Keeping New Tile Grout Clean

DIY Questions and Answer October 9, 2014 Sonia



Q: What’s the best way to keep new tile grout clean?

A: Cementitious grout is subject to staining because it is a porous material. Most professionals recommend applying a sealer after the grout has cured, typically in three days. The sealer should be reapplied periodically to maintain an enhanced level of stain resistance. Additionally, some newer grout formulations are stain-resistant right out of the pail against common household staining agents. Also, check the product packaging for indications of Microban anti-microbial protection that resists the growth of mold and mildew on dried grout.
