How do I get my granite white again? Granite countertops are the crown jewel of many kitchens and bathrooms—especially when they’re pristine white. But over time, even the brightest white granite can lose its luster due to daily wear, spills, and buildup. If your once-glistening surface is now looking a little dull, yellowed, or stained, don’t worry. Here’s how to restore your granite and bring back that bright, clean white look.

1. Start With a Deep Clean

Before jumping into special treatments, give your granite a thorough clean:

• Use a pH-balanced stone cleaner or a mix of mild dish soap and warm water.

• Avoid acidic cleaners like vinegar or lemon, which can dull or etch the surface.

• Use a soft cloth or sponge (never anything abrasive).

• Rinse well and dry completely with a microfiber towel.

2. Check for Sealer Breakdown

Granite is porous and needs to be sealed regularly to stay stain-resistant.

• Pour a few drops of water on the surface. If it darkens or absorbs quickly, the sealer has worn off.

• Re-seal your granite using a penetrating stone sealer made for light or white granite.

3. Remove Stains With a Poultice

If your granite still looks yellowed or stained in spots:

• Mix baking soda and water (for oil-based stains) or hydrogen peroxide and baking soda (for water-based or organic stains) into a paste.

• Spread it over the stain, cover with plastic wrap, and let it sit for 24–48 hours.

• Gently scrape off the paste and rinse. Repeat if needed.

4. Whiten With Hydrogen Peroxide

For general brightening:

• Dampen a cloth with 3% hydrogen peroxide and gently rub the surface.

• This can lift light stains and whiten the stone without damage.

• Always test in a small corner first to be sure it doesn’t alter the finish.

5. Avoid Future Discoloration

• Wipe spills immediately, especially from acidic foods and colored liquids.

• Use cutting boards and coasters.

• Clean regularly with stone-safe products.

• Re-seal your granite every 6–12 months, depending on usage.

Bonus Tip: Professional Polishing

If all else fails and your granite still looks dull or yellowed, you may want to bring in a pro. Stone care specialists can refinish and polish granite surfaces to restore their original shine and brightness.
