Why does Quartz Prefab Countertops turn yellow?

Quartz countertops are made from a combination of natural quartz stone and synthetic materials, such as resins and pigments, which are bound together under high pressure and heat to create a hard, durable surface. While quartz is generally resistant to staining, chipping, and scratching, it can still be affected by certain factors that may cause it to turn yellow over time.

One common cause of yellowing in quartz countertops is exposure to direct sunlight. UV rays from the sun can break down the resin used in the countertop, causing it to lose its color and become yellowed. This is especially true for lighter-colored quartz countertops, which are more susceptible to yellowing than darker colors.

Another possible cause of yellowing in quartz countertops is exposure to heat. Quartz countertops can withstand high temperatures, but prolonged exposure to heat from hot pots or pans can cause the resin to break down and discolor over time.

Other factors that may contribute to yellowing in quartz countertops include exposure to chemicals, such as bleach or ammonia, and the use of abrasive cleaning products. It's important to follow the manufacturer's recommendations for cleaning and maintenance to avoid damaging the surface of the countertop.

If your quartz countertop has turned yellow, it may be possible to restore its original color with the help of a professional quartz restoration service. However, prevention is the best approach, so it's important to protect your quartz countertop from direct sunlight, heat, and harsh chemicals to keep it looking its best for years to come.
