How to Maintain and Clean Granite Countertops

Granite is highly durable and naturally resistant to bacterial growth, making it an ideal material for countertops in kitchens and bathrooms, as well as shower walls and backsplashes. Because granite is a porous surface, it is usually sealed upon installation. However, regular use and cleaning can gradually wear away the sealant, resulting in stains, damage, and a dull appearance. Fortunately, with the proper cleaning methods, granite is relatively simple to care for.

Fortunately, you don't need any specialized cleaners—everything you need to keep your granite countertops gleaming may already be in your home. Continue reading for step-by-step instructions and expert tips on how to clean granite countertops.

How Often Should You Clean Granite Countertops?

In the kitchen, granite countertops and backsplashes should be wiped down after each meal prep, or at least once a day to remove spills, splashes, and food remnants.

In the bathroom, use a towel or squeegee to dry off granite countertops or shower surfaces after every use to avoid water spots and soap scum buildup. For optimal care, bathroom countertops should be given a thorough cleaning once a week.

Things to Keep in Mind Before You Start

Before you start, clear off all appliances, dish racks, and any decorative items from your countertops, leaving them completely empty. Next, remove any crumbs or debris. For a deep clean, it's best to clean the entire surface of your granite countertops rather than just spot-cleaning specific areas.

Steps for Cleaning Granite Countertops

Although granite is generally resistant to most stains from food and liquids, avoid using harsh cleaners such as ammonia, abrasive scrubbing powders, undiluted bleach, or cleaning vinegar, as these can damage and dull the protective sealant.

Clear Dust and Spills from the Surface

Before starting your regular cleaning routine, use a damp microfiber cloth or a duster to pick up any dust and loose dirt. Otherwise, you'll just spread the soil around on the granite. Additionally, be sure to clean up any food or drink spills immediately with an absorbent, lint-free microfiber cloth.

Prepare the Cleaning Solution

Fill a spray bottle with four cups of water and one teaspoon of dish soap. A degreasing dishwashing liquid is ideal to get the countertops sparkling clean. Don't forget to label the spray bottle so you can easily identify the solution for future use.

Clean the Countertops

Lightly spray the granite countertops with the water and dishwashing liquid mixture. Use a clean microfiber cloth to wipe the surface and allow it to air dry naturally.

How to Maintain Granite Countertops for Long-Lasting Cleanliness

• Avoid exposing granite surfaces to sudden temperature fluctuations that could cause small cracks. Always use a trivet beneath appliances that apply prolonged heat or cold to the surface.
• Always use a cutting board when preparing food on kitchen counters to prevent scratches that can dull the stone.
• Immediately clean up spills and wipe down surfaces after meal preparation.
• Test the granite sealant by dropping a few drops of water onto a frequently used area. If the water beads up, the sealant is still effective. If the water spreads out, it's time to reseal.

How to Remove Stains from Granite Countertops

If your countertops feel sticky or greasy after cleaning, or have stains from red wine or tomato sauce, here's how to clean and remove them.

For grease stains: Combine one cup of cool water and one cup of isopropyl alcohol in a spray bottle for a disinfectant solution. Lightly spray the granite and wipe it clean with a microfiber cloth. Let it air dry.

For food stains: Combine baking soda with a few drops of hydrogen peroxide in a small bowl until you form a paste that's thick, similar to peanut butter. Spread this paste about a quarter-inch thick over the stain and cover it with plastic wrap. Tape the edges of the wrap to secure it in place. Let the paste sit for 24 hours, then remove the wrap and wipe off the paste. Repeat the process if necessary until the stain disappears.
