What Does It Mean for Granite to Be Sealed?
Sealed granite has a protective barrier that helps keep out moisture, oils, and bacteria.
Before applying any cleaner to your granite countertops, it’s important to make sure they’ve been sealed. Granite is a hard material but it’s still porous. This means if sealant hasn’t been applied, any liquids or oils can be absorbed. To check whether your granite is sealed, place a few drops of water on the surface. If it beads up, your seal is secure. If the water soaks into the granite, it’s time to reseal.
Most granite countertops should be resealed every one to three years depending on the type of sealant used and how much daily wear the surface receives. If you are not sure whether your countertops need resealing, Legacy Countertops can help you assess the condition of your seal during a showroom consultation or service visit.
What Is the Best Way to Clean Granite Countertops Every Day?
The best daily method is warm water, mild soap, and a soft microfiber cloth.
Since you use your kitchen countertops every day for a variety of tasks, you’ll want a simple method of cleaning. For daily clean-up, use warm soapy water applied with a soft cloth. A microfiber cloth works great! You can’t get any easier than soap and water to clean food spills and debris.
How to Clean Granite Countertops Step by Step
1. Clear Away Crumbs and Spills. Use a dry cloth or paper towel to sweep away loose debris before applying any liquid.
2. Wipe with Warm Water and Mild Soap. Apply a small amount of mild dish soap to a damp microfiber cloth. Wipe the entire surface in smooth, even strokes.
3. Rinse the Cloth and Wipe Again. Remove soap residue by wiping with a clean, damp cloth. Soap buildup can leave a film over time if not rinsed.
4. Dry the Surface with a Clean Towel. Drying prevents water spots and keeps the granite looking polished. Use a soft, lint-free towel for the best finish.
5. Spot-Treat Any Stubborn Areas. For stuck-on food or dried spills, let a warm soapy cloth sit on the area for a few minutes before wiping. Avoid scraping with sharp tools.
This simple routine takes just a few minutes and helps keep your granite countertops looking like new.
What Cleaners Should You Avoid on Granite Countertops?
Avoid harsh, acidic, and abrasive cleaners because they can damage the sealant.
Never use a cloth or sponge with a rough texture. Stay away from steel wool and scouring pads. Avoid acidic cleaners, like vinegar, lemon, or lime. Don’t use bleach or ammonia. These are all harsh cleaners that will dissolve the sealant.
Even some “all-purpose” cleaners contain ingredients that are too strong for natural stone. Before using any new product on your granite, check the label to make sure it is specifically rated as safe for sealed stone surfaces. When in doubt, stick with mild dish soap and water.

How Can You Disinfect Granite Countertops Safely?
If your countertop is sealed, daily soap and water is usually enough for routine care.
Did you know that if your granite countertop is well-sealed, you don’t need to give bacteria much thought? Bacteria have a hard time breaking through the seal. That means hot water and mild soap are fine for daily cleaning. If you want something stronger, for example, after you’ve worked with raw chicken, you can make your own solution. Mix water and 91% isopropyl alcohol and spray the granite. You should use a 50/50 mixture.
Let the solution sit for three to five minutes and rinse with water. It can’t get any easier than that!
This is a practical way to disinfect kitchen countertops without harming natural stone.
How to Disinfect Granite Countertops Step by Step
1. Mix Your Solution. Combine equal parts water and 91% isopropyl alcohol in a clean spray bottle.
2. Spray the Surface. Apply the solution evenly across the countertop, focusing on areas that came into contact with raw food.
3. Let It Sit. Allow the solution to sit for three to five minutes so it can break down surface bacteria.
4. Rinse with Clean Water. Wipe the surface with a clean, damp cloth to remove the solution.
5. Dry Thoroughly. Use a dry towel to prevent water marks and restore the countertop’s shine.
Do You Need a Special Granite Cleaner?
You do not always need a special cleaner for granite countertops. You can find cleaning solutions made specifically for granite. There are even all-purpose cleaners that claim to be safe for granite. If you feel more comfortable using a cleaner created just for your granite countertops, feel free to purchase it. The beauty of granite is that you don’t need a fancy or expensive cleaner.
That said, a pH-balanced granite cleaner can be a good investment if you want extra convenience. These products are designed to clean without leaving streaks or residue, and they will not interfere with the sealant. Legacy Countertops carries a selection of stone care products and can recommend the right cleaner for your specific countertop material.
Why Is Granite Considered a Hygienic Countertop Material?
Granite can be one of the more hygienic countertop materials because a proper seal helps stop moisture and bacteria from getting into the stone. That makes routine cleaning easier and helps keep the surface sanitary for everyday kitchen use.
Compared to materials like tile or laminate, sealed granite has fewer seams and joints where bacteria can collect. The smooth, sealed surface is also easier to wipe down and less likely to harbor odors. This is one of the reasons granite remains a popular choice for Metro Atlanta homeowners who want both style and practicality in their kitchens.

Why Regular Granite Care Protects Your Investment
Granite countertops are a long-term investment in your kitchen. Homeowners who follow a simple care routine can keep their surfaces looking new for decades. Regular cleaning prevents buildup, resealing protects against stains, and avoiding harsh chemicals helps the finish stay consistent over time.
Well-maintained granite also contributes to your home’s resale value. Kitchens with clean, polished stone countertops create a strong first impression with potential buyers. Taking a few minutes each day for basic care can save you the cost of professional restoration down the road.

FAQs About Cleaning and Disinfecting Granite Countertops
A material-safe disinfecting method is the safest choice. For sealed granite, a 50/50 mix of water and isopropyl alcohol is a common option for disinfecting without using harsh acidic cleaners. Always check your seal before applying any new product. If you are unsure, contact Legacy Countertops for guidance.
Non-porous surfaces and properly sealed stone are often considered the most hygienic because they are easier to clean and less likely to absorb moisture. Sealed granite and quartz are among the top choices for homeowners who prioritize hygiene and easy maintenance.
Yes. Harsh disinfectants such as bleach, ammonia, and acidic cleaners can weaken sealants and damage stone surfaces over time. Stick with mild soap, water, or a granite-safe disinfectant to protect your investment.
Kitchen countertops should be cleaned daily and sanitized when needed, especially after contact with raw meat or messy food spills. A quick wipe with warm soapy water after each meal prep session is usually enough for sealed granite.
No. Vinegar is acidic and can wear down the protective seal on granite. Use a pH-neutral cleaner or plain dish soap instead. For a deeper clean, a 50/50 water and isopropyl alcohol spray is a safe alternative.
If water no longer beads on the surface and starts soaking in, the granite likely needs to be resealed. Most granite countertops benefit from resealing every one to three years. Legacy Countertops can help you determine the right schedule for your stone.
