Grout should be cleaned regularly to maintain its appearance and prevent the buildup of dirt, grime, and mold. Generally, it's recommended to clean grout every 1 to 3 months, depending on the level of foot traffic and exposure to moisture. High-traffic areas like kitchens and bathrooms may require more frequent cleaning, while less used areas may need attention less often. Routine cleaning helps preserve the grout's color and prevents stains from setting in. For areas exposed to high moisture, such as showers, a deeper cleaning every 6 months may be necessary to remove mold and mildew buildup. Regular maintenance not only keeps your grout looking fresh but also extends its lifespan.
