Care & Maintenance: Natural Stone

Natural Stone

JANUS et Cie uses a diverse mix of natural stone on our collections. Each stone brings its own beauty to the item. Our stone can vary in finish ranging from honed, polish or flamed. There are different levels of porousness in each stone, which can affect the amount of absorption and stain resistance. Some of our more porous materials are reinforced with an epoxy fill.

All of our stones are natural materials that we source from around the world. There can be variations in texture, color, veining, and patterns from one top to another. These differences and disparities are part of what makes the stone beautiful.

Our stone is treated with INTENSIFIATM by Dry-Treat. It is a combination of enhancer and sealer. This gives our stone a deep, long-lasting color enrichment and premium water- and oil-based stain protection. Our sealer does not protect the stone surface from being etched by acidic liquids or materials.

For installations in locations with continuous periods of freezing temperatures, cracks may occur in the natural stone with the expansion and contraction of the top as a result of these weather conditions. Storing your stone top indoors if possible or using a frame cover can help protect it during the off season or when not being used for extended timeframes.

Be wary of extreme changes in temperature as it could possibly damage your stone top. Using trivets and potholders is highly recommended to protect the stone when serving hot dishes. Coasters are also recommended to prevent possible water rings.


  • Use a microfiber cloth to dust off the surfaces.
  • Wash with mild, pH-neutral soap such as Dawn® and clean water using a non-abrasive cloth or sponge.
  • Use of harsh chemicals or abrasive cleaners is not recommended. They can scratch, pit, and etch the surface of the stone.
  • Spills have the potential to stain. Porous stones are more susceptible to soaking up spills, which can discolor their surfaces. Clean spills immediately by wiping with a soft damp cloth.


  • We also recommend regularly cleaning with a stone cleaner formulated with a neutral pH, such as Oxy-Klenza Stone Cleaner (JeC Item #799-40-101-01-00). Please follow manufacturer’s instructions.
  • For stubborn stains on stone, a poultice of ammonia will remove most organic stains from marble. Dampen a paper towel or cloth with ammonia mixed with water, and cover the stain for 24-48 hours to remove. Household baking soda can absorb organic stains as well. Sprinkle the stained area with the baking soda and let it sit for 24-48 hours. Wipe clean and reseal (please refer to instructions below).
  • Stone tops will need to be resealed based on use and environment. Before applying a new coat of INTENSIFIATM sealer (JeC Item #799-40-100-01-00), please make sure your stone top is clean. Follow the manufacturer’s instructions. Depending on usage and location, this may need to be done multiple times a year. Please see your sales specialist for details.
