What Destroys Quartz Countertops?


Quartz countertops are prized for their beauty, durability, and low maintenance. However, despite their resilience, certain factors can compromise their integrity and appearance over time. Understanding what can damage quartz countertops is essential for maintaining their pristine condition. Here are some key factors to be aware of:

1. High Heat

Quartz countertops are not completely heat-resistant. Exposing them to high temperatures can lead to thermal shock, causing the quartz to crack or discolor. To avoid this, always use trivets or heat pads when placing hot pots, pans, or dishes on the surface.

2. Abrasive Cleaners

Using abrasive cleaners or scouring pads can scratch the surface of quartz countertops. It's best to use mild dish soap and a soft cloth or sponge for regular cleaning. For tougher stains, a non-abrasive cleaner specifically designed for quartz surfaces is recommended.

3. Harsh Chemicals

Chemicals like bleach, ammonia, and strong acids or alkalis can damage the resin that binds the quartz particles together. This can lead to discoloration and weakening of the countertop. Avoid using harsh chemicals and opt for pH-neutral cleaners instead.

4. Prolonged Sun Exposure

Direct and prolonged exposure to sunlight can cause quartz countertops to fade or discolor over time. UV rays can break down the resin, leading to a loss of color and shine. If your countertops are in an area with a lot of natural light, consider using window treatments or UV-protective films.

5. Impact Damage

While quartz is generally durable, heavy or sharp objects can still chip or crack the surface if dropped with force. Be cautious when handling heavy cookware or other items near your quartz countertops to prevent accidental damage.

6. Standing Water

Although quartz is non-porous and resistant to stains, standing water can still cause damage. Water can penetrate any seams or joints, potentially leading to mold or mildew growth. Wipe up spills promptly and avoid leaving wet items on the countertop for extended periods.

7. Improper Installation

Proper installation is crucial for the longevity of quartz countertops. Improperly installed countertops can develop stress points, leading to cracks or other damage over time. Always hire a professional with experience in installing quartz countertops to ensure a flawless installation.

8. Using the Countertop as a Cutting Board

Cutting directly on a quartz countertop can scratch the surface and dull your knives. Always use a cutting board to protect both your countertops and your kitchen tools.


Quartz countertops are an excellent choice for many kitchens due to their beauty and durability. However, they are not indestructible. By understanding what can damage quartz and taking preventive measures, you can keep your countertops looking beautiful for years to come. Remember to use trivets for hot items, avoid harsh chemicals, and clean with non-abrasive products to maintain the integrity and appearance of your quartz countertops.
