Cleaning shower tiles regularly is essential to prevent soap scum, mold, and mildew buildup. Start by spraying a mixture of vinegar and water or a mild tile cleaner onto the tiles, letting it sit for a few minutes to break down grime. Use a scrub brush or sponge to scrub the tiles, paying extra attention to grout lines where dirt tends to accumulate. Rinse thoroughly with warm water and dry with a clean cloth to prevent water spots. Regular weekly maintenance keeps tiles looking fresh and extends their lifespan.
