Prep first
Before you start
- Look at where the mark is and how it showed up before you pick a method.
- Keep powder dry: dust it off before anything else.
- If a dull patch won't buff out, stop and call a stone restorer.
White marks on marble are usually deposits, residue, or acid etch marks that have dulled the stone itself. Etch marks are damage rather than dirt, and they need marble polishing powder or a professional restorer. Work out which one you have before you rub anything, since marble can't take acid and abrasives are only safe with care.
Check black marble in daylight so you can tell a deposit from an etch before you pick a method. For white stains on a marble counter, a pH neutral stone cleaner is the safer product, and it keeps the surface from dulling further. If a ring or etch still shows after a few gentle passes, stop and call a professional restorer rather than trying harder yourself.

7 steps
Step by step
Step 1 of 7
Work out which mark you have
A ring or spot that shows after water has dried is a water mark. A white powder that appears on new stone is efflorescence, and a dull patch that won't shine like the stone around it is an etch. Look at where the mark is and how it appeared before you choose a method.
Step 2 of 7
Dust off any white powder
If the mark is a powder, dust mop or vacuum it off so the stone is clear. Efflorescence can keep returning as the stone dries out, so repeat this several times.
Careful. Water on efflorescence only hides it for a while.
Step 3 of 7
Buff water rings with steel wool
For a water ring, buff the spot with dry 0000 steel wool using light strokes. Check the mark between passes so you stop as soon as it fades.
Careful. Steel wool is for water rings only; on an etch it adds scratches.
Step 4 of 7
Wet the etch and add powder
Wet the dull area with clear water so the powder can work. Then sprinkle marble polishing powder over the wet patch.
Step 5 of 7
Buff the powder into the stone
Rub the powder into the stone with a damp cloth, or use a buffing pad on a low-speed power drill for more pressure. Keep the area damp while you work.
Step 6 of 7
Keep buffing until it shines
Keep buffing until the etch mark disappears and the marble surface shines. Rinse the area with clear water to check the shine before you stop.
Step 7 of 7
Call in help for what's left
If the etch won't buff out, contact your stone dealer or a professional stone restorer for refinishing or re-polishing. If white powder keeps coming back after dusting, contact your installer to find and remove the cause of the moisture.

Best products for white marks on marble & natural stone
Pick a marble polishing powder made for stone rather than a general-purpose scouring product.
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
A water ring is gone when the spot no longer shows and the surface looks even under normal light. An etch is gone when the dull patch disappears and the marble shines again, which can take several rounds of buffing. If the dull patch is still there after steady buffing, stop and call a restorer.
What changes for yours
Adjust for your marble & natural stone
White on a marble counter
On a counter, most white marks are water rings, or etches from acidic food like lemon juice or vinegar that sat on the stone. Start by looking at the mark in good light, then choose dry steel wool for a ring or the polishing powder and buffing pad for an etch.
If the counter turns out to be granite rather than marble, the Granite guide covers that stone, which is a different material. Check the stone's name on the installer's paperwork or the counter's edge before you start.
Black marble
Black marble is still marble, so the rules above apply in full. Water rings and powder respond to the same dry buffing and dusting, while an etch needs the polishing powder and buffing pad.
Check the shine in good light after each pass, since a dark stone shows a dull patch clearly. Stop once the patch matches the stone around it, and call a restorer if it doesn't.
Efflorescence on new marble
Powder on new stone doesn't respond to buffing the way a ring does, so the approach is different. Keep dusting it off and let the stone finish drying, since the powder can keep returning for a while.
If it's still coming back once the stone is fully dry, the cause is moisture, and your installer is the person to call.
Water rings
A water ring is usually a mineral deposit left where water sat and dried, so it's best handled with small, patient passes. Work one spot at a time and keep the strokes light.
If the spot looks duller after a pass rather than clearer, stop, because the mark may be an etch and need the polishing powder instead.
Heavy or long-standing buildup
Old marks have had time to dry into the stone, so buffing alone often won't lift them. For a set-in mark, a poultice is the stronger option: spread it over the stain, cover it with plastic, and leave it 24 to 48 hours.
Repeat the poultice as needed, since difficult stains can take up to five applications. Don't mix acid chemicals into the poultice, because the reaction cancels it out. A poultice may dull polished stone, so check the shine after each round.
Some stains never come out completely, even after several rounds, so judge each one by what's lifting. If the mark is still there after repeated poultices, a professional stone restorer is the next step, and most stains can be pulled out during professional restoration.

Do home remedies work on white marks on marble & natural stone?
Many home remedies for white marks are meant for fabric, wood or metal. On marble, the steps above are the ones to use, and the rest either don't address these marks or are unsafe on stone. Black marble is still marble, so the same choices apply.

What makes it worse
Mistakes to avoid
Don't use vinegar or lemon on marble
Vinegar, lemon and other acidic cleaners etch or dull marble, limestone and travertine. On a stone that's already marked, that can turn a simple mark into a dull etch that's harder to fix.
Don't scrub with scouring powder
Scouring powders and creams can scratch marble, and scratches make the stone look dull. Use marble polishing powder with a damp cloth or buffing pad instead.
Don't use a descaler on marble
Store-bought limescale descalers aren't for marble, and no descaler should stay on any surface longer than 2 minutes. Never mix chlorine bleach with acid cleaners or ammonia.
Don't wipe a fresh spill
Wiping a fresh spill spreads it across the stone. Blot it up with a soft cloth first, then judge what's left.
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 remain after repeated poultices. Worn or damaged stone is best handled by a professional stone restoration company.
Questions
What causes white marks on marble?
Most are mineral deposits left when water dries, or residue from something else sitting on the stone. Those usually come off with the steps above, since they sit on the surface.
Why does white powder keep coming back on new marble?
That's efflorescence, which comes up as a new installation dries out. It often takes repeated dusting to clear, and it can return for a while. If it keeps coming back, the moisture source needs fixing, and your installer is the right person to call.
Will white marks come out of black marble?
Often, yes. Black marble is still marble, so the same steps apply: water rings and powder respond to light buffing, and an etch needs marble polishing powder. A deep etch may not vanish completely, and then a stone restorer can judge how much is recoverable.
Can I buff out an etch mark myself?
Yes, if the etch is shallow, the buffing steps above can often bring the shine back. If the dull patch won't go, a stone dealer or professional restorer can re-polish it.
Can a white mark on marble be permanent?
Yes, some can. Some white marks are damage rather than deposits, and an etch that won't polish out may stay visible. A stone restorer can tell you how much improvement is possible.
Can a poultice pull out set-in white marks?
It can lift set-in marks over repeated rounds, but it may not work every time. If it doesn't work, most stains can still be pulled out during professional restoration.
