With simple care, engineering stones will retain its radiant, lustrous appearance for many years. For routine cleaning, use a damp cloth or paper towel and, if necessary, a small amount of non-bleach, nonabrasive cleanser.

Even though it's resists permanent staining when exposed to liquids (such as wine, vinegar, tea, lemon juice and soda) or fruits and vegetables, wipe up food and liquid spills as soon as possible.

For stubborn or dried spills, use a nonabrasive cleaning pad such as a white 3M Scotch-Brite®* scrub pad coupled with Formula 409® Glass & Surface Cleaner** or a comparable cleaning product.

Avoid using cleansers that contain bleach. Always follow the cleaner manufacturer's use instructions and exercise proper care when handling and storing any cleaning products.

Clean stone surfaces with a few drops of neutral cleaner, stone soap or a mild liquid dishwashing detergent and warm water. Use a clean rag mop on floors and a soft cloth for other surfaces for best results. Too much cleaner or soap may leave a film and cause streaks. Do not use products that contain lemon, vinegar or other acids on marble or limestone. Rinse the surface thoroughly after washing with the soap solution and dry with a soft cloth. Change the rinse water frequently. Do not use scouring powders or creams; these products contain abrasives that may scratch the surface.

In the bath or other wet areas, soap scum can be minimized by using a squeegee after each use. To remove soap scum, use a non-acidic soap scum remover or a solution of ammonia and water (about 1/2 cup ammonia to a gallon of water). Frequent or over-use of an ammonia solution may eventually dull the surface of the stone.

Vanity tops may need to have a penetrating sealer applied. Check with your installer for recommendations. A good quality marble wax or non-yellowing automobile paste wax can be applied to minimize water spotting.
