Maintaining grout in showers is critical for preventing moisture ingress behind the tile. Clean grout regularly with mild, pH-neutral cleaners to remove soap scum and mineral deposits. Use a soft-bristle brush to avoid abrading the grout surface. If the grout shows signs of staining or mold, professional-grade cleaning products specifically formulated for showers are recommended. Periodic sealing with a high-quality penetrating sealer is essential, as the sealer wears down over time due to soap and water exposure. Maintaining these seals keeps the grout non-porous and prevents mold, discoloration, and potential water damage beneath the shower tile.
