How to Clean Marble Countertops: Protect Against Etching and Staining

Marble countertops are stunning — but they're also the most high-maintenance surface in the kitchen. Marble is calcium carbonate, which reacts instantly with acids. A drop of lemon juice, vinegar, or even wine left for a few seconds can etch the surface permanently, leaving a dull spot that can't be cleaned away. Here's how to care for marble correctly.

The Golden Rule: Avoid All Acids

Never use these on marble:

• Vinegar or vinegar-based cleaners
• Lemon juice or citrus cleaners
• Wine, coffee, or juice (wipe up immediately)
• Bleach or ammonia
• Abrasive scrubbers
• Any cleaner not labeled pH-neutral or stone-safe

What You'll Need

• Microfiber cloths (soft, non-abrasive)
• pH-neutral dish soap
• Warm water
• Baking soda (for stains only)
• Hydrogen peroxide 3% (for light-colored marble stains)

Daily Cleaning

1. Wipe the surface with a damp microfiber cloth and a tiny drop of pH-neutral dish soap.
2. Rinse with a clean damp cloth to remove all soap residue.
3. Dry immediately and thoroughly — standing water can cause mineral deposits and staining on marble.

Wipe up any spills — especially acidic ones — the moment they happen. Don't wait even a minute.

Removing Stains from Marble

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

1. Make a paste with baking soda and water.
2. Apply to the stain, cover with plastic wrap, and tape the edges.
3. Leave for 24-48 hours — the paste draws oil out of the porous stone.
4. Remove, wipe clean with a damp cloth, and dry.

Water-Based Stains (Coffee, Tea, Wine) on Light Marble

1. Make a paste with baking soda and 3% hydrogen peroxide.
2. Apply to the stain, cover with plastic wrap, and leave for 24 hours.
3. Wipe clean and rinse with water. Dry immediately.

Note: Only use hydrogen peroxide on light-colored marble — it can bleach dark marble.

What Are Etch Marks?

Etch marks are dull, lighter spots caused by acid reacting with the calcium in marble. They are not stains — they're physical damage to the surface. Light etching can sometimes be buffed out with a marble polishing powder. Deep etching requires professional re-polishing.

Sealing Marble

Marble should be sealed every 6-12 months to protect against staining. Use a penetrating stone sealer specifically designed for marble. Test by dropping water on the surface — if it absorbs rather than beads, reseal immediately.

Frequently Asked Questions

Can I use baking soda to clean marble?

Baking soda paste can be used carefully for stain removal — it's mildly alkaline and safe for marble. However, don't use it for daily cleaning as repeated use can dull the surface over time.

How do I remove coffee stains from marble?

Apply a paste of baking soda and hydrogen peroxide (for light marble only), cover with plastic wrap, and leave for 24 hours. For dark marble, use baking soda and water paste instead.

Can I use dish soap on marble?

Yes — a tiny amount of pH-neutral dish soap in warm water is safe for daily cleaning. Avoid using too much soap as it can leave a film that dulls the surface.

How do I get rid of water spots on marble?

Buff with a dry microfiber cloth. For stubborn water spots, dampen a cloth with water and a tiny drop of dish soap, wipe, then dry immediately. Prevent water spots by always drying marble after cleaning.
