How to Remove Bleach Stain from Quartz Countertop

Quartz countertops are popular choices for modern kitchens and bathrooms due to their durability, aesthetic appeal, and low maintenance. However, like any other surface, quartz can be susceptible to stains from spills – including bleach. While quartz is less porous than natural stone, bleach can still penetrate the surface and leave behind stubborn stains. Fortunately, with the right techniques and supplies, you can remove a bleach stain from your quartz countertop.

What Causes Bleach Stains on Quartz?

Bleach is a powerful chemical used to whiten and disinfect surfaces. The active ingredient in most bleaches is sodium hypochlorite, which can damage and discolor surfaces upon contact.

On a quartz countertop, bleach can react with the resin used to bind the quartz particles together. This can alter the color and appearance of the countertop surface. Prolonged exposure to bleach can cause etching and permanent damage.

How to Remove a Bleach Stain from Quartz Countertops

Removing a bleach stain from quartz requires using the right cleaning solutions designed to break down and dissolve the bonded sodium hypochlorite. Here are the step-by-step instructions for removing bleach stains from quartz:

Step 1: Act Quickly

Address the bleach stain as soon as possible. The longer the bleach sits on the quartz, the more likely it will penetrate and bond to the surface. Immediately wipe up excess bleach with a paper towel.

Step 2: Mix a Cleaning Solution

Make a cleaning solution of mild dish soap and warm water. Mix a few drops of dish soap with warm water until sudsy. Alternatively, you can use a specialized stone cleaner. Avoid abrasive cleaners.

Step 3: Apply the Solution and Scrub

Dip a soft cloth or sponge into the soapy solution. Gently rub the stain using a circular motion. Apply light pressure as you scrub. This will help break down the bleach stain without damaging the quartz.

Step 4: Rinse and Dry

Once you’ve scrubbed the stained area, rinse it thoroughly with clean water. Make sure to remove all the soapy residue. Blot dry the area with a soft, lint-free cloth. Inspect to see if the stain has lightened or disappeared.

Step 5: Use Baking Soda

If the bleach stain persists, make a paste by mixing baking soda and water. Spread the paste over the stain and let it sit for 15 minutes. Baking soda will help draw out more of the bleach. Rinse and dry the area afterwards.

Step 6: Use Hydrogen Peroxide

Hydrogen peroxide can also help break down stubborn bleach stains. Dip a cloth into undiluted 3% hydrogen peroxide and dab it onto the stain. Let it sit for 15 minutes before rinsing. Be careful, as this can temporarily lighten the quartz color.

Step 7: Sand Down Severe Stains

For a severe stain that persists through other methods, consider lightly sanding the affected area with fine-grit sandpaper. This will remove the top layer of quartz along with the bonded bleach. Be very gentle to avoid scratching the surrounding areas.

Tips for Avoiding Bleach Stains on Quartz

The best way to deal with a bleach stain is by avoiding one in the first place. Here are some useful tips:

  • Always use a cutting board or trivet when working with bleach near quartz. Never place a bleach container directly on the surface.
  • Clean up spills immediately before the bleach can soak in. Have paper towels ready to blot it up.
  • When cleaning with bleach, dilute it appropriately and limit contact time on quartz.
  • Look for bleach-free and oxygen-based detergents as safer alternatives. Spot test new cleaners first.
  • Reseal and polish your quartz countertops every 1-2 years for added protection.

FAQs About Removing Bleach Stains from Quartz

Can I use vinegar to remove a bleach stain from quartz?

No, vinegar is too acidic and can damage or etch quartz surfaces. Stick to mild dish soap, hydrogen peroxide, or stone cleaners specifically formulated for quartz.

What about using lemon juice or baking powder?

Avoid using anything too acidic like lemon juice or citric acid, as these can also damage quartz over time. Baking powder is too abrasive and may scratch the surface.

Will the stained area look different after removing the bleach?

It’s possible for the cleaned area to appear slightly lighter or shinier. This should diminish over time as the quartz is cleaned and resealed. Persistent discoloration may require professional resurfacing.

Can I use a Magic Eraser to remove the stain?

No, Magic Erasers are too abrasive for quartz surfaces. The melamine foam can damage the finish. Stick to soft cloths and non-abrasive cleaners.

How can I prevent this from happening again?

Be more diligent about using trivets and diluting bleach properly. Also reseal your quartz every 1-2 years to protect from stains. Clean spills immediately before they have time to penetrate.


Bleach stains on quartz countertops can be alarming, but with prompt action and the right techniques they can be removed. Begin by acting quickly to wipe up excess bleach, then use dish soap, baking soda, hydrogen peroxide, and some elbow grease to break down the stain. Avoid harsh acidic or abrasive cleaners. With some diligence and care, your quartz countertop can look as good as new again. Be proactive with trivets and resealing to prevent future stains.
