How to Clean Marble Grout

Both marble and grout are easy surfaces to clean, when you apply the proper cleaning routine. It is important to find ingredients that will clean effectively yet be mild enough to cause no damage to either surface.

Retail products are available that will clean these surfaces, but they can be high priced, and may contain harmful chemical ingredients we wish to avoid. A homemade solution can be the perfect alternative.

Things You Will Need

+
  • Bucket
  • Water
  • Dish detergent
  • Baking soda
  • Mop or sponge
  • Old toothbrush

Warning

Remember to twist excess water out of your sponge or mop, as using too much water can penetrate the surface of the grout or marble, which can lead to mold and mildew growth.

  • Fill a bucket halfway with warm water, using about a gallon of water. Make sure the water is warm, as this will help the cleaning ingredients dissolve more easily, plus tend to loosen any residue on the grout.

  • Stir in four spoonfuls of liquid dish detergent, or about four squirts from the bottle. The key is to use a mild detergent that will lift residue and buildup without harming the marble or grout. A mild laundry detergent can be substituted for the dish detergent.

  • Add one cup of baking soda to the bucket. This mild cleaning agent will also deodorize the area, making it perfect for pet households and bathroom areas.

  • Place the mop or sponge in the bucket and swish to absorb the cleaning solution; then pull the mop out and twist to remove excess water from the mop.

  • Mop or sponge over the floors as you normally would, applying extra pressure to areas of grout that need extra attention. Repeat until satisfied with the result, and let the floor air dry.

  • For stubborn buildup that is not easily removed, follow up with a dusting of baking soda. While the floor is still damp, cover the grouted area with a heavy dusting of baking soda, and let it sit for a few minutes.

  • Use an old toothbrush or similar tool to scrub the baking soda into the grout, scrubbing away any residue that is stuck to the grout. When satisfied with the result, mop or sponge over the area once more to remove loose debris and baking soda.
