Cleaning Granite Counters

Granite countertops are not only beautiful and luxurious, but they’re also highly durable, one reason they remain a popular choice in kitchens across the country. But if you’re wondering how to clean granite countertops properly, the key is using the right methods and products that protect their natural strength and polish without causing harm.

Though granite is one of the hardest natural stones, formed from hardened volcanic magma, it’s still porous. That means it can absorb liquids and oils, leaving behind stains or dull spots if not properly maintained. Luckily, keeping your granite looking spotless and stain-free is simple when you follow the proper routine.

Here’s what you need to know about how to clean granite countertops the safe and effective way.

Daily Cleaning: Simple Habits That Protect Granite

Creating a regular cleaning habit is the best way to preserve your granite’s shine and prevent damage.

The Do’s

• Wipe up spills immediately, especially acidic liquids like wine, citrus juice, or vinegar, which can etch or discolor the stone.
• Use a soft microfiber cloth for daily wipe-downs. It’s gentle, lint-free, and effective at picking up dust and residue.
• Use a pH-neutral granite cleaner or mix a small amount of dish soap with warm water. Always rinse and dry thoroughly.
• Dry with a clean towel to avoid water spots or mineral deposits from hard water.

The Don’ts

• Leaving standing water or wet items (like sponges or bottles) sitting directly on the countertop, this can lead to dark water marks or bacterial growth.
• Using generic all-purpose cleaners that may be too acidic or alkaline for natural stone.

Deep Cleaning and Stain Removal

Even with routine care, granite countertops can develop spots or stains. Here’s how to clean granite countertops when you need more than a basic wipe-down.

Food or Organic Stains

• Make a poultice paste: Combine 1–2 tablespoons of flour with a small amount of dish soap to form a thick paste.
• Apply the paste to the stained area, cover with plastic wrap, and let it sit overnight.
• Wipe off with warm water and a soft cloth in the morning.

Oil-Based Stains (milk, butter, cooking oil)

• Replace the dish soap in the poultice recipe with hydrogen peroxide.
• Follow the same overnight method, then rinse thoroughly.

Coffee, Tea, or Fruit Stains

• Mix 3% hydrogen peroxide with a few drops of ammonia.
• Gently dab the stain with a soft cloth anddo not scrub.

Always spot test any homemade cleaning solution in an inconspicuous area first to ensure it doesn’t dull the finish.

Resealing Granite Countertops

Knowing how to clean granite countertops also means knowing when they need to be resealed. Granite is typically sealed during installation, but over time, that protective layer wears down.

Testing Your Seal

• Drip a few drops of water on the countertop. If it beads up, the seal is intact.
• If the water spreads out and darkens the granite, it’s time to reseal.

Use a granite-safe sealer according to the manufacturer’s instructions, usually once a year, or more often in high-use kitchens. If you’re not comfortable doing this yourself, you can always call a professional.

What Not to Use on Granite

While granite is tough, some common cleaning products and tools can permanently damage it.

• Abrasive sponges, steel wool, or scouring pads – these can scratch and dull the polished surface.
• Acidic cleaners like vinegar, lemon juice, or bleach – they can etch or corrode the stone.
• Corrosive chemicals (oven cleaner, bathroom cleaners, ammonia, etc.).
• Metal scrapers or sharp tools – only use a wooden utensil or plastic scraper if needed.

How to Clean Granite Countertops Without Risk

To sum it up, how to clean granite countertops safely comes down to a few simple principles:

• Use pH-neutral or granite-specific cleaners.
• Clean spills right away.
• Never use abrasives or harsh chemicals.
• Reseal regularly to maintain the surface’s protection and shine.

Granite may look tough, and it is, but it still requires the right care. With just a few easy habits and the occasional deep clean, you can keep your granite countertops looking stunning and performing well for decades.
