Can You Use Bleach and Water on Quartz Countertops?

Quartz countertops are an increasingly popular option for kitchen and bathroom remodels thanks to their durability, stylish appearance, and low maintenance. However, like any surface, quartz countertops require proper cleaning and care to keep them looking like new. This raises the question – can you safely use bleach and water to clean quartz?

What is Quartz?

Quartz countertops, sometimes called engineered stone, are made from ground natural quartz crystals combined with polymer resins and pigments. The resin binds the quartz particles together to form a durable, non-porous surface.

The main benefits of quartz countertops include:

  • Extremely durable – resistant to scratches, stains, heat, and damage
  • Low maintenance
  • Available in a wide variety of colors and patterns
  • Non-porous so does not require sealing
  • Resists mold, mildew, and bacteria growth

The Risks of Using Bleach on Quartz

Bleach is a powerful cleaner and disinfectant. However, it carries some risks when used on quartz:

  • Can Discolor or Etch – Bleach is acidic and can eat away at the resin binders in quartz causing discoloration and rough spots.
  • Voids Warranty – Most quartz manufacturers warn that using bleach and other harsh chemicals will void the warranty.
  • Harsh Fumes – Bleach releases noxious fumes that are unpleasant and unhealthy to breathe.

For these reasons, quartz fabricators and homeowners are often cautioned against using bleach when cleaning quartz countertops.

Recommended Cleaners for Quartz

The good news is quartz can be kept clean and hygienic using safer cleaning solutions:

  • Mild soap and water – For daily cleaning, a mild soap diluted in warm water is usually sufficient.
  • pH-neutral stone cleaner – Look for a cleaner specifically formulated for engineered stone. These won’t etch or discolor the surface.
  • Disinfectant sprays – If disinfecting, use a spray made for quartz rather than bleach. Popular options areCleanAide Disinfectant Spray orMethod Antibacterial Kitchen Cleaner.
  • Baking soda – For stubborn stains, make a paste with baking soda and water. Let sit for 5 minutes before scrubbing and rinsing.

Using Bleach and Water on Quartz

While not recommended, if you need to use bleach on your quartz countertops, follow these precautions:

  • Use sparingly and spot treat only – don’t soak entire surface.
  • Dilute bleach 10:1 with water – 1 part bleach to 10 parts water. Never use full strength.
  • Rinse immediately and thoroughly after bleaching.
  • Never mix bleach with vinegar or other acids.
  • Test on inconspicuous area first to check for discoloration.
  • Avoid getting bleach on seams and edges.
  • Buff with baking soda after to remove residual bleach.

Even diluted, bleach can damage quartz over time. Use only as a last resort when necessary. For routine cleaning, stick to gentler cleaners designed for quartz. With proper care, your quartz countertops will stay looking like new for years.

Frequently Asked Questions About Using Bleach on Quartz Countertops

Can I use bleach and water to clean my quartz countertops daily?

No, you should not use bleach and water as part of your daily or routine cleaning on quartz countertops. The bleach is too harsh and can slowly damage the material. For daily cleaning, use only mild soap and water.

What ratio of bleach to water is safe for quartz?

If you need to disinfect with bleach, use a very diluted solution of 1 part bleach to 10 parts water. Never use full strength bleach or for prolonged periods.

How long should I leave bleach and water on quartz?

If disinfecting with diluted bleach, wipe it on and let sit for no more than 5 minutes before rinsing thoroughly with clean water. Don’t allow bleach to soak on the surface.

What happens if I accidentally spilled bleach on my quartz countertop?

Immediately rinse the area with water to dilute the bleach. Use baking soda and water to scrub out any discoloration. Bleach may permanently etch quartz if left too long.

Can I mix bleach and vinegar to clean quartz?

Never mix bleach and vinegar. This combination creates chlorine gas which is toxic. Always use cleaners separately.

Is it okay to use bleach on Quartz near the seams?

Avoid getting bleach on seams as it can compromise the structural integrity over time. Bleach is more likely to seep into crevices and cause etching.


While bleach can disinfect quartz countertops, it should be used sparingly and diluted with water to avoid damaging the material. For routine cleaning and maintenance, stick to pH-balanced stone cleaners, mild soap and water, or alternate disinfectants designed specifically for quartz. With proper care, your quartz countertops can stay beautiful and sanitary for years to come. Be sure to follow the manufacturer’s care recommendations to avoid voiding the warranty.
