How To Remove Spots From Marble

There are a few things to keep in mind when removing stains from marble, as marble is a relatively soft, porous natural stone that is easily corroded (marked) by acids or stained by dark liquids. The wrong cleaning method can permanently damage the marble surface.

Tips for removing stains from marble

• Clean immediately: The shorter the stain is, the easier it is to remove.
• Avoid acids: Never use vinegar, lemon juice, ammonia, bleach (sodium hypochlorite), or any strong acid cleaners. They will corrode the marble surface and cause dull marks.
• Avoid abrasives: Do not use steel wool, scouring pads, or cleaning powders with abrasive particles, which will scratch the surface.
• Never pour marble stain remover chemical directly on the stone!
• Blot, not wipe: For liquid stains, blot first with a clean, absorbent cloth or paper towel, and do not rub hard (Rub) to prevent the stain from spreading or penetrating deeper.

How to Removing Spots from Marble

1. Use a mild, neutral detergent: pH-neutral detergents are preferred.
2. Blot the stain: If it is liquid, blot immediately with a clean paper towel or cloth to remove as much excess liquid as possible.
3. Rinse with warm water: Gently blot the stained area with a clean, damp cloth and warm water. Water alone is usually a safe and effective first step.
4. Dissolve a small amount of a neutral detergent designed for stone (or a mild dishwashing liquid) in warm water.
5. Dip a clean white cloth or sponge into the solution (wring out until dry) and gently blot the stained area.
6. Rinse thoroughly: Immediately wipe the area thoroughly with another clean, damp cloth and clean water to remove any detergent residue. Detergent residue can attract dirt and even damage the stone.
7. Dry thoroughly: Dry the surface thoroughly with a soft, dry, lint-free microfiber cloth. Residual moisture can leave water spots or cause mineral deposits.

How to Remove Oily Stains from Marble

Oily Stains (Grease, Butter, Makeup, Oily Food):

1. Method 1 (Preferred): Sprinkle a generous amount of baking soda or corn starch on the stain to create a layer of powder that covers the stain. Let sit for a few hours or even overnight to allow the powder to absorb the grease. Then gently brush off the powder with a soft brush, then wash with a solution of warm water and a neutral detergent, and finally rinse and dry thoroughly.
2. Method 2: Use a degreasing paste or paste cleaner designed for stone (usually containing ingredients such as kaolin). Follow the product instructions (usually apply it, cover it with plastic wrap and let it sit for a while), then remove the paste, wipe it with a damp cloth, and finally rinse and dry thoroughly.

How to Remove Beverage Stains from Marble

Organic Stains (Coffee, Tea, Red Wine, Juice, Food Coloring, Urine, etc.):

1. Method 1 (Preferred): Use 3% medical hydrogen peroxide. Pour the hydrogen peroxide on the stain, or soak a cotton swab/clean white cloth with hydrogen peroxide and cover the stain. Cover the cotton wool/cloth with plastic wrap to prevent evaporation too quickly. Let sit for at least 1 hour and up to 24 hours (check and replace the hydrogen peroxide during this time). Remove coverings, wipe with a damp cloth, then wash with a neutral detergent, and finally rinse and dry thoroughly. Hydrogen peroxide may have a slight bleaching effect on some dark marbles, so be sure to test first!
2. Method 2: Use an organic stain remover designed for stone. Follow the product instructions carefully.

After removing the spots, sealing is key! A good marble sealer penetrates the pores of the stone, forming a protective layer that greatly delays stain penetration. Newly installed marble must be sealed, and it is recommended to reseal every 1-2 years (depending on the frequency of use). Use a penetrating sealer (such as fluoropolymers or silanes) rather than a sealer that forms a film on the surface.
