containing water soluble, inorganic, or crystallizing salts, harmful alkali or acids for cleaning terrazzo. Sweeping compounds contain oil, which is not only a fire hazard, but will penetrate and could permanently discolor your terrazzo floor. Many of these compounds contain sand, which is hard to sweep, and can abrade your floor if not removed.

Terrazzo Cleaning Procedures:

Neutral cleaners are designed to react only in solution with clean water, mixed in accordance to the manufacturer instructions, and allowed to remain on the floor surface for several minutes. This provides the necessary time for the grime dissolving action to take place. Then rinse the dirt-laden solution from the surface by squeegee, vacuum, or mopping. Rinse with ample clean water. It is important to keep the floor wet during this entire cleaning process so the dirt does not reabsorb in the floor. The frequently asked question, “How often must we sweep or scrub this floor?” is answered by the amount of traffic that moves across the floor daily.
