Why You Need to Know “How to Clean Grout on Marble Floor”?
Grout is highly porous due to the components it is made of, and it will absorb dirt and spills. This will stain your lines over time, making them look discolored and dirty. Grout lines that are dirty can make your flooring look soiled, which is why they must be cleaned.
Grout in areas with high moisture can also become a thriving spot for mold (1). Unfortunately, avoiding these potential health risks isn’t simple. But one way you can help to keep mold at bay is by keeping the room well-ventilated.

How to Clean Grout on Marble Floor?
Grout in between marble floor tiles can become dusty and discolored over time, particularly if the marble floors are not cleaned regularly. So marble grout regular cleaning can help prevent discoloration, dirt accumulation, and the growth of harmful mold and fungi.
Here’s how to clean grout on marble floor using different methods:
A. Baking Soda
1. Tape the marble sides so that your cleaning agents don’t come into contact with it while cleaning the grout.
2. Wet a stiff-bristle toothbrush with warm water before using it. Brush the bristles with a small amount of baking soda.
2. With the toothbrush, scrub the grout between the marble tiles. To clean the grout, use a gentle back and forth motion with the toothbrush. Avoid getting the baking soda on the marble or brushing it with the toothbrush.
4. Rinse the grout with warm water and dry it immediately with a soft absorbent cloth once the dirt, discoloration, and any growth on the tiles have been removed.
5. Combine baking soda with warm water to form a paste that has the consistency of toothpaste.
6. Brush a small amount of the mixture into the grout using the bristles of the toothbrush, being careful not to get the mixture on the marble. Wipe away any excess mixture that gets on the marble. Allow the mixture to dry completely before removing it from the grout.
7. Clean the mixture with a cloth moistened with clean, warm water to remove it. With a clean, soft, and absorbent towel, wipe up any of the mixture that gets on the marble right away.
Rinse the grout as many times as necessary to completely remove the cleaning mixture.

B. Hydrogen Peroxide
Hydrogen peroxide is a great environmentally friendly cleaning agent. It’s a wonderful natural disinfectant that’s safer to use than chlorine bleach or ammonia-based products while also being less expensive.
Although it is generally safe to use on granite and light-colored marble, I would still recommend spot testing the first time just to be careful. Here’s how to clean grout between marble tiles:
1. To start, fill a spray bottle with a 50/50 mixture of hydrogen peroxide and water and spray it on the grout.
2. Let it sit for 15 minutes and then wipe clean.
3. If you have a particularly stained area, soak a small rolled-up towel in hydrogen peroxide overnight and apply it over the stain. You can use cling wrap to seal it in if it’s small enough. But NEVER mix hydrogen peroxide with bleach.
C. Oxygen Bleach
Powdered oxygen bleach, unlike chlorine bleach, can be used on any color of tile and grout. It is non-toxic and does not produce any foul odor (2). Here’s how to clean marble floors and grout using oxygen bleach:
1. Stir a bucket of warm water with a high-quality oxygen bleach powder to dissolve it.
2. Let the solution sit for at least 30 minutes after pouring it onto the floor and flooding the grout lines. As the solution absorbs into the grout, continue to add more.
3. Scrub lightly with a nylon brush and repeat as needed. This method is effective for those difficult-to-remove stains.
4. To keep your clean floor, add some oxygen bleach powder to your regular mopping routine. Scrub the tile surface with the mop but leave the mop water/oxygen bleach solution in the grout joints for 30 minutes before rinsing with clean water.
