How to Remove Stains From Marble (and Tell a Stain From an Etch)
Most marks on marble are one of three things: a stain that soaked in and looks darker, an etch where acid dulled the polish, or a water ring of minerals left on top. Each one needs a different fix, and the wrong one can make the mark worse.

Stain, Etch or Water Ring? Three Quick Checks
Tilt your head so light skims across the spot. What you see tells you which fix to use.
- Darker than the stone around it? That is a stain. Color soaked in below the surface.
- Dull or rough, and lighter or cloudy? That is an etch. Acid ate away the polish.
- White and chalky, and you can feel it with a fingernail? That is a mineral ring sitting on top.
Some marks are two things at once. A red wine spill can leave a stain and an etch together, and each needs its own treatment.
How to Get a Stain Out of Marble
A poultice pulls a stain back out of the stone. It does nothing for an etch, because an etch is lost polish, not trapped color.
Match the stain first, then test in a hidden spot.
- Oil, grease, lotion: use a poultice made for oil, with an alkaline or solvent-based liquid.
- Coffee, tea, wine, juice: use a hydrogen peroxide poultice, on light marble only. It can shift the color of dark or heavily veined stone.
- Rust: leave it to a pro. Most rust removers are acidic and etch marble.
- Clean and dry the area.
- Mix an absorbent powder, such as kaolin, with the liquid until it looks like peanut butter. Avoid chalk or whiting, which can react with some treatments.
- Spread it about 1/4 inch thick, slightly past the edges of the stain.
- Cover with plastic wrap, tape the edges, and poke a few small holes.
- Leave it 24–48 hours, until the poultice is dry.
- Scrape it off with a plastic tool, rinse, and wipe dry.
- Repeat up to a few times if the stain is still fading.
Judge the result once the stone has dried fully, since damp marble looks darker. If the mark gets worse or stops improving, stop and send us a photo.
How to Remove Water Rings and Hard-Water Marks
Water stains on marble come in two kinds. A dark ring that fades as the stone dries was only moisture. A white ring that stays is minerals or an etch.
Wipe the ring with a soft cloth and a pH-neutral stone cleaner, rinse, and dry. If a raised film remains, hold a plastic scraper nearly flat and use light pressure.
Keep razor blades, vinegar, lemon and CLR-type lime removers away from it. Acid etches marble.
Where you live changes what the ring probably is. City of Richmond water is moderately hard at 81 ppm, according to the 2025 Department of Public Utilities Consumer Confidence Report, so mineral rings around faucets are common. Chesterfield County water is naturally soft, so a white ring on a Chesterfield counter is more often an etch or cleaner residue.
Central Virginia humidity averages around 64%, so wet glasses and spills tend to sit longer before they dry.
What to Do About Marble Etching
Etching is damage to the polish, so wiping and poulticing will not fix it. A faint etch on polished marble can sometimes soften with a marble polishing compound worked in by hand.
Deeper or widespread etching needs honing and polishing by a professional. Our marble polishing page shows how that works, and marble restoration covers whole surfaces. For floors, see marble floor polishing.
Sealer does not stop etching. It only slows stains. Our marble countertop repair guide helps you sort out what a counter actually needs.
Prevent the Next Mark, Then Text Us a Photo
Use coasters under glasses, and wipe lemon, wine, tomato and cleaner spills right away. Clean with a pH-neutral stone cleaner. Reseal when water starts darkening the stone quickly.
Not sure which one you have? Text a photo of the mark and we'll tell you whether it is a stain, an etch or a water ring. Condition and size set the price, so the photo is the quickest way to find out.

Does sealing marble prevent etching?
No. Sealer slows stains from soaking in, but acid still dulls the polish on the surface. Wipe acidic spills quickly even on sealed marble.
Can baking soda remove stains from marble?
Baking soda mixed into a paste can lift some light surface marks, but it is not a full poultice. For stains that soaked in, use a poultice matched to the stain type and test a hidden spot first.
Can a stain in marble be permanent?
Sometimes. Old, deep or rust stains may only lighten, and a stain with an etch under it needs the polish restored too. Text a photo and we will tell you what is realistic.
