Can I Use Clorox on Quartz Countertops?

What is Quartz?

Quartz countertops are made from ground quartz crystals combined with resins and pigments. This combination creates a hard, non-porous surface that is resistant to scratches, stains, and heat.

Unlike natural stone countertops (like granite or marble), quartz does not need to be sealed. The resin binds the quartz particles together to create a waterproof material. This makes quartz an ideal low-maintenance countertop option.

Is Clorox Safe for Quartz?

The short answer is yes, you can use Clorox bleach products to clean quartz countertops in moderation. According to the manufacturer, diluted bleach is safe for routine cleaning of quartz surfaces.

Clorox recommends mixing 3/4 cup bleach per gallon of water. This dilute bleach solution can be used to disinfect and brighten your quartz countertops. Stronger bleach solutions are not recommended, as they could potentially damage the resin binders over time.

It’s important to avoid letting bleach sit or soak on the countertop. Prolonged exposure to concentrated bleach could cause discoloration. Simply apply the diluted solution, let it sit briefly, then rinse thoroughly with clean water.

Best Practices for Cleaning Quartz with Bleach

To safely clean quartz countertops with Clorox bleach products:

  • Always dilute bleach according to the manufacturer’s recommendations – 3/4 cup per gallon of water is ideal for quartz.
  • Apply the diluted bleach solution and let it sit for 5-10 minutes. Avoid letting it soak for longer periods.
  • Agitate with a soft cloth or sponge while bleaching. This helps lift dirt and stains.
  • Rinse thoroughly after bleaching to remove all bleach residue.
  • Blot dry with a microfiber cloth to prevent water spots.
  • Never mix bleach with other cleaners, especially those containing ammonia or acids. This creates toxic fumes.
  • Open windows and turn on fans to ventilate when using bleach.
  • Use bleach sparingly – excessive bleaching can damage the resin binders.
  • Test bleach on an inconspicuous spot first to check for any adverse effects.

Alternative Cleaners for Quartz

While diluted bleach is quartz-safe, you don’t need to use it for every cleaning session. Here are some everyday cleaners that work well:

  • Soap and water – A mild dish soap diluted in warm water effectively cleans most messes on quartz.
  • Vinegar – For hard water spots and soap scum, white vinegar is a natural cleaning option.
  • Hydrogen peroxide – A mild hydrogen peroxide solution also disinfects quartz without the harshness of bleach.
  • Stone cleaner – Look for a specialty stone cleaner made for engineered quartz. Follow the manufacturer’s instructions.

No matter what cleaning solution you choose, be sure to thoroughly rinse and dry quartz countertops to prevent buildup of cleaning agents over time. With proper care, your quartz counters will maintain their good looks for years to come. The key is cleaning regularly with approved cleaners and avoiding prolonged exposure to harsh chemicals like undiluted bleach.

FAQ About Using Bleach on Quartz

Can I clean my quartz countertop daily with Clorox?

No, you should not clean quartz with full-strength bleach daily. Frequent bleaching could damage the resin material over time. Limit bleach cleaning to once a week or less.

What ratio of bleach and water is safe for quartz?

Clorox recommends diluting 3/4 cup bleach in 1 gallon of water. Stronger concentrations increase the risk of discoloration or damage.

What happens if I accidentally leave bleach on my quartz?

Rinse immediately with water. Prolonged bleach exposure can discolor or corrode the surface.

Can bleach damage the finish of quartz countertops?

Yes, with repeated use. Always dilute bleach and limit its use to avoid degrading the resin binders that give quartz its shine.

Is it okay to bleach quartz seams?

Yes, diluted bleach is safe for the seams as long as you promptly rinse it away. Avoid prolonged exposure to prevent seam separation.

Can I mix bleach and vinegar to clean quartz?

No. Never mix bleach and vinegar or other acids, like in bathroom cleaners. This creates toxic chlorine gas.

Is it safe to use bleach wipes on quartz?

Check the concentration first. Some disinfecting wipes with bleach may be too harsh for quartz. Look for “quartz safe” on the label.


Quartz countertops are bleach-resistant with proper care. A diluted bleach-and-water solution effectively kills germs and brightens the surface. Just be sure to dilute bleach appropriately, limit use, rinse thoroughly, and alternate with non-bleach cleaners for the best results. With this proper maintenance routine, quartz counters will withstand daily wear and retain their beauty. Be cautious not to overdo it with harsh chemicals that could degrade the engineered stone over time.
