Granite is one of the toughest countertop materials you can choose, but the wrong cleaner can slowly dull its shine and wear down the sealer that protects it. The good news is that keeping granite clean is simple once you know what to use.
The Best Everyday Granite Cleaner
For daily cleaning, you only need three things:
- Warm water
- A few drops of mild, pH-neutral dish soap
- A soft microfiber cloth
Wipe the counter with the soapy water, rinse with a clean damp cloth, and then dry with a second microfiber cloth. Drying is the step most people skip, and it’s the one that keeps water spots and streaks from building up.
If you prefer a spray, choose a cleaner labeled specifically for natural stone or granite. These are formulated to clean without breaking down your sealer.
How to Disinfect Granite Safely
Need more than soap and water, like after handling raw meat? Mix equal parts isopropyl (rubbing) alcohol and water in a spray bottle. Spray, let it sit for a few minutes, then wipe and dry. It disinfects without damaging the stone.
What NOT to Use on Granite
Many common household cleaners are too harsh for natural stone. Over time, they can etch the surface, dull the polish, and strip away the sealer. Avoid:
- Vinegar, lemon juice, or citrus cleaners. Acids are one of the biggest threats to a stone’s finish.
- Bleach and ammonia. These can dull the surface and weaken the sealer with repeated use.
- Glass cleaners. Most contain ammonia.
- Many disinfecting wipes. Some contain acids or harsh chemicals. Check the label before using them on stone.
- Abrasive powders, scouring pads, or steel wool. These can scratch the polish.
- Heavy-duty degreasers and bathroom cleaners. These are made for tile and porcelain, not natural stone.
A good rule of thumb: if the label doesn’t say it’s safe for natural stone, don’t use it on your granite.
Dealing With Hard Water Spots
Hard water is a fact of life in much of Utah, and it tends to leave mineral spots around faucets and sinks. It’s tempting to reach for a lime and scale remover, but most of those products are acidic and can damage granite.
Instead:
- Wipe the area with warm soapy water.
- Gently work the spot with a plastic scraper or a soft brush.
- Use a stone-safe cleaner for stubborn buildup.
- Dry the area after each use of the sink to keep spots from forming.
Drying around the faucet daily is the easiest way to prevent hard water buildup in the first place.
How to Remove Common Stains
Sealed granite resists most stains, but spills that sit for a long time can still leave a mark. A simple poultice can pull many stains out of the stone.
- Oil-based stains (cooking oil, grease): Mix baking soda with water into a paste about the thickness of peanut butter. Spread it over the stain, cover with plastic wrap, tape the edges, and let it sit for 24 hours. Remove, rinse, and dry.
- Organic stains (coffee, tea, wine): On light-colored granite, a paste of baking soda and hydrogen peroxide often works. Test in a hidden spot first, since peroxide can lighten darker stones.
For stains that won’t budge, reach out to a professional before trying anything stronger.
Is Your Granite Due for a Reseal?
Cleaning and sealing go hand in hand. If your granite starts absorbing spills faster, it may be time to reseal. Try this quick test:
- Place a few drops of water on the counter.
- Wait 10 to 15 minutes.
- If the stone darkens under the water, it’s time to reseal.

A Simple Granite Care Routine
- Daily: Wipe with warm water and mild soap, then dry.
- Weekly: Use a stone-safe cleaner for a deeper clean.
- As needed: Treat stains with a poultice and dry around the sink to prevent hard water spots.
- Periodically: Do the water test and reseal when needed.
