Can I Use Bleach on Quartz Countertop?

What is Quartz?

Quartz countertops, also known as engineered stone, are made from ground natural quartz crystals combined with resins and pigments. The result is a man-made material that is non-porous, stain resistant, and highly durable.

Is Bleach Safe for Quartz?

Most quartz manufacturers recommend avoiding harsh chemicals like bleach. Here’s why:

Can Damage Sealant

Quartz countertops are sealed to prevent stains and damage. Bleach can break down this sealant over time, causing the countertop to become prone to staining.

Can Cause Discoloration

The resins used in quartz can react with the chlorine in bleach, leading to fading or discoloration on the surface. This damage is permanent.

Voids Warranty

Using bleach on quartz goes against most manufacturer care instructions, which can void any warranty on the countertops.

Recommended Cleaners for Quartz

While bleach is too harsh, quartz countertops are very low maintenance overall. Here are some recommended cleaners:

  • Mild soap and water – For basic daily cleaning, use a soft sponge or cloth with warm water and mild dish soap. Rinse well.
  • Vinegar – For occasional deep cleaning, use a 50/50 mix of water and distilled white vinegar. Rinse thoroughly.
  • Stone cleaner – Use a specialty stone cleaner made for engineered quartz. Avoid anything acidic.
  • Hydrogen peroxide – A mild hydrogen peroxide solution can disinfect quartz without damage.
  • Baking soda – Make a paste with baking soda and water to gently scrub away stuck-on grime.

Proper Care for Quartz Countertops

Follow these tips to keep quartz looking like new:

  • Blot spills quickly to prevent staining
  • Avoid placing hot pans directly on the surface
  • Use cutting boards and trivets to protect from knives and burns
  • Clean with a non-abrasive sponge or soft cloth
  • Reseal if needed every 1-2 years for optimal protection

Can I Use Bleach on Quartz Countertop?

In summary, it is not recommended to use bleach or any chlorine-based cleaners on quartz countertops. The chemicals in bleach can damage and discolor the quartz over time. For routine cleaning, stick to mild dish soap, water, and specialty stone cleaners. With proper care, quartz countertops can stay looking beautiful for many years. Avoid harsh cleaners like bleach that can void the warranty and ruin the appearance of this expensive surface.
