When you invest in beautiful natural stone countertops, flooring, or surfaces for your home, you’re making a choice that combines timeless elegance with lasting durability. At Imperial Marble & Granite, we’ve helped countless homeowners in the Delaware County area transform their kitchens, bathrooms, and outdoor spaces with premium granite, marble, and natural stone installations. But once your stunning new surfaces are installed, how do you keep them looking pristine for years to come?
Proper care and maintenance are essential to preserving the beauty and integrity of your natural stone. In this comprehensive guide, we’ll walk you through everything you need to know about sealants, cleaning techniques, and the critical dos and don’ts of natural stone care.
Understanding Your Natural Stone
Before diving into care instructions, it’s important to understand that different types of natural stone have unique characteristics and require slightly different maintenance approaches.
Granite is one of the most durable natural stones, resistant to heat, scratches, and stains when properly sealed. Its dense composition makes it ideal for high-traffic areas like kitchen countertops.
Marble is softer and more porous than granite, making it more susceptible to etching from acidic substances and staining. However, with proper care, marble surfaces maintain their luxurious appearance for generations.
Quartzite (not to be confused with engineered quartz) is a natural stone that’s even harder than granite, offering exceptional durability while showcasing beautiful natural patterns.
Limestone and Travertine are calcium-based stones that are more vulnerable to acids and require diligent sealing and maintenance.
The Critical Role of Sealants
Why Sealing Matters
Natural stone is porous to varying degrees, meaning it can absorb liquids, oils, and stains if left unprotected. Sealants work by filling these microscopic pores, creating a protective barrier that repels moisture and prevents staining. Think of it as an invisible shield that allows you to enjoy your stone’s natural beauty without constant worry about damage.
Types of Sealants
There are two main categories of stone sealants:
Penetrating Sealers (Impregnators): These sealers absorb into the stone and provide protection from within without altering the surface appearance. They’re ideal for most natural stone applications and are the type we typically recommend for countertops and floors.
Topical Sealers: These create a protective coating on the stone’s surface. While they offer robust protection, they can alter the stone’s appearance and may require more frequent reapplication, especially in high-traffic areas.
How Often Should You Seal?
The sealing frequency depends on the type of stone and its location in your home:
- Granite countertops: Every 1-2 years (some dense granites may need sealing less frequently)
- Marble surfaces: Every 6-12 months, especially in kitchens and bathrooms
- Bathroom vanities: Annually, due to exposure to water and personal care products
- Floors: Every 1-2 years depending on traffic
- Outdoor surfaces: Annually, as they’re exposed to more extreme conditions
The Water Test: When to Reseal
Not sure if your stone needs resealing? Perform this simple water test: place a few drops of water on your stone surface and let it sit for 10-15 minutes. If the water beads up, your seal is still effective. If the water is absorbed and darkens the stone, it’s time to reseal.
Professional vs. DIY Sealing
While homeowners can apply sealant themselves, professional sealing ensures even coverage, uses high-quality commercial-grade products, and comes with the expertise to address any existing issues before sealing. At Imperial Marble & Granite, we can assess your stone’s condition and recommend the best sealing schedule for your specific installation.
Daily Cleaning: The Foundation of Stone Care
The Right Way to Clean Natural Stone
Daily cleaning doesn’t have to be complicated, but it does need to be done correctly:
For routine cleaning:
- Wipe surfaces with a soft, damp microfiber cloth or sponge
- Use a pH-neutral stone cleaner specifically formulated for natural stone
- Dry the surface with a clean, soft cloth to prevent water spots
- For floors, use a dry dust mop or soft-bristle vacuum attachment to remove debris before mopping
For kitchen countertops: After food preparation, promptly wipe away any spills, especially acidic substances like lemon juice, tomato sauce, or wine. Use warm water and a mild dish soap or stone cleaner, then rinse thoroughly and dry.
For bathroom surfaces: Wipe down surfaces after each use to prevent soap scum and water spot buildup. Use a squeegee on shower walls to minimize water exposure.
Recommended Cleaning Products
Always choose pH-neutral cleaners specifically designed for natural stone. Avoid generic household cleaners, which often contain acids or alkaline ingredients that can damage stone and break down sealants.
Safe options include:
- Stone-specific cleaners from reputable brands
- A simple mixture of warm water and a few drops of mild dish soap (use sparingly)
- Commercial stone soap
Deep Cleaning for Stubborn Issues
Removing Stains
Different stains require different approaches:
Oil-based stains (grease, cooking oil, cosmetics): Create a poultice using baking soda and water to form a paste. Apply to the stain, cover with plastic wrap, and let sit for 24-48 hours. Remove and rinse thoroughly.
Organic stains (coffee, tea, wine, food): Use a poultice made with hydrogen peroxide (12%) and a white absorbent material like paper towels or powdered cleaners specifically for stone.
Water spots and rings: Buff gently with #0000 steel wool (for polished stone only), then reseal the area.
Soap scum (in bathrooms): Use a non-acidic soap scum remover specifically formulated for natural stone.
When to Call a Professional
Some situations warrant professional intervention:
- Deep or set-in stains that don’t respond to home treatment
- Etching or dull spots on marble or limestone
- Chips, cracks, or significant surface damage
- Complete restoration and repolishing needs
The Dos of Natural Stone Care
DO clean up spills immediately, especially acidic liquids like wine, coffee, citrus juices, and vinegar. The faster you act, the less likely staining or etching will occur.
DO use coasters under all glasses and bottles, particularly those containing alcohol or citrus juices. Even with sealed stone, prolonged exposure to these substances can cause damage.
DO use trivets or hot pads under hot cookware. While granite can handle heat, sudden temperature changes can cause thermal shock, and other stones may be more sensitive to heat.
DO use cutting boards for all food preparation. Even though granite is scratch-resistant, cutting directly on stone can dull your knives and potentially leave marks over time.
DO dust mop or vacuum floors regularly to remove grit and debris that can scratch the surface when walked upon.
DO use protective mats in high-traffic areas and under furniture to prevent scratching and wear.
DO establish a regular cleaning routine. Daily maintenance takes just minutes and prevents buildup that requires more intensive cleaning later.
DO check and maintain the caulk around sinks, backsplashes, and tubs to prevent water from seeping behind stone surfaces.
DO use appropriate pH-neutral cleaning products designed specifically for natural stone.
DO periodically test your sealant and reseal as needed to maintain optimal protection.
The Don’ts of Natural Stone Care
DON’T use acidic cleaners like vinegar, lemon juice, or ammonia-based products. These can etch and dull the surface of your stone, especially marble, limestone, and travertine.
DON’T use abrasive cleaners, scouring powders, or scrubbing pads that can scratch the stone’s surface. Even products labeled “safe for granite” may be too harsh.
DON’T use generic household cleaners. Products like Windex, bleach, or all-purpose cleaners often contain ingredients harmful to natural stone and can degrade sealants.
DON’T sit or stand on countertops. Natural stone is strong but can crack under concentrated weight, especially near edges or seams.
DON’T allow standing water to remain on surfaces, particularly marble. Water can penetrate the stone and cause staining or discoloration over time.
DON’T place toiletry bottles directly on bathroom counters. The bottoms can harbor moisture and residue that may stain or etch the surface. Use a tray or wipe bottles regularly.
DON’T use furniture polish or wax on natural stone. These products can create a buildup that attracts dirt and makes the surface appear dull.
DON’T mix cleaning products. Combining different cleaners can create harmful chemical reactions and may damage your stone.
DON’T neglect regular maintenance. Small issues become bigger problems when ignored, potentially requiring costly professional restoration.
DON’T drag heavy objects across stone surfaces. Always lift items to prevent scratching.
DON’T use your natural stone surfaces as a chopping board, even though granite is hard. Protect both your stone and your knives.
DON’T apply sealant to dirty stone. Always thoroughly clean and dry surfaces before sealing.
