Avoid These Common Mistakes When Cleaning Natural Stone

Natural stone surfaces, such as marble, granite, limestone, and travertine, add elegance and sophistication to any space. However, improper cleaning techniques can damage, dull, and deteriorate these beautiful surfaces. In this article, we'll highlight some of the most common mistakes people make when cleaning natural stone and provide tips on avoiding them, ensuring your stone surfaces retain their beauty and longevity.


Using Acidic or Abrasive Cleaners

One of the most significant mistakes people make when cleaning natural stone is using acidic or abrasive cleaners. Substances like vinegar, lemon juice, or ammonia-based cleaners can etch and damage the surface of certain types of stone, especially marble and limestone. Similarly, abrasive cleaners or scrubbing pads can scratch and dull the surface, detracting from its natural beauty.


Tip: Opt for pH-neutral, non-abrasive cleaners specifically formulated for natural stone. These gentle cleansers effectively remove dirt and grime without harming the surface. Additionally, soft cloths or brushes are used to clean the stone to avoid scratching it.


Neglecting to Seal the Stone

Failure to seal natural stone surfaces leaves them vulnerable to stains, moisture penetration, and other forms of damage. Many people overlook the importance of sealing, assuming that the stone is naturally resistant to stains and spills. However, even the most durable stones benefit from regular sealing to maintain their protective barrier.


Tip: Seal your natural stone surfaces regularly using a high-quality stone sealer recommended by professionals. Follow the manufacturer's instructions for application and reapplication intervals to ensure maximum protection against stains and moisture.


Using Excessive Water

Excess water during cleaning can seep into natural stone pores, causing discoloration, staining, and even structural damage over time. Some homeowners mistakenly believe that soaking the stone with water will help loosen dirt and grime, which can lead to undesirable consequences.


Tip: Use minimal water when cleaning natural stone surfaces. Dampen a soft cloth or mop with water and a mild stone cleaner, then gently wipe the surface to remove dirt and stains. Immediately dry the surface with a clean cloth to prevent water from penetrating the stone.


Ignoring Regular Maintenance

Neglecting regular maintenance of natural stone surfaces can accumulate dirt, grime, and stains, detracting from their appearance and longevity. Many people wait until their stone surfaces are visibly dirty or damaged before taking action, exacerbating cleaning challenges and leading to more extensive restoration efforts.


Tip: Establish a regular cleaning and maintenance routine for natural stone surfaces. Sweep or dust the surfaces daily to remove debris and prevent scratches. Wipe up spills promptly to prevent staining, and clean the surfaces weekly or as needed using gentle cleaning solutions and techniques.


Using Improper Cleaning Tools

Using inappropriate cleaning tools, such as harsh brushes, scouring pads, or abrasive cleaning agents, can cause irreparable damage to natural stone surfaces. Rough materials can scratch, etch, or dull the surface, compromising its integrity and appearance.


Tip: Choose cleaning tools specifically designed for natural stone, such as soft-bristled brushes, microfiber cloths, or natural sponge pads. Avoid abrasive materials that can scratch or damage the surface, and always test new cleaning products or tools in an inconspicuous area before using them on the entire surface.


Conclusion

Cleaning natural stone surfaces requires care, attention to detail, and appropriate cleaning techniques and products. By avoiding common mistakes such as using acidic cleaners, neglecting to seal the stone, using excessive water, ignoring regular maintenance, and using improper cleaning tools, you can preserve the beauty and integrity of your stone surfaces for years to come. Follow the tips outlined in this article to ensure that your natural stone surfaces remain pristine, elegant, and inviting for generations to enjoy.

Bathroom Stone Care: Preventing Mold, Mildew, and Water Damage

By Kaylee Toole • June 9, 2025
Natural stone brings elegance and luxury to bathroom spaces, but it also comes with unique maintenance challenges. Bathrooms are high-moisture environments where water exposure, humidity, and poor ventilation can lead to mold, mildew, and water damage if stone surfaces are not adequately cared for. Whether you have marble, travertine, limestone, or granite in your bathroom, the key to preserving its beauty is routine care and moisture control. 1. Choose the Right Stone and Finish Before we dive into care tips, it's essential to understand that not all natural stones are created equal in terms of moisture resistance. Granite and quartzite are denser and more resistant to water damage. Softer stones, such as marble, limestone, and travertine, are more porous and absorb moisture more readily. Polished finishes offer more protection against water and staining than honed or tumbled finishes. If you're remodeling, choosing a less porous stone or a sealed polished finish can reduce maintenance needs. 2. Seal Your Stone Surfaces Regularly Natural stone is porous, meaning it can absorb water, soap residue, and body oils. This absorption can lead to staining, etching, or mold growth over time. A high-quality penetrating sealer provides a protective barrier that repels moisture and contaminants, offering enhanced protection against environmental damage. How often you should seal your bathroom stone depends on the type of stone and the amount of use the bathroom receives. Generally, sealing once or twice a year is recommended for high-moisture areas, such as showers and floors. How to Test Your Sealant: Sprinkle a few drops of water on the stone. If the water beads on the surface, the seal is still effective. If it soaks in and darkens the stone, it’s time to reseal. 3. Improve Ventilation and Airflow Poor ventilation is one of the most significant contributors to mold and mildew growth in bathrooms. Without proper airflow, moisture lingers in the air and on surfaces, creating the perfect environment for mold spores. Tips to improve ventilation: Use an exhaust fan during and after showers Leave the bathroom door open when not in use Wipe down shower walls and countertops after use Use a dehumidifier if the bathroom lacks adequate airflow 4. Clean Regularly with Stone-Safe Products Cleaning natural stone surfaces with the right products helps remove residue before it can penetrate the stone or encourage the growth of mold. Avoid using bleach, vinegar, or acidic bathroom cleaners, as they can damage the surface and degrade the sealer. Instead, use: A pH-neutral stone cleaner A soft microfiber cloth or non-abrasive sponge A squeegee for glass and polished stone surfaces in the shower Clean shower walls and floors at least once a week. Wipe down vanities and countertops daily. 5. Address Grout and Caulk Lines Grout and caulk lines are often overlooked but are among the most vulnerable parts of a bathroom. They can crack, separate, or absorb moisture over time, providing a breeding ground for mold and mildew. Even sealed stone is at risk if the grout is compromised. Inspect grout and caulk regularly. Reseal grout annually, and replace cracked or deteriorated caulk as soon as possible. Mold that forms in grout lines should be treated quickly with a stone-safe mold remover. 6. Avoid Leaving Standing Water Leaving water to sit on your stone surfaces can lead to water spots, discoloration, or eventual deterioration of the sealant. This is especially important in stone showers and on bathroom vanities. After using the shower or washing your hands, make it a habit to: Wipe down countertops and sinks Squeegee water from the shower walls and floors Dry off any wet areas to prevent water from soaking into the stone 7. Watch for Signs of Water Damage Early signs of water damage include: Darkened stone or water rings Efflorescence (white powdery residue) Dull or etched spots on polished surfaces Musty odors or visible mildew If you notice any of these signs, take action immediately. You may need to reseal, deep clean, or, in some cases, consult a professional for restoration. Conclusion Natural stone can be a stunning and durable choice for bathrooms, but it needs special attention in wet and humid environments. Regular sealing, proper cleaning, moisture control, and maintenance of grout and caulk are crucial in preventing mold, mildew, and water damage. With a few consistent habits and the proper care routine, your bathroom’s stone surfaces can maintain their beauty and strength for years to come. If your stone is showing signs of wear or damage, consider consulting a professional for a deep cleaning, polishing, and sealing treatment to restore its original condition.

How to Safely Disinfect Natural Stone Without Causing Damage

May 12, 2025
The COVID-19 era brought increased awareness around hygiene and disinfection in our homes and businesses. While keeping surfaces clean and germ-free is essential, it's equally important to ensure that your cleaning methods don’t damage the surfaces themselves, especially when it comes to natural stone like marble, granite, limestone, and travertine. Natural stone is beautiful and durable, but also porous and sensitive to certain chemicals. Using the wrong disinfectants can lead to etching , staining , and dulling of the stone’s finish. In this article, we’ll walk you through how to safely disinfect natural stone surfaces without compromising their integrity. Why Traditional Disinfectants Can Be Harmful to Stone Many common disinfectants contain acidic ingredients like vinegar , lemon juice , or bleach , which can: Etch the stone, leaving dull spots or cloudy patches. Break down sealants , reducing the stone’s resistance to moisture and staining. Discolor the surface, especially on light-colored stones like marble and limestone. Even alcohol-based products can cause long-term issues if used too frequently or left on the surface without wiping. Safe Disinfection Methods for Natural Stone 1. Use a pH-Neutral Stone Cleaner with Antibacterial Properties Some stone-safe cleaners are formulated to disinfect without causing harm. Look for labels that specify: pH-neutral Safe for natural stone Antibacterial or antimicrobial action These products are ideal for daily or weekly cleaning and gentle enough for regular use. Pro Tip: Brands like StoneTech , Granite Gold , or Weiman offer stone-safe disinfectants designed for marble, granite, and more. 2. Use 70% Isopropyl Alcohol – With Caution When stronger disinfecting is needed (such as after exposure to illness), isopropyl alcohol can be used, but carefully. How to use it: Mix 70% isopropyl alcohol with distilled water in a 1:1 ratio. Lightly mist the solution onto the surface. Let it sit for 30 seconds to disinfect. Wipe dry with a soft microfiber cloth. Follow with a pH-neutral stone cleaner to remove any residue and restore shine. Avoid prolonged exposure , and never use alcohol on unsealed stone, as it can dry out or damage the surface. 3. Use Disposable Disinfectant Wipes , Sparingly During peak COVID times, many people turned to disinfectant wipes. While convenient, most contain quaternary ammonium compounds or alcohol, which can harm natural stone over time. If using disinfectant wipes: Test on a small, inconspicuous area first. Wipe the area with water and a soft cloth immediately after use. Don’t use regularly, save for occasional high-risk scenarios. Disinfecting Products to Avoid To prevent damage, do not use the following on natural stone surfaces: Vinegar or lemon juice Bleach or hydrogen peroxide Ammonia or window cleaners Generic antibacterial wipes (e.g., Clorox, Lysol) without rinsing Abrasive scrubbing pads These can etch, dull, discolor, or weaken the protective seal on your stone. Daily Cleaning vs. Disinfection It's important to distinguish between cleaning and disinfecting : Cleaning removes dirt, oils, and debris from the surface. Disinfecting kills bacteria, viruses, and other pathogens. For natural stone, daily cleaning with a pH-neutral cleaner is enough in most households. Reserve disinfecting for situations that truly call for it, such as illness in the home, handling raw meat, or post-exposure to public surfaces. Don’t Forget to Reseal Disinfecting, even with safe products, can gradually wear down your stone’s protective seal. To maintain water and stain resistance: Check your seal every 6–12 months. Reapply a stone-safe sealer if water no longer beads on the surface. This will keep your stone protected and make cleaning (and disinfecting) easier in the long run. Final Thoughts Disinfecting your home shouldn’t come at the cost of damaging your beautiful natural stone surfaces. By choosing the right products and following a few simple precautions, you can keep your stone clean, sanitized, and stunning for years to come. Need help restoring dull or etched stone?
