Can You Remove Granite Counter Stains?

Granite counter stains might surprise you. If you expected your granite to be impervious to stains, you might be disappointed. The bad news: Granite is stain-resistant, not stain-proof. The good news: It’s much easier to extract stains from granite than other stones. How can you do so quickly, to erase the sinking feeling you get when you look at your marred countertop?

Granite Can Stain?

Yes, it’s possible for granite to stain. When it’s properly sealed and maintained, it’s difficult to stain, but it can still happen. Certain liquids can penetrate the surface if they’re left on the counter for long periods of time, especially if those liquids are highly acidic.

Lemon juice, red wine, tomato juice, grape juice, mustard and toothpaste are all common substances that stain. Even water can seep in and leave a cloudy, dark stain. It’s time to restore your beautiful granite to its previous, spotless condition.

For Water Stains and Moderately Stubborn Marks

For water stains, try scrubbing the surface with a mixture of water and mild dish detergent, then rinsing and drying the area. You could also use rubbing alcohol.

For all other stains that are fresh and haven’t had more than a day or two to seep into the stone, create a paste of baking soda and water. Use a soft-bristled scrub brush to work the stain out, then rinse the paste away. You may have to repeat this process to fully remove the substance from the stone.

For the Worst Stains

Highly resistant stains will require a more comprehensive approach. You can either purchase a poultice at a hardware store, or you can create your own extracting material using flour and hydrogen peroxide. Cover the stain with this thick mixture, then cover it with a plastic sheet and tape each edge down securely.

Wait about 24 hours, then gently scrape up the paste and rinse the countertop. Again, you may have to repeat this process to fully extract the stain.

Try to Clean Counters Right Away After Spills

Clean your countertops immediately after you spill anything, from water to wine. That’s the best way to protect against granite counter stains in the first place. Use a special granite cleaner — these products work by filling in the exposed pores of the stone and helping to prevent liquid absorption.

You should also test your counter’s seal by pouring water on it. Does the water bead up, or does it sink into the counter? When the seal’s effectiveness begins to fade, it’s time to call a professional to have your granite counters sealed again.
