Granite Maintenance 101: Sealing, Cleaning, and Common Mistakes
Granite countertops are loved for their natural beauty, durability, and long lifespan — but like all natural stone, they need proper care to stay looking their best. While they’re not high-maintenance, a little routine attention can go a long way in preserving the shine and protecting your investment.
Here’s everything you need to know about caring for your granite counters the right way.
Do Granite Countertops Need to Be Sealed?
Yes — most granite should be sealed to prevent staining. Because granite is a natural stone, it’s porous to varying degrees depending on the specific type.
A high-quality sealer helps:
Repel water, oil, and other liquids
Prevent staining and etching
Make daily cleaning easier
How often should you seal granite?
Most granite surfaces need sealing once a year, but some darker, denser granites may go longer. A quick water test (see below) will tell you if it’s time.
How to Tell if Your Granite Needs Sealing
Pour a small amount of water (about 1 tablespoon) on your counter.
Let it sit for 15–20 minutes.
If the water darkens the stone or is absorbed, it’s time to reseal.
If it beads up and stays on the surface, your seal is still good.
Daily Cleaning Tips
✅ Use a pH-neutral cleaner
Warm water and a mild dish soap work great for everyday cleaning. You can also use a granite-specific spray to keep the surface streak-free and protected.
✅ Use a soft cloth or sponge
Avoid abrasive pads or scrubbers that could scratch or dull the finish.
❌ Avoid acidic or harsh cleaners
Vinegar, lemon juice, ammonia, and bleach can eat away at the sealant and damage the stone.
Common Granite Maintenance Mistakes
Skipping the sealer: This leaves your counters vulnerable to stains and damage.
Using Windex or bleach: These can erode the sealant and dull the finish over time.
Cutting directly on the surface: Granite is hard, but it’s still better to use a cutting board — for both the stone and your knives.
Putting hot pans directly on the surface: Granite can handle heat, but sudden temperature changes could cause cracks over time. Always use trivets or hot pads.
Bonus Tip: Keep It Dry
While granite is stain-resistant when sealed, leaving standing water or oil on the surface for long periods can still cause discoloration — especially around sinks or cooktops. A quick wipe-down after use helps prevent issues.
