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.

Due to the acidity, using vinegar to clean quartz countertops can actually damage them. In fact, doing so can cause discoloration and surface damage in the quartz. While it’s possible to clean other countertops, like laminate, tile, and butcher block, with vinegar, it’s best to stay from this cleaning solution if you have quartz in your kitchen or bathroom.

While quartz is highly stain-resistant, it is not completely stain-proof. Spills, including water, should be wiped up as soon as possible to prevent staining. Minor stains are usually not permanent and can be removed using a quartz-safe cleaner, a simple mixture of dish soap and water, or a baking soda paste applied with a soft microfiber cloth. For severe stains that persist, professional treatment may be necessary, and in rare cases, countertop repair or replacement might be required.

Since marble is a porous material, it is more prone to water spots than other countertop options. Fortunately, pure water doesn’t damage your marble, but if the water is acidic, it can cause stains or water spots. Resealing throughout the year can help increase marble’s water resistance, too.
