Some tile and all grout is porous by nature. The cracks and crevices can capture and trap dirt, sand, grease, and other types of contaminants. Using hot water and a low dilution of mild detergent is recommended for upkeep of your flooring. To protect your floor, we do recommend having your tile and grout cleaned once a year professionally. Our tile & grout cleaning could also be referred to as restoration. In most cases, we are able to get your tile and grout back to the original color it was when first installed.
