How to Clean Grout in 5 Easy Steps

If you have tile in your kitchen, bath or floor areas, you may have noticed stains or discoloration that makes the surface appear dingy. Grout lines get dirty from soaps, shoes and spills, so experts recommend a good cleaning about once a year for areas that see a lot of traffic. Follow these five easy steps to learn how to clean grout.

What you will need:

  • Two wet towels
  • Baking soda
  • Mixing bowl
  • Water
  • Cleaning brush
  • Sealant

Step 1: Gather Supplies
To get started, you’ll need the right brush and a solvent. You can purchase a grout cleaning brush from any big-box retailer, or use an old electric or manual toothbrush. You can make the cleaning solvent at home by mixing two parts baking soda and one part water in a bowl. (The result is a paste-like substance.)

Step 2: Clean the Area
Wipe down the area with water and a towel to remove any stains or debris on the tile, and have your paste ready.

Step 3: Scrub
Dip the brush into the cleaning paste to cover the bristles and then apply it to the grout area. Scrub the grout in a back-and-forth motion until you notice a change in the grout color. Continue until all of the grout has been cleaned.

Step 4: Dry the Area
Wipe the solvent off the surface with a clean, wet towel (or a large sponge) and let the area dry for 24 hours.

Step 5: Seal
Once the grout is clean, experts recommend sealing the seams, which is done with a grout-sealing product. The sealer protects the grout from wear and dirt, and prolongs the life of the tile area. You can purchase a grout sealer in a spray or one with a roller or brush applicator. Read the manufacturer’s instructions to apply the seal properly, and be sure to let it dry for the recommended time.
