Can You Clean Quartz Countertops with Bleach?

What is Quartz?

Before diving into cleaning methods, it’s helpful to understand exactly what quartz countertops are made of.

Quartz counters are composed of ground natural quartz crystals combined with polymer resins and pigments. The exact ratio varies by manufacturer, but high-quality quartz typically contains over 90% ground quartz.

Unlike natural stone counters like granite or marble, quartz is non-porous, so it does not require yearly sealing. The resin binds the quartz particles together to form a hard, durable surface that resists scratches, stains, and heat.

Quartz counters are available in a wide array of colors and patterns to suit any kitchen or bath design aesthetic.

The Problem with Using Bleach on Quartz

Bleach is a powerful cleaner and disinfectant. However, there are a few reasons why bleach is not recommended for routine cleaning of quartz countertops:

  • Bleach can discolor quartz over time – The chemicals in bleach can slowly erode and discolor the pigments used to create the colors and patterns in quartz. This discoloration worsens with repeated bleach exposure.
  • It can dull the surface – Bleach is a harsh cleaner that can gradually cause quartz to lose its polished shine. The abrasive ingredients in some bleaches are too strong for daily use.
  • Possible damage to seals – Although quartz itself is non-porous, there are still seams and seals that should not come into prolonged contact with harsh cleaners like bleach. This could compromise the integrity of the countertop over time.
  • Voids any warranties – Nearly all major quartz manufacturers warn against using bleach to clean their products. Doing so can void any warranties that may come with the countertop.

For these reasons, it’s best to avoid bleach when maintaining quartz surfaces. The good news is that quartz can be easily cleaned and disinfected without bleach.

Recommended Cleaning Methods for Quartz

To safely clean and care for quartz countertops, follow these guidelines:

1. Daily Cleaning

For routine daily cleaning, a soft sponge or microfiber cloth with warm water and a small amount of mild soap is all that is needed to keep quartz clean and hygienic. Avoid abrasive scrub pads or scouring powders that can dull the finish.

Be sure to rinse thoroughly and dry with a soft towel to prevent water spots. A squeegee can help speed up drying.

2. Disinfecting

To sanitize quartz without bleach, use a cleaner made specifically for stone surfaces. Look for EPA-registered disinfectants that are non-acidic and bleach-free.

Popular options include Benefect, Lysol, or Simple Green dPro 5 disinfectants. Check the product label to confirm it is safe for engineered stone.

Spray the disinfectant directly on the countertop and allow it to sit for the recommended contact time before wiping dry with a clean cloth.

3. Removing Stains and Residue

For stuck-on messes like food, grease, or hard water marks, use a non-abrasive quartz cleaner to break up and dissolve the substance. Then wipe away with a damp microfiber cloth.

Baking soda can also be made into a paste to gently lift stains without damaging the quartz.

For accidentally scorched areas, lemon juice often helps remove the burnt discoloration.

4. Preventing Damage

Taking a few simple precautions can help your quartz counters retain their flawless look:

  • Use cutting boards and trivets to protect from scratches and burns
  • Clean up spills immediately to prevent staining
  • Avoid exposing quartz to strong chemicals like paint removers or oven cleaners
  • Have quartz counters professionally resurfaced as needed to restore sheen

The Bottom Line

Quartz manufacturers strongly advise against using bleach or other harsh chemicals not specifically formulated for engineered stone. The good news is that with proper daily care and cleaning products made for quartz, you can safely keep your counters clean, stain-free, and looking like new for years without bleach. Using the recommended cleaning methods will help protect your investment and allow you to enjoy the durability and virtually maintenance-free convenience that quartz provides.

Frequently Asked Questions

Can I use a bleach-based bathroom cleaner on my quartz vanity top or tub surround?

No, it’s best to avoid any cleaners containing bleach on quartz surfaces. Even diluted bleach solutions can damage quartz over time. Opt for a natural stone cleaner instead.

What if I accidentally got bleach on my quartz counters?

Rinse the area thoroughly with water right away. Check to see if any discoloration occurred. Avoid further exposure to bleach and consider having a professional restore the quartz if damaged.

Can Clorox wipes be used on quartz?

Most manufacturers advise against using any bleach-containing disinfectant wipes on quartz countertops. The chemicals and abrasives can harm the finish. Use a non-bleach stone cleaner instead.

Why is bleach bad for quartz but not granite?

Granite is porous, so any discoloration from bleach can be sanded out. Quartz’s non-porous surface can’t be sanded, so bleach damage is permanent. Also, granite lacks the resin sealers found in quartz that are vulnerable to chemicals.

What’s the best way to sanitize my quartz counters?

Use a reputable disinfectant spray made specifically for stone surfaces, like Benefect or Lysol Stone. Check that it does not contain bleach. Spray and let sit for the recommended contact time before wiping.


While bleach may seem like an easy way to clean and disinfect quartz countertops, it can ultimately damage and discolor the engineered stone. Quartz manufacturers strongly advise using only approved stone cleaners free of bleach or acidic ingredients. With proper daily cleaning habits and occasional use of non-bleach disinfectants, you can safely care for quartz surfaces without risk of damage that bleach exposure causes over time. Following the recommended guidelines will help preserve the flawless, like-new appearance of your investment.
