How to Remove Stains from Marble Countertops

Understanding Marble Stains

Marble stains fall into two categories that are often confused: stains (discoloration from substances absorbed into the stone) and etching (dull marks caused by acid reacting with the calcium in marble). This guide covers stains — for etching, see our separate guide.

Common marble stains include coffee, wine, oil, rust, and organic matter. Each requires a slightly different approach.

Golden Rules for Marble Stain Removal

• Never use vinegar, lemon juice, or bleach — these cause etching, not cleaning.
• Blot, don't rub — rubbing spreads the stain and pushes it deeper.
• Act fast — marble is porous and absorbs liquids quickly.

What You'll Need

• Baking soda — for poultice (organic and oil stains)
• Hydrogen peroxide (3%) — for organic stains on light marble
• Dawn Platinum Dish Soap — for oil-based stains
• Microfiber cleaning cloths
• Plastic wrap and tape
• Weiman Stone Cleaner — for finishing

Stain Removal by Type

Organic Stains (Coffee, Tea, Wine, Juice, Food)

1. Blot up as much as possible immediately.
2. Mix baking soda with hydrogen peroxide to form a thick paste.
3. Apply a ¼-inch layer over the stain.
4. Cover with plastic wrap, seal edges with tape.
5. Leave for 24–48 hours.
6. Remove, let dry, then gently scrape off and rinse with warm water.
7. Dry thoroughly and follow up with Weiman Stone Cleaner.

Oil-Based Stains (Cooking Oil, Butter, Lotion)

1. Apply a few drops of Dawn dish soap directly to the stain.
2. Let sit for 5 minutes.
3. Gently blot and wipe with a damp microfiber cloth.
4. For deeper stains, use a baking soda + dish soap poultice (same method as above, but use water instead of hydrogen peroxide).

Rust Stains

Rust stains on marble are tricky — standard rust removers like CLR are too acidic for marble. Use a marble-safe rust remover or consult a stone restoration professional for severe rust staining. Do not attempt DIY acid treatments.

Ink or Dye Stains

1. For light marble: dab a small amount of hydrogen peroxide on a cloth and gently blot the stain.
2. For dark marble: use acetone (nail polish remover) on a cotton ball — test in a hidden spot first.
3. Rinse and dry immediately.

The Poultice Method (For Deep-Set Stains)

A poultice is the most effective tool for stubborn marble stains. It works by drawing the staining substance back out of the porous stone as it dries.

1. Choose your base: hydrogen peroxide for organic stains, dish soap + water for oil stains.
2. Mix with baking soda to form a thick paste.
3. Apply generously over the stain (¼ inch thick).
4. Cover with plastic wrap, tape edges.
5. Wait 24–48 hours.
6. Remove plastic, let paste dry fully, then scrape and rinse.
7. Repeat up to 3 times for stubborn stains.

After Stain Removal: Reseal

Stain removal can deplete the sealant. Once the area is clean and dry, apply a fresh coat of stone sealer to protect against future staining.

Final Thoughts

Marble stains are treatable with patience and the right technique. The poultice method is your most powerful tool. Always finish with a stone-safe cleaner and check your sealant — a well-sealed marble surface is far more resistant to staining.
