How to Properly Clean Your Granite Countertops

Don’t Cause Unnecessary Damage

Granite countertops are one of the most durable and long-lasting surfaces you can install in your home. But like any natural stone, they require the right care to keep them looking beautiful. Using harsh chemicals or improper cleaning methods can dull the finish, weaken the sealant, or even leave permanent marks.

Here’s everything you need to know about safely cleaning granite countertops and keeping them looking like new for years to come.

1. Use a Gentle Daily Cleaner

Granite is naturally stain-resistant when sealed, but daily messes should still be cleaned with a gentle, non-abrasive solution. The best cleaning solution to use daily is warm water and mild dish soap.

Simply mix a few drops of dish soap with warm water and wipe the surface clean using a soft, microfiber cloth. Dry with a microfiber towel to avoid streaks. Avoid using abrasive sponges, harsh scrubbing pads, and scouring powders, as these can scratch the stone and dull the polished finish.

2. Skip Harsh Chemicals — They Damage Granite

Some popular household cleaners can actually break down your granite’s seal and cause long-term damage. Never use bleach, vinegar, ammonia, Windex or other glass cleaners, citrus-based cleaners, or highly acidic or alkalinic products on granite. They will erode the protective seal and make your granite more vulnerable to staining.

3. Disinfect Safely Without Damaging the Stone

If you want to disinfect your countertop, avoid harsh antibacterial sprays. A safe way to disinfect is to mix 50% water and 50% isopropyl alcohol in a spray bottle. Spray the stone lightly, and let it sit for 3–5 minutes. Then, wipe it clean. This method kills bacteria without harming the sealant.

4. Clean Spills Quickly — Especially Oils & Acids

Granite is durable, but certain spills should be cleaned right away to prevent staining. Wipe up the following immediately: wine, coffee, oil and grease, citrus juices, and tomato sauce. If left too long, these can seep into the stone — especially if the sealant is wearing down.

5. Use Cutting Boards, Not the Countertop

While granite is scratch-resistant, cutting directly on the stone can dull your knives, leave fine scratches over time, and introduce bacteria into the surface. Using a simple cutting board helps preserve your stone and kitchen tools.

6. Reseal Your Granite as Needed

Granite should be resealed periodically to maintain its stain resistance. Most countertops only need sealing once a year, though lighter-use kitchens may require it less often. To test if your granite needs resealing, pour a small amount of water on the counter. If it beads up, the seal is still strong. If it absorbs or darkens, it’s time to reseal.

HC Granite provides high-quality sealing during installation and guidance on how to maintain it.

7. Use a Granite-Safe Cleaner for Extra Shine

For a streak-free shine, consider using a cleaner specifically designed for granite. These products maintain the stone’s natural luster, are pH-balanced, and help protect the seal. Just make sure the label says granite-safe.
