Frequently Asked Questions

What is the best way to clean quartz countertops?

For daily cleaning, use a soft cloth with a mild dish soap and water solution, or a pH-neutral cleaner specifically designed for quartz. Avoid abrasive scrubbers or harsh chemicals like bleach or ammonia, as they can damage the surface.

Do quartz countertops need to be sealed?

While quartz is naturally non-porous and highly stain-resistant, applying a sealer can offer an extra layer of protection, particularly for lighter colors or in high-traffic areas. It can enhance stain resistance and maintain the original shine.

How often should I seal my quartz countertops?

Quartz itself does not require sealing in the same way natural stone does due to its non-porous nature. However, if you choose to use a sealant for added protection, reapplication typically isn’t needed for several years. Follow the product manufacturer’s recommendations.

What are common mistakes to avoid when caring for quartz?

Avoid using abrasive cleaners or scouring pads, which can scratch the surface. Do not place hot pans directly on the countertop, as extreme temperature changes can cause damage. Also, be mindful of harsh chemicals like drain cleaners or oven cleaners, which can etch or discolor the quartz.
