Nothing makes a kitchen look as sleek as sparkling granite countertops, but it only takes a single stain to ruin that look. If you want to get rid of that stain, don’t reach for those harsh chemical cleaners under the sink; they might actually do more harm than good. It is especially important to stay away from cleaners that eat at the stone, like vinegar or anything made with lemon.
Here are a few ways to remove any stain from your granite countertops:
Materials
- A non-abrasive cloth or pad that won’t scratch the granite countertop (microfiber cloths work great).
- A pH-neutral soap (these soaps are usually labeled ‘mild,’ ‘gentle,’ or ‘great for hands’) or a granite cleaner.
- Plastic wrap
- Mixing bowl
- Masking tape
- Plastic putty knife (optional)
- A poultice (See below: different ingredients based on the kind of stain)
Poultice
For each kind of stain, there is a different poultice (a fancy word for a wet mixture). Each of these poultices is made of a solvent (a chemical to remove the stain) and an absorbent material (such as a paper towel, talcum powder, diatomaceous earth, or even flour).
If you know what caused the stain, it will make things easier to clean up. If you don’t know what caused the stain, try the first poultice on this list before moving on to anything harsher.
- For minor stains, use a mixture of baking soda and water. This will work on many kinds of stains without causing too much damage. You can also try a mixture of flour and soapy water. (Make sure to use a pH-neutral soap!)
- For organic stains (caused by coffee, soda, wine, fruit, etc.), soak paper towels in 12% hydrogen peroxide (don’t buy this from a drug store, get it from a beauty supply store). Be careful: hydrogen peroxide can cause dark areas to become lighter, so if you have dark marble, do not let the poultice sit for too long.
- For oil stains (caused by cooking oil, butter, etc.) mix one part water, flour, and pure acetone (make sure to purchase this through a beauty supply shop, do not use nail polish remover, as these can contain other ingredients).
- For inorganic stains (caused by ink, dyes, etc.) use hydrogen peroxide for light-colored stone or acetone for dark-colored stone.
- For metal stains (caused by rust, copper, etc.), use a mixture of diatomaceous earth and a commercially available rust remover. However, be warned that rust stains are very hard to remove, and you may need to call a professional to have these stains removed.
Removing The Stain
- Clean the area thoroughly with warm water and a pH-neutral cleaner.
- Let the area dry.
- Mix poultice ingredients in a bowl to form a thick paste (the consistency of peanut butter) and use it to cover the stained area with a thin layer. When using a liquid poultice, you can also just soak the liquid in paper towels.
- Cover the entire stain with the poultice.
- Place plastic wrap over the poultice and secure the edges of the plastic wrap to the counter with masking tape to ensure it stays put.
- Poke holes in the plastic wrap with a pin to allow it to slowly dry.
- Let the poultice sit for at least an hour. (For tougher stains, let the poultice sit overnight and up to 24 hours.)
- Remove the plastic and use a plastic putty knife or scraper to remove the poultice completely.
- If the stain is still visible after a few days, repeat the process.
- When you are done, make sure to re-seal the area that was cleaned to ensure that the area is protected from future stains.

Make sure to test this solution on a small, inconspicuous area of the countertop to ensure that there are no adverse effects. Some poultices do cause minor discoloration that goes away after a few days, so make sure to give it time to heal before freaking out. However, if the stain persists, you can always try a professionally-made poultice or call a professional granite cleaner.
