Frequently Asked Questions About Natural Stone Cleaning and Care

Yes, high-quality natural stone cleaners are specifically formulated to be safe for delicate surfaces like marble. These cleaners are typically pH-neutral (around 7), meaning they are neither acidic nor alkaline, which is crucial because marble is composed of calcium carbonate and can be easily etched by acidic or harsh chemical products.

• Why pH matters: Acidic cleaners (like vinegar or lemon-based solutions) can cause permanent dull spots or etching on marble surfaces.
• Look for labels: Choose products labeled “safe for marble” or “pH-neutral” to ensure compatibility.
• Test first: Always test any cleaner on a small, inconspicuous area before full application.

Using a proper natural stone cleaner helps preserve the polish, prevent staining, and extend the lifespan of your marble countertops, floors, or vanity tops.

No, you should never use vinegar—or any acidic substance—to clean natural stone surfaces such as marble, limestone, travertine, or even some types of granite. Vinegar has a low pH (typically between 2–3), making it highly acidic, which can lead to significant damage over time.

• Etching: Acidic cleaners react with calcium carbonate in stones like marble, causing visible dull spots or etch marks that diminish shine.
• Surface degradation: Repeated exposure weakens the stone’s surface, making it more porous and prone to staining.
• Not just vinegar: Avoid other acidic household items like lemon juice, cola, or bathroom cleaners containing hydrochloric acid.

Even diluted vinegar can be harmful with repeated use. For safe cleaning, stick to pH-neutral stone cleaners or mild dish soap and water.

For granite countertops and surfaces, it's best to use either a ready-made, pH-balanced granite cleaner or a simple solution of warm water and a few drops of mild liquid dish soap for daily maintenance.

• Commercial granite cleaners: These are specially designed to clean without leaving residue or damaging the sealant. Look for brands that are non-abrasive and free from dyes or fragrances.
• Diy option: Mix a few drops of gentle dish soap (like Dawn) into a spray bottle of warm water. Wipe with a soft microfiber cloth—this method is effective and cost-efficient.
• Avoid: Harsh detergents, abrasive scrubbers (steel wool), or oil-based soaps that can degrade the sealer or leave greasy films.

Granite is more resistant than marble but still porous and requires protection. Regular cleaning with appropriate products helps maintain its beauty and durability.

Stone sealer should be applied regularly to protect natural stone surfaces from stains, moisture absorption, and everyday wear. Sealing creates an invisible barrier that repels liquids and prevents them from penetrating the pores of the stone.

• After installation: Always seal newly installed stone surfaces before use.
• Post-cleaning: Reapply sealer after deep cleaning or stripping old sealant buildup to ensure maximum protection.
• Routine maintenance: Depending on usage and stone type, reseal every 6–12 months. High-traffic areas like kitchen counters may need more frequent sealing.
• Test for absorption: Perform a water test—place a few drops on the surface. If it darkens or soaks in within 10 minutes, it’s time to reseal.

Sealing is especially important for porous stones like limestone, travertine, and sandstone, but even denser stones like granite benefit from periodic sealing to enhance longevity and stain resistance.
