Even on well-sealed natural stone, the occasional stain happens — a forgotten coffee ring, an oil splash, a spill that sat overnight. The good news is that most stains can be drawn out of granite, quartzite, and marble with patience and the right method. Here is how to remove stains from natural stone countertops.
First, identify the stain
The right fix depends on the type of stain. Organic stains (coffee, tea, wine, food) often leave a brownish mark. Oil-based stains (grease, cooking oil, cosmetics) darken the stone. Knowing which you have helps you choose the cleaning agent for your poultice. When in doubt, a general approach works for most everyday stains on sealed stone.
The poultice method
For stains that have soaked into natural stone, a poultice is the go-to solution. A poultice is a paste that draws the stain up and out of the stone as it dries. To make one, mix a fine absorbent material — baking soda works well for many stains — with a little water (or, for oil-based stains, a touch of hydrogen peroxide for light stone or acetone) into a thick paste.
How to apply a poultice
Spread the paste over the stain about a quarter-inch thick, extending slightly past the edges. Cover it with plastic wrap and tape down the edges, then let it sit for 24 to 48 hours so it can dry and pull the stain out. Remove the plastic, let the paste dry fully, then gently scrape it away and rinse with water. Stubborn stains may need a second application. Patience is the key — the slow draw is what works.
For everyday surface marks
Not every mark is a deep stain. Surface residue often comes up with warm water, mild dish soap, and a soft cloth or a non-abrasive sponge. For hard-water spots, a damp cloth and gentle pressure usually do it. Always avoid abrasive pads, bleach, vinegar, and ammonia, which can damage the sealer and dull the finish. See our care guide.
A special note on marble etching
If the mark on marble is dull and slightly rough rather than discolored, it is an etch, not a stain, and a poultice will not fix it — etching is surface damage from acid. Light etching can sometimes be buffed with a marble polishing product. Learn more in marble countertop care.
Prevention is easier than removal
The best stain strategy is prevention: keep your stone sealed, wipe spills promptly, use cutting boards and trivets, and clean with gentle products. A well-maintained seal gives you time to catch spills before they ever become stains. See how to seal granite.
Frequently asked questions
How do you get a stain out of granite?
Apply a poultice paste over the stain, cover it, and let it draw the stain out over 24 to 48 hours. Repeat if needed.
Will a poultice fix marble etching?
No. Etching is surface damage from acid, not a stain. It needs a marble polishing product, not a poultice.
How do I prevent stains?
Keep stone sealed, wipe spills promptly, and use cutting boards and trivets.
