How to Clean Tile & Concrete Grout

Tile and cement grout gets dirtier and dirtier over time, even if it's tinted, and getting down on your hands and knees to scrub an entire floor's worth of grout with a toothbrush probably isn't appealing. Use oxygen bleach instead. Oxygen bleach is completely non-toxic and odor-free, and best of all, it soaks right into the grout to eliminate stains with very little scrubbing on your part.

Make grout look like new with oxygen bleach.
  1. Mix powdered oxygen bleach in a bucket with warm water. Use the manufacturer's recommended amount. Stir to dissolve.

  2. Pour the solution directly onto dry grout. Dry grout is probably going to soak it right up. Keep applying the bleach water so there is always water sitting on the grout. If you're dealing with walls, pour the solution into a spray bottle and spray generously directly onto the grout. It might soak right in---if this is the case, just add more so the grout is wet. Let the solution sit for 30 minutes.

  3. Scrub lightly after with a nylon-bristled brush, applying fresh solution as you scrub. If you scrub a small area and it's still not clean, apply more bleach water, let the solution sit for 10 more minutes and scrub again.

  4. Rinse the grout with clean water.
