How to Clean and Maintain Granite Countertops for Years of Beauty

Granite countertops are one of the most popular choices among homeowners for a reason—they’re elegant, durable, and add timeless beauty to kitchens and bathrooms. As a type of natural stone, granite offers a unique blend of strength and sophistication that few materials can match. However, like all natural surfaces, granite requires proper care to keep it looking as stunning as the day it was installed.

At Royal Marble and Granite, we believe that informed customers make the best choices. In this article, we’ll show you how to clean and maintain your granite countertops effectively so they remain a luxurious focal point in your home for years to come.

Why Granite Countertops Need Special Care

While granite countertops are incredibly durable and heat-resistant, they are also porous. This means they can absorb liquids if not properly sealed and cared for. Regular maintenance not only keeps your countertops looking their best, but it also helps extend their lifespan and prevent common issues like staining, dullness, and etching.

Proper maintenance isn’t complicated—it’s all about using the right products and techniques consistently.

Daily Cleaning Tips

Use a Mild Cleaner

To clean your granite countertops on a daily basis, simply use warm water and a few drops of mild dish soap. Avoid harsh or acidic cleaners, such as vinegar, lemon juice, or ammonia, which can strip the sealant and dull the surface of your natural stone.

What to Use:

• A soft cloth or sponge
  
  
• Warm water + mild soap
  
  
• A designated granite-safe cleaner
  
  

What to Avoid:

• Bleach
  
  
• Vinegar
  
  
• Abrasive scrubbing pads
  
  
• Ammonia-based sprays
  
  

At Royal Marble and Granite, we recommend pH-balanced cleaners that are specifically designed for natural stone.

Wipe Spills Immediately

Granite resists most stains, but if spills are left too long—especially from oil, wine, coffee, or acidic substances—they can seep into the surface. Always wipe up spills immediately with a soft cloth or paper towel to prevent absorption.

Weekly and Monthly Maintenance

Disinfect Safely

You can sanitize your granite countertops once or twice a week using a solution of 70% isopropyl alcohol and water (1:1 ratio). Spray lightly, let it sit for 3-5 minutes, then wipe clean with a microfiber cloth. This helps remove bacteria without damaging the stone or sealant.

Check for Dullness or Rough Spots

Run your hand across the surface regularly. If it feels rough or appears dull in some areas, it may be time to reseal the stone or do a deeper cleaning. A well-maintained granite surface should always feel smooth and glossy.

Sealing Granite Countertops

Why Sealing Is Important

Natural stone like granite is porous, which means it can absorb liquids and develop stains over time. A high-quality sealant prevents moisture and oils from penetrating the surface. Although many granite slabs come pre-sealed, reapplying sealant every 1–3 years helps maintain their protective barrier.

How to Test If Your Countertop Needs Sealing

Try the water drop test:

• Pour a few drops of water on the surface.
  
  
• Wait 10–15 minutes.
  
  
• If the water beads up, the seal is intact.
  
  
• If it darkens or absorbs, it’s time to reseal.
  
  

How to Reseal Granite

Sealing is a simple DIY task:

• Clean the surface thoroughly and let it dry.
  
  
• Apply a granite sealer evenly using a cloth.
  
  
• Let it sit for the recommended time (usually 15–30 minutes).
  
  
• Wipe off any excess.
  
  
• Let it cure for 24 hours before use.

Long-Term Care Tips

Use Cutting Boards and Trivets

Though granite is scratch- and heat-resistant, it’s best to use cutting boards and trivets:

• Prevent dulling of knives
  
  
• Avoid long-term heat damage
  
  
• Reduce surface wear
  
  

It’s all about preserving the polished finish of your granite countertops.

Avoid Sitting or Standing on the Countertop

Granite is strong—but it's not unbreakable. Sitting or standing on edges or overhangs can cause cracks or fractures over time, especially near weak points like sink cutouts.

Use Coasters and Avoid Heavy Chemicals

To prevent etching and rings from drinks or soap bottles:

• Use coasters for all beverages
  
  
• Avoid leaving toiletry products directly on stone vanities
  
  
• Avoid storing strong cleaners near your countertops
  
  

These small habits can help keep your natural stone looking beautiful for years.

Troubleshooting Common Issues

• Stains: Try a granite poultice for oil or wine stains.
  
  
• Cloudiness: Use a granite polish or call a professional for refinishing.
  
  
• Etching: Typically caused by acid exposure. May require refinishing.
