Once a year
Tackle scrubbing the grout in your shower (or any tiled surface) annually. You can easily brighten the grout with a simple, homemade cleaner.
1. Spray a 50-50 solution of water and chlorine bleach onto the grout (never use bleach on colored grout).
2. Let it sit for 20 minutes.
3. Then, using a grout brush dampened in clean water scrub to remove dirt and debris.
4. Blot with a dry cloth.
