Can You Use Bleach On A Quartz Countertop?

Quartz countertops are popular in many modern kitchens due to their durability, stylish appearance, and low maintenance. However, like any other countertop material, quartz requires proper cleaning and care to keep it looking pristine. Many homeowners wonder if using bleach to clean or disinfect their quartz countertops is safe or recommended. Here is a detailed look at using bleach on quartz.

What is Quartz?

Quartz countertops, sometimes called engineered stone, are made from ground natural quartz crystals combined with resins and pigments. The quartz provides strength and hardness, while the resins bind the material together.

Some key properties of quartz:

  • Extremely durable and scratch resistant
  • Stain resistant
  • Easy to clean and maintain
  • Does not need regular sealing like natural stone
  • Resists heat, scorching and most household chemicals
  • Comes in a wide variety of colors and patterns

Is It Safe to Use Bleach on Quartz?

Using undiluted, full-strength bleach directly on quartz countertops is not recommended. The harsh chemicals in bleach can damage and discolor the quartz surface over time with frequent exposure.

However, diluted bleach can be safely used occasionally for disinfecting or removing stubborn stains from quartz. The key is mixing the bleach properly to avoid high concentrations coming into contact with the countertop.

Here are some tips on using diluted bleach on quartz:

  • Mix 1 part bleach with 10 parts water to create a 10% bleach solution. This significantly reduces the bleaching power.
  • Spot test the diluted bleach on a small, inconspicuous area first to check for any discoloration.
  • Limit bleach use on quartz to deep cleaning or disinfecting purposes only, not regular everyday cleaning.
  • Rinse thoroughly with clean water and dry with a soft cloth after applying diluted bleach.
  • Never leave undiluted bleach sitting on the quartz surface for more than a few minutes.
  • Consider safer alternatives like hydrogen peroxide or vinegar for regular cleaning needs.

How to Clean Quartz Countertops

For routine cleaning, quartz countertops can be easily maintained using gentle soap and water. Here are some best practices:

  • Wipe down with a soft, non-abrasive sponge or damp microfiber cloth. Avoid abrasive pads.
  • Use a mild soap, dish detergent or stone cleaner. Avoid harsh chemicals.
  • Rinse off any soapy residue thoroughly after cleaning.
  • Blot up spills immediately to prevent stains, especially oils, wine and fruit juices.
  • For dried on stains, use a non-abrasive cleaner like Soft Scrub or Bon-Ami.
  • Disinfect periodically with diluted bleach or hydrogen peroxide solutions.
  • Reseal quartz countertops every 1-2 years with a stone sealer to enhance stain protection.

Can You Use Other Cleaners on Quartz?

Quartz countertops are durable enough to withstand occasional exposure to a variety of common household cleaners and chemicals, including:

  • Vinegar – Helps kill bacteria and remove stains.
  • Hydrogen peroxide – Disinfects and whitens quartz.
  • Ammonia – Removes grease buildup. Use sparingly.
  • Baking soda – Gentle abrasive property cuts through dirt.
  • Window and glass cleaner – Removes surface dust and dirt.

Always spot test cleaners in an inconspicuous area first. Check the product label for any warnings against use on stone surfaces. Avoid prolonged exposure to harsh chemicals.

Stain Removal Tips

If stains occur on quartz, try these solutions:

  • Oils/grease – Dish soap, ammonia, baking soda or degreasing cleaner.
  • Wine – Hydrogen peroxide or diluted bleach.
  • Fruit juice – Baking soda paste.
  • Dried spills – Scrape off gently with a plastic putty knife first.
  • Hard water marks – Vinegar or lime remover product.

Avoid scraping or scouring stains aggressively as it may damage the quartz finish. For stubborn stains, seek help from a professional stone cleaner.

Can You Use Bleach for Other Purposes?

Using diluted bleach solutions is effective for sanitization, mold removal and occasional deep cleaning:

  • Disinfect kitchen countertops, cutting boards, appliances etc.
  • Clean out mold growth in bathrooms and basements.
  • Periodic heavy duty cleaning of floors and walls.

Always take safety precautions – wear gloves, work in a ventilated area, and never mix bleach with ammonia or acids.


An occasional diluted bleach cleaning is generally considered safe on quartz countertops and can help sanitize surfaces and remove stubborn stains with proper precautions. However, harsh undiluted bleach should be avoided as it can cause long-term damage. For routine upkeep, quartz is easily maintained with gentle soap and water. Take care to wipe up spills quickly before they set and stain. With proper care, quartz countertops will retain their beauty and durability for many years.
