Granite countertops are a gorgeous complement to any bathroom or kitchen, giving your area style and toughness. However, despite their strength, they are not stain-proof. Spills, oils, and everyday use can cause unsightly marks and dullness over time. Stains can seep into the surface without proper granite countertops cleaning and maintenance, and the stone can lose its natural beauty.
In this guide, we’ll cover the best methods to remove tough stains from granite countertops and how to protect them from damage. Whether you’re dealing with food spills, water rings, or deep-set oil stains, these expert tips will help restore and maintain your granite countertops for years.
Understanding Granite Countertop Stains: Why Do They Happen?
Granite is a porous stone that can absorb liquids if it is not properly sealed. While a high-quality sealant helps prevent staining, it’s not foolproof. Common substances like coffee, wine, citrus juices, and oils can penetrate the surface if left unattended. Cleaning and maintaining granite countertops are essential to prevent long-term damage.
Common Types of Stains on Granite Countertops
- Oil-Based Stains: Cooking oils, butter, and greasy foods can leave dark spots on the surface.
- Water Stains & Hard Water Deposits: Mineral buildup from water can create cloudy spots on the stone.
- Organic Stains: Coffee, tea, and wine can leave brownish or reddish discolorations.
- Etching from Acidic Liquids: Lemon juice, vinegar, and soda can weaken the sealant, leading to dull patches.
Now that we know what causes stains let’s dive into the best techniques for cleaning and maintaining effective granite countertops.
How to Remove Stains from Granite Countertops
1. Baking Soda and Water for Oil Stains
For oil and grease stains, make a paste with water and baking soda. After applying it to the afflicted area, wrap it in plastic wrap. Use a moist cloth to gently wipe it away after letting it sit for a full day. This method helps lift deep-set stains without damaging the stone.
2. Hydrogen Peroxide for Organic Stains
If there are coffee, tea, or wine stains on your granite, combine hydrogen peroxide with a few drops of dish soap. Apply it to the stain, let it sit for a few minutes, and wipe clean with a damp cloth. Repeat as needed for deeper stains.
3. White Vinegar for Hard Water Stains (Use with Caution)
For water rings and mineral buildup, dilute white vinegar with equal water and wipe the area. However, since vinegar is acidic, use it sparingly and reseal the granite afterward to maintain protection.
4. Poultice Paste for Tough Stains
A poultice can help with deep stains. Create a thick paste by combining hydrogen peroxide and baking soda, then apply it to the stain and cover it with plastic wrap. Let it dry for 24-48 hours, then wipe it clean. Repeat if necessary.
5. Warm, Soapy Water for Everyday Cleaning
Regularly wiping your countertops with mild dish soap and warm water is one of the easiest ways to keep them stain-free. Steer clear of harsh chemicals since they have the potential to gradually erode the sealant.
How to Protect Granite Countertops from Damage
1. Use a High-Quality Sealer
Sealing your granite countertops is the best way to prevent stains and damage. Depending on usage, reseal your countertops every 6-12 months to maintain a strong protective barrier. NSR Pros offers professional sealing services that enhance the durability of granite surfaces
2. Wipe Spills Immediately
Even with a good sealant, spills should be cleaned immediately to prevent absorption. Blot spills instead of wiping to avoid spreading the stain.
3. Avoid Harsh Cleaners and Chemicals
Bleach, ammonia, and acidic cleaners (like lemon-based products) can erode the sealant and damage the stone. Stick to pH-neutral cleaners designed for granite countertops cleaning and maintenance.
4. Use Cutting Boards and Coasters
While granite is highly durable, cutting boards and coasters prevent unnecessary scratches and etching from acidic drinks or sharp objects
5. Don’t Place Hot Pans Directly on the Surface
Although granite can withstand heat, extreme temperature changes can weaken the sealant. Always use trivets or heat-resistant pads under hot cookware.
