Ways to Maintain Marble Granite and Natural Stone

Natural stone, granite and marble can be beautiful additions to any home or office. To protect their beauty and integrity and ensure a long life for your stone features, proper maintenance is critical. Simple everyday care combined with periodic professional cleaning, sealing and maintenance will protect your investment for many years to come.

Know Your Stone

Knowing and understanding the particular needs of your stone countertops or floors can help you get more out of them. Most stone is classified as siliceous stone or calcareous stone. Siliceous stone includes granite, sandstone, bluestone, brownstone, slate and quartzite while calcareous stone includes marble, limestone, onyx and travertine. Siliceous stone is durable and can tolerate mildly acidic cleaning solutions while calcareous stone requires more gentle cleaning solutions.

Routine Cleaning

When your stone needs cleaning, start by removing any loose debris using a dust cloth or mop. If you prefer to vacuum, check that all the parts are in good working condition and that there are no loose attachments that could scratch the stone. Then clean the area using a mild soap-and-water solution. Rinse thoroughly using plenty of water to eliminate soap residue, and dry with a soft cloth. Do not use lemon juice, vinegar or other acidic cleaners on marble, travertine, limestone or onyx, and skip abrasive dry cleaners that could scratch or damage your stone. Never mix bleach and ammonia when cleaning.


Always use coasters under glasses and trivets under hot pots, pans or dishes. Use placemats before placing an object on the counter that could scratch it. Wet stone flooring can be extremely slippery, but you can reduce the risk by using carpet runners in corridors and high-traffic areas.

Professional Sealing and Maintenance

When marble, granite and other natural stone features are installed, they are typically cleaned and sealed. However, the sealant can become worn over time, leaving the stone vulnerable to damage from normal use and cleaning. You’ll need to periodically check your seal by pouring a small amount of water in several places on your stone, and let it sit about 15 minutes. If your seal is worn, the stone will darken as the water becomes absorbed. It will lighten again as the water evaporates, but it’s a good sign that it’s time for a new seal.

Coating sealants are designed to form a protective layer over the stone while penetrating sealants sink into the wood for deeper, longer-lasting protection. We only use penetrating sealants to ensure your stone surfaces are properly protected for longer. All of the sealants we use are safe for food-prep and handling.
