Silestone® isn’t recommended for outdoor use because UV rays can damage the surface. Long-term exposure to direct sunlight can cause discoloration. Instead, choose an outdoor-friendly countertop material like tile, concrete, stainless steel, or natural stone. If you do choose a natural stone, make sure you either seal it or avoid highly porous stones. For example, choose soapstone over marble.

Avoid using abrasive cleansing powders on natural stone, as these products could damage the porous material. Using bleach is also a poor idea because of the porosity of the stone. Avoid using a scrub brush with metal bristles, as they could scratch the stone. If you know who manufactured your stone or who installed the fireplace, you may want to contact that entity for any advice on cleaning it safely.

Use pH-neutral cleaners specifically designed for stone surfaces to clean granite or marble. Avoid acidic or abrasive cleaners that can damage the sealant or the stone itself. Regular re-sealing helps protect the surface from stains and damage.

Granite should be resealed every 12 to 18 months, depending on the color and usage. Lighter granite needs to be resealed more frequently than darker colors. If you use acidic cleaners or prepare food on the surface regularly, you must reseal the surface more frequently. Without proper sealing, granite is vulnerable to staining. You can tell if your countertop needs to be resealed by placing a wet paper towel on the counter for 10 minutes. If the water beads up, it is still sufficiently sealed; if it sinks in, it’s time to apply sealant.
