UNDERSTANDING YOUR GRANITE COUNTERTOPS

Granite is a natural stone formed from cooled magma, making it incredibly durable and heat-resistant. However, this natural material is also porous, which means it can absorb liquids and stains if not properly sealed and maintained. The key to successful granite maintenance lies in understanding these characteristics and adapting your care routine accordingly.

Most granite countertops come pre-sealed from the manufacturer, but this protective barrier diminishes over time. Regular maintenance helps preserve the sealer’s effectiveness while preventing damage from daily use. The good news is that with proper care, granite countertops can last a lifetime while maintaining their original luster and beauty.

DAILY CLEANING AND MAINTENANCE

Proper daily cleaning forms the foundation of granite countertops maintenance and care. Start each day by wiping down your countertops with a soft, damp cloth to remove any overnight dust or residue. For routine cleaning, use warm water and a few drops of dish soap, avoiding harsh chemicals that can damage the stone or its sealer.

After cleaning, always dry your countertops thoroughly with a clean, soft cloth. This prevents water spots and eliminates any soap residue that might build up over time. Pay special attention to areas around the sink and stove, where moisture and cooking residues tend to accumulate.

Never use abrasive cleaners, bleach, or acidic substances like vinegar or lemon juice on granite surfaces. These products can etch the stone and compromise the protective sealer. Instead, invest in pH-neutral stone cleaners specifically designed for natural stone surfaces.

SEALING GRANITE COUNTERTOPS

Sealing is perhaps the most critical aspect of granite countertops maintenance and care. A proper sealer creates a protective barrier that prevents liquids from penetrating the stone’s porous surface. Most granite countertops need resealing every 12 to 18 months, though this timeline can vary based on usage and the type of sealer used.

To test if your countertops need resealing, perform the water test. Place a few drops of water on the surface and observe what happens. If the water beads up, your sealer is still effective. If the water soaks into the stone within 15 minutes, it’s time to reseal.

When sealing granite countertops, start by thoroughly cleaning the surface and allowing it to dry completely. Apply the sealer according to the manufacturer’s instructions, typically working in small sections. Allow the sealer to penetrate for the recommended time, then buff away any excess with a clean cloth. Wait 24 hours before using the countertops normally.

PREVENTING STAINS AND DAMAGE

Prevention is always better than repair when it comes to granite care. Use coasters under glasses and bottles to prevent water rings and potential staining from acidic beverages. Place trivets or hot pads under hot cookware, even though granite can withstand high temperatures, as extreme heat can potentially damage the sealer.

Clean up spills immediately, especially those from wine, coffee, oil, or citrus juices. Even with a good sealer, prolonged exposure to these substances can cause staining or etching. Use cutting boards when preparing food to prevent scratches from knives and other sharp utensils.

Avoid placing heavy objects on unsupported areas of your countertops, particularly near edges or corners where the stone might be more vulnerable to cracking or chipping.

ADDRESSING STAINS AND MINOR REPAIRS

Despite your best prevention efforts, stains may occasionally occur. For most stains on granite countertops, create a poultice using baking soda and water for oil-based stains, or baking soda and hydrogen peroxide for organic stains like coffee or wine.

Apply the poultice to the stained area, extending slightly beyond the stain’s borders. Cover with plastic wrap and tape the edges down. Allow the poultice to sit for 24 hours, then remove the plastic and let the mixture dry completely. The poultice will draw the stain out of the stone as it dries.

For minor chips or scratches, contact a professional stone restoration specialist. While small issues might seem manageable, improper repair attempts can worsen the damage and potentially require more extensive restoration work.

WEEKLY AND MONTHLY MAINTENANCE ROUTINES

Establish a weekly routine that includes a thorough cleaning of your entire countertop surface using stone-safe cleaning products. Pay attention to areas that receive heavy use, such as food preparation zones and areas around the sink.

Monthly maintenance should include a more detailed inspection of your countertops. Look for any signs of wear, new stains, or areas where the sealer might be failing. This is also an excellent time to deep clean any decorative edges or textured surfaces that might collect dust or grime.

Consider polishing your granite countertops monthly with a granite-specific polish to maintain their shine and add an extra layer of protection. Always follow the manufacturer’s instructions and use products specifically designed for natural stone.

FREQUENTLY ASKED QUESTIONS

How Often Should I Seal My Granite Countertops?

Most granite countertops should be sealed every 12 to 18 months, but this can vary based on usage and the type of sealer used. Perform the water test regularly to determine when resealing is necessary.

Can I Use Regular Household Cleaners on Granite?

No, avoid using regular household cleaners, especially those containing bleach, ammonia, or acids. These can damage the stone and its protective sealer. Use only pH-neutral cleaners designed for natural stone.

What Should I Do If My Granite Countertop Gets Scratched?

Minor scratches can often be buffed out by professionals, while deeper scratches may require professional restoration. Avoid attempting to repair scratches yourself, as improper techniques can worsen the damage.

Is It Normal for Granite to Show Water Spots?

Water spots can occur if you don’t dry the surface after cleaning or if hard water minerals build up. Regular drying and using a granite polish can help prevent and remove water spots.

Can Heat Damage Granite Countertops?

While granite is heat-resistant, extreme temperature changes or very hot items can potentially damage the sealer or, in rare cases, crack the stone. Always use trivets or hot pads as a precaution.
