Colors

• Silestone comes in more than 50 color choices, with new colors being added each year. Solid colors are available along with the traditional mottled look. Each piece of stone is unique. Counter Intelligence warns that continuous long-term exposure to direct sunlight can slightly discolor Silestone surfaces.
  
  

Heat Resistance

• While Silestone can withstand moderate temperatures for brief periods of time, too much exposure or exposure to high heat can cause cracks. Use a trivet for hot items and do not place slow cookers or electric skillets directly on the surface to keep your Silestone in good condition.
  
  

Scratch Resistance.

• The quartz in Silestone is naturally scratch-resistant; quartz rates a 7 on the Mohs Hardness Scale. Generally, knives will not scratch Silestone, but the surface can be damaged by excessive force or pressure. This same scratch resistance can dull your knife, so Silestone should not be used as a cutting board.
  
  

Maintenance

• Silestone is nonporous and does not need to be sealed to prevent staining. It is easy to clean up and does not need regular maintenance. Soapy water or a mild household cleaner are good choices for Silestone. According to Counter Intelligence, never use harsh chemicals, abrasive cleaners, oven cleaners or floor strippers on your quartz surface.
