Prep first
Before you start
- Blot the spill now.
- Test any cleaner on a hidden spot first.
- Look at the mark at a low angle to tell an etch from a stain.
- Keep hot pans on a trivet.
A yellow mark on marble can be a stain that has soaked into the stone or a change in the surface itself, and which one it is decides the fix. Marble doesn't tolerate acid at all, so the cleaning stays with water and a neutral stone product. If the mark has been set for a long time, expect a poultice repeated over several rounds, and know that deep rust or copper marks may stay permanently.
On a marble countertop or floor, keep the poultice on the mark and don't let it dry out between rounds. If the yellow on white marble is still there after a couple of rounds, stop and call a stone restorer.

6 steps
Step by step
Step 1 of 6
Blot the spill and test first
Blot the stain with a paper towel as soon as you notice it, pressing gently rather than rubbing. Note where the stain sits and how it appeared, because that decides which treatment comes next. Before you use any cleaner, test it on a hidden spot such as the back edge or a corner.
Step 2 of 6
Flush with water and mild soap
Flush the area with water and mild soap, then rinse several times to clear away the soap. Dry the stone with a soft cloth before you move on, so you can see what is left.
Step 3 of 6
Clean with a neutral stone cleaner
Clean the whole area with a neutral stone cleaner or stone soap, working across the stain with a soft cloth. Rinse and dry once more so the surface is clear for the next check.
Careful. Acids such as lemon and vinegar etch and dull marble, so keep them away from the stone entirely.
Step 4 of 6
Check for etching at a low angle
Hold a flashlight almost flat across the stone and look at the spot from the side. A dull patch that shows up in that light is an etch, not a stain, and it needs polishing rather than stain removal, so stop there for that area. If the spot still looks yellow or dark in ordinary light, go on to the poultice.
Tip. Do the check with the stone fully dry.
Step 5 of 624 to 48 hours
Apply a poultice for stubborn marks
Mix a white absorbent powder (kaolin, diatomaceous earth, whiting or talc) with your stone cleaner into a peanut-butter paste. Spread it 1/4 to 1/2 inch thick over the stain, cover it with plastic, and leave it for 24 to 48 hours.
Careful. Never use whiting or iron-type clays with acid chemicals in a poultice, because the reaction cancels the poultice.
Step 6 of 6
Remove and rinse the poultice
Scrape off the dried poultice with a plastic scraper, then rinse the spot with distilled water and dry it with a soft cloth. Check the stain in good light, and if it is still there, mix and apply a fresh poultice; difficult stains may take up to five applications.
Tip. Plan for several rounds rather than one.

Best products for yellow stains on marble & natural stone
Choose a neutral stone cleaner or stone soap labeled for marble, and skip any product that lists acid or bleach.
Granite Gold® Daily Cleaner
How we picked these: each product is made for this type of stain, its maker doesn't warn against using it on marble & natural stone, and its directions fit the steps above.
Finished the steps? How does it look?
Nice work. Let it dry completely and check it again in good light. Here is what done looks like:
How to tell it's really gone →A faint mark usually needs one more round, not a stronger product.
Heavy buildup usually takes more than one round.
Heavy or long-standing buildup →When to call a professional →How to tell it's working
Each round should lighten the yellow, and the spot should look more like the stone around it. When it matches once the stone is dry and shows no dull patch at a low angle, you can stop.
What changes for yours
Adjust for your marble & natural stone
Yellow on white marble
On white marble, a yellow mark shows up clearly against the stone, so the low-angle check matters even more. Stick to the stone cleaner and the poultice, since chlorine bleach isn't used on marble.
After each round, check the spot in the same low light, and stop once the mark matches the stone around it.
Yellow on marble countertops
Marble holds up well against heat, but a trivet under hot pots and pans keeps the stone safe. A countertop spill works the same way as any other: blot it first, then clean and check as the steps describe.
Wipe up drips from the poultice edges before they dry, and keep the plastic taped so the paste stays moist.
Yellow on Carrara marble
Carrara is a white marble, so every rule above applies, including no acids and no scouring. The same checks for etching and the same poultice steps work for it.
Test the stone cleaner on a hidden area first, then work in small sections so you can see the result of each round.
Marble floors
On a floor, the poultice has to stay put for the full time from the steps, so tape the plastic down at all four edges. Keep foot traffic off the area until the poultice is removed, and lay a towel nearby to catch any drips.
Once the poultice is rinsed, dry the spot fully before walking on it, then check for dull patches in low light.
Heavy or long-standing buildup
Old yellow that has sat in the stone for years is the hardest case, so set your expectations first. Repeat rounds of the poultice rather than reaching for a stronger product. Give each round the full time and rinse it off before you judge the result.
A stain that has dried into the stone can take up to five applications, and some may never come out completely. Poultices can dull polished stone, so check the surface after each round.
Deep rust is the hardest of all: it is extremely difficult to remove, and the stone may be permanently stained. Most stains like this can be pulled out during professional restoration, so that is the realistic next step once the spot stops responding.

Do home remedies work on yellow stains on marble & natural stone?
You will see many home remedies for yellow stains, but most are fabric tricks or acids that marble cannot take. Skip acids and fabric tricks; marble can't take them and the stone can be damaged.

What makes it worse
Mistakes to avoid
Don't wipe a fresh spill
Wiping drags the liquid across the stone and can carry it into a wider area. Blot it instead, working from the outside edge toward the center so the spill stays small.
Don't scrub with powders or pads
Scouring powders, creams and scrub pads can scratch the stone, and scratches make etches look worse. Use a soft cloth with the stone cleaner for the job.
Don't reach for bleach on rust
Chlorine bleach sets and intensifies rust or iron yellowing, so it makes the stain harder to remove. Skip it on any rust mark, since deep rust may stay even after careful work.
Don't use rust removers with hydrofluoric acid
Hydrofluoric acid attacks all stone, so a rust remover that contains it can ruin marble. Check the label of any rust product before you buy it for the stone.
When to call a professional
Call a professional stone restorer for etched areas you can't fix, deeper scratches and nicks, deep rust or copper stains, and stains that stay after repeated poultices. Periodic professional refinishing also keeps polished marble looking its best, and most stains can be pulled out during restoration.
Questions
Is yellow on marble permanent?
Often it can be lifted, but not always. Difficult stains may take up to five poultice rounds, and some never come out completely. Start with the blot and stone cleaner before deciding it is permanent.
How long should a poultice stay on marble?
Leave it 24 to 48 hours under plastic, then rinse it off with distilled water and check the spot. If the yellow is still there, repeat the poultice rather than switching to a stronger product.
Can a poultice dull my marble?
It can. A poultice may dull polished stone, so test it on a hidden spot first. A dull area that appears afterward is an etch and may need professional polishing.
What if the spot looks dull rather than yellow?
A dull spot is an etch, not a stain, so stain removal won't fix it. Check at a low angle, and if the dull patch stays, ask a stone restorer about polishing.
Can a professional remove the yellow stain?
Often yes. Most stains can be pulled out during professional restoration, and a restorer can handle etching and deeper marks you can't fix at home.
Is Carrara marble treated differently?
No. Carrara is a marble, so the same rules apply: no acids, no scouring, and a poultice for stubborn marks.
