How do I maintain tile grout in my shower?

Proper grout maintenance is essential for preventing water damage and keeping your shower looking fresh - with Ottawa's hard water, regular cleaning every 1-2 weeks and annual sealing will extend your grout's lifespan significantly.

The key to grout maintenance is consistency and using the right products. Start with weekly cleaning using a pH-neutral cleaner specifically designed for tile and grout - avoid harsh chemicals like bleach or vinegar that can break down grout over time. For Ottawa homeowners, the mineral-heavy water means soap scum and calcium buildup happen faster, so staying on top of regular cleaning prevents these deposits from becoming embedded in the grout lines.

Deep cleaning should happen monthly using a grout brush (an old toothbrush works well) and a paste made from baking soda and water. Work the paste into the grout lines, let it sit for 10-15 minutes, then scrub gently and rinse thoroughly. For stubborn stains or mildew, use an oxygen bleach product rather than chlorine bleach, which can weaken grout bonds over time.

Sealing is critical in Ottawa's climate where temperature fluctuations cause expansion and contraction. Grout should be sealed annually, or bi-annually in heavily used showers. Test if your grout needs sealing by dropping a small amount of water on it - if the water absorbs within 5-10 minutes, it's time to reseal. Use a penetrating sealer specifically designed for your grout type (sanded vs. unsanded).

Prevention strategies include running your bathroom exhaust fan during and for 30 minutes after showers, squeegeeing walls after use, and addressing any caulk failures immediately. In older Ottawa homes with poor ventilation, consider upgrading to a more powerful exhaust fan to prevent moisture buildup that leads to mold and grout deterioration.

Watch for signs that maintenance isn't enough: cracking grout, persistent discoloration despite cleaning, or water stains appearing on walls or ceilings below the shower. These indicate the grout has failed and needs professional replacement. Ignoring failed grout in Ottawa's freeze-thaw climate can lead to significant water damage behind walls.
