Ceramic can be cleaned with just about anything. Ammonia and water mixture is the most commonly used method of cleaning your floor. To clean the grout, use a toothbrush with a mixture of water and comet.
Two weeks after the grout has cured, a grout sealer should be applied. This will help to resist staining and discoloration of the grout. We highly recommend that you apply sealer as the final step in your ceramic installation.
