Can I Clean Quartz Countertops with Bleach?

Quartz countertops are an increasingly popular option for kitchens and bathrooms due to their durability, aesthetics, and ease of maintenance. However, like any surface, quartz requires proper care and cleaning to keep it looking its best. Many homeowners wonder if harsh cleaners like bleach can be used safely on quartz. Here is a detailed guide on cleaning quartz countertops with bleach.

An Overview of Quartz Countertops

Quartz countertops, sometimes referred to as engineered stone, are made from ground natural quartz crystals combined with resins and pigments. The result is a non-porous, stain-resistant, and durable surface that retains its shine and appearance with minimal upkeep.

Some key features of quartz countertops:

  • Made from 90-95% ground quartz bound with resins
  • Non-porous so resists staining
  • Harder and more scratch resistant than granite
  • Available in a wide range of colors and patterns
  • Does not require regular sealing like granite
  • Resists heat, scratches, chips and cracks

Unlike natural stone, quartz counters do not need to be sealed. However, proper cleaning is still required.

Can You Use Bleach on Quartz?

The short answer is no, bleach should not be used to clean quartz countertops. While quartz is incredibly durable, prolonged exposure to harsh chemicals like bleach can damage and discolor the surface over time.

Most countertop manufacturers advise against using bleach or alkaline cleaners on quartz surfaces. The combination of bleach and the chemicals used to make quartz can have a corrosive effect and lead to etching or dulling of the surface.

Bleach is a powerful cleaner and disinfectant, but it is simply too abrasive to be used safely on most quartz countertop installations.

Recommended Cleaners for Quartz

Fortunately, quartz countertops do not require harsh cleaners like bleach to keep them looking pristine. Here are the best cleaning solutions to use instead:

Mild Soap and Water

For day-to-day cleaning, a mild soap diluted in warm water is all you need. Dish soap or a small amount of pure liquid soap works well. Use a soft sponge or cloth to gently wipe the surface, rinsing thoroughly. This helps remove dust, grease, and light stains.

pH-Neutral Stone Cleaner

There are specialized stone cleaners available made specifically for engineered stone like quartz. These are pH-neutral to help lift dirt without damaging the finish. Popular brands like Method and StoneTech also make quartz-safe daily cleaners.

Baking Soda and Water Paste

For tough stains, make a paste of baking soda and water. Apply to the stain and let sit for 5-10 minutes before scrubbing and rinsing clean. The abrasiveness of baking soda helps lift grime without damaging the surface.

Vinegar and Water Mix

A mix of equal parts vinegar and water works well to dissolve hard water spots and residue. Use a soft cloth to rub it on and rinse thoroughly. Avoid using vinegar daily as prolonged use can dull the surface.

Tips for Keeping Quartz Countertops Looking Like New

With regular cleaning using the right products, quartz countertops can keep their just-installed shine for years. Here are some extra care tips:

  • Wipe up spills immediately to prevent stains setting in
  • Avoid exposing quartz to excessive heat that can cause cracks or burns
  • Use cutting boards instead of slicing directly on the counter
  • Don’t let oils, wines and acidic foods sit directly on quartz
  • Avoid abrasive pads and cleaners that can scratch the surface
  • Consider a yearly deep clean by a professional stone cleaner

Can You Use Other Bleach Cleaners on Quartz?

It’s important to note that aside from generic bleach, other chlorine-based cleaners and disinfectants also should not be used on quartz. This includes:

  • Clorox Disinfecting Wipes
  • Tilex Mold and Mildew Remover
  • Comet Cleaner with Bleach
  • Lysol Bleach Mold and Mildew Remover

Read the label carefully on any household cleaner before using it on quartz surfaces. Avoid anything containing chlorine, which is used in many bleaches and disinfectants. Stick to cleaners specifically designed for quartz or natural stone instead.

FAQs Related to Cleaning Quartz Countertops with Bleach

Can I use a bleach-based bathroom cleaner on my quartz vanity?

No, any cleaners containing bleach or chlorine should be avoided on quartz surfaces including bathroom vanity tops. Stick to a gentle soap and water solution or a commercial quartz cleaner instead.

I already used some bleach on my quartz counters. Did I ruin them?

Not necessarily. If bleach was only used a handful of times, a professional deep cleaning and re-polishing should restore the quartz to like-new condition. However prolonged bleach exposure can lead to permanent damage.

What about using a diluted bleach solution on quartz?

Even a diluted bleach solution is not recommended for routine cleaning on quartz surfaces. The combination of bleach and other chemicals in quartz can have a negative effect over time.

Can I use bleach to clean around the edges of my quartz backsplash?

No, bleach should be avoided on all quartz surfaces. Use a specialty grout brush with a gentle cleaner to scrub the grout lines instead. Be careful not to let runoff touch the quartz.


While quartz countertops are incredibly durable, using the wrong cleaners like bleach can deteriorate their appearance and damage the surface over time. For regular upkeep, stick to mild soap and water or a pH-balanced stone cleaner. With the proper care, quartz countertops can stay looking fresh and clean for many years without the need for harsh chemicals.
