Can I Use Bleach on My Quartz Countertops?

Quartz countertops are popular in many homes today thanks to their durability, aesthetics, and low maintenance. However, like any surface, quartz countertops require occasional cleaning to keep them looking their best. Some homeowners wonder if harsh cleaners like bleach can be used safely on quartz. Here’s what you need to know about using bleach on quartz countertops.

Can Bleach Be Used on Quartz Countertops?

The short answer is yes, you can use bleach to clean quartz countertops in small amounts. Most quartz manufacturers say that occasional use of diluted bleach will not harm or discolor quartz surfaces.

However, there are some important caveats to keep in mind:

  • Only use bleach sparingly. Frequent bleaching may cause discoloration over time. Stick to milder cleaners for daily cleaning.
  • Dilute bleach before using. Mix 1 part bleach with 10 parts water. Full-strength bleach could etch or discolor the surface.
  • Spot test first. Dab a small amount of diluted bleach on an inconspicuous area and let sit 10 minutes. If no damage occurs, it should be safe for general use.
  • Rinse thoroughly. Wipe up all bleach residue after cleaning to prevent buildup.
  • Avoid cleaners with higher concentrations of bleach. Stick to plain 5-6% household bleach solutions.

Best Practices for Using Bleach on Quartz

If you do opt to use diluted bleach when cleaning your quartz countertops, follow these best practices:

Check Your Quartz Manufacturer’s Care Guidelines

  • Not all quartz is created equal. Some brands may approve bleach while others prohibit it. Check what your manufacturer recommends before proceeding.

Limit Bleach Use to Occasional Disinfecting

  • Save bleach for deep cleaning just a few times per year. Use a mild soap-and-water mix for day-to-day cleaning.

Mix a Dilute Bleach Solution

  • Combine 1 part bleach with 10 parts cool water. Never use full-strength bleach.

Spot Test on an Inconspicuous Area First

  • Apply a few drops of diluted bleach and let sit for 5-10 minutes. If no damage occurs, it should be safe to use.

Work in Small Sections

  • Clean only a few square feet at a time to avoid the bleach drying on the surface.

Rinse Thoroughly After Cleaning

  • Wipe up all bleach residue with clean water and dry with a soft cloth. Residual bleach can lead to buildup and discoloration over time.

Consider Alternatives for Routine Disinfecting

  • For an everyday disinfectant, use a hydrogen peroxide-based cleaner instead of bleach. It’s gentler on quartz.

How to Clean Quartz Countertops Without Bleach

If you wish to keep bleach away from your quartz entirely, don’t worry – there are other effective cleaning options:

  • Soap and water – For basic everyday cleaning, use a few drops of mild dish soap in warm water. Avoid harsh detergents.
  • Vinegar – A 50/50 vinegar and water solution helps remove grime and leaves a streak-free shine.
  • Hydrogen peroxide – As a gentle bleach alternative, use a 3% hydrogen peroxide solution.
  • Ammonia – When diluted with water, household ammonia cleans and disinfects quartz surfaces.
  • Baking soda – Its mild abrasive properties help scour away dried-on messes. Make a paste with water.
  • Glass cleaner – For hard water spots and greasy buildup, spray quartz with glass cleaner and wipe clean.

No matter which cleaning solution you use, wipe the countertops thoroughly afterward to prevent residue buildup. Avoid abrasive scouring pads that could scratch the quartz. With proper care and maintenance, your quartz counters will stay looking like new for many years.

FAQs About Using Bleach on Quartz Countertops

Can I use bleach wipes on quartz?

Bleach wipes are not recommended, as letting bleach solutions sit for prolonged periods increases the chances of damage to the quartz. The bleach in wipes stays wet against the surface. For occasional disinfecting, use a diluted bleach solution that is promptly wiped dry.

How long can diluted bleach sit on quartz?

When spot cleaning with diluted bleach, wipe it off and rinse the quartz thoroughly after 5-10 minutes maximum. Do not allow bleach to puddle or dry on the countertop, as this can lead to discoloration.

What ratio of bleach to water is safe for quartz?

Most manufacturers advise using a 10:1 water to bleach solution. Mix 1 part regular 5-6% bleach to 10 parts cool water. Stronger bleach concentrations increase the risk of etching or fading.

Can I use bleach pens on quartz countertops?

Bleach pens contain gel bleach at a higher concentration than recommended for use on quartz. They allow concentrated bleach to sit on the surface. For this reason, it’s best to avoid bleach pens and stick to wiped-on diluted solutions instead.

Will a few drops of bleach damage my quartz?

A small amount of diluted bleach applied briefly just for spot cleaning is unlikely to harm quartz. However, leaving full-strength bleach on the surface for an extended time can damage the material. Always test a small inconspicuous area first.

What’s the best way to routinely disinfect quartz?

For regular disinfecting, use a spray cleaner containing hydrogen peroxide rather than harsh bleach. Hydrogen peroxide solutions are powerful disinfectants that are gentle on quartz. Be sure to rinse and dry thoroughly after cleaning.


While bleach can technically be used on quartz countertops in diluted amounts for occasional deep cleaning, it’s best used sparingly. For routine disinfecting and everyday cleaning, gentler alternatives like hydrogen peroxide and soap and water are recommended. Always be sure to spot test bleach on an inconspicuous area first and rinse thoroughly after use. With the proper care, your beautiful quartz countertops will maintain their good looks for many years to come.
