Can I Use Clorox Bleach on Quartz Countertops?

Quartz countertops are an excellent choice for kitchens and bathrooms due to their durability, aesthetics, and ease of maintenance. However, like any surface, quartz requires proper care to keep it looking its best. When it comes to cleaning quartz, many homeowners wonder if common household cleaners like Clorox bleach are safe to use or if they will damage the quartz.

An Introduction to Quartz Countertops

Quartz countertops, sometimes called engineered stone, have become incredibly popular in recent years. Quartz is made from ground natural quartz crystals combined with resins and pigments. This mixture creates an extremely hard, non-porous surface that is resistant to scratches, stains, and heat.

Some key benefits of quartz countertops include:

  • Highly durable and long-lasting
  • Resists stains, scratches, and heat
  • Non-porous so does not require sealing
  • Easy to clean and maintain
  • Available in a wide variety of colors and patterns

Understanding the composition of quartz will help determine the best way to care for and clean these counters.

Is It Safe to Use Bleach on Quartz?

When it comes to keeping quartz counters clean, many people wonder if using bleach is safe or recommended. The short answer is yes, Clorox bleach can safely be used on quartz countertops in moderation.

Here are some key tips on using bleach to clean quartz:

  • Use in Moderation: Avoid excessive exposure to bleach. Occasional use for spot cleaning is fine.
  • Dilute It: Always dilute bleach with water according to label instructions before applying to quartz. Full strength bleach could damage the surface over time.
  • Spot Clean: Use bleach sparingly only on specific problem areas, not for general surface cleaning.
  • Rinse Thoroughly: Rinse quartz several times after bleaching to remove all residue. Residual bleach left on the surface can cause discoloration.
  • Avoid Harsh Scrubbing: Use a soft sponge or cloth to gently wipe the bleached area. Aggressive scrubbing can dull the quartz finish.

When diluted properly and used sparingly, Clorox bleach is generally considered safe for quartz countertops. However, there are some caveats to keep in mind.

Potential Risks of Using Bleach on Quartz

While bleach is approved for occasional use on quartz, excessive or improper bleaching can pose some risks:

  • Discoloration: Prolonged bleach exposure can cause quartz to become dull or discolored over time. Always rinse thoroughly after bleaching.
  • Finish Damage: Aggressive scrubbing with bleach can damage the glossy finish of quartz, causing etched marks and loss of shine.
  • Seam Damage: Bleach could seep into seams and cause adhesive breakdown around quartz joints and seams. Avoid pouring directly on seams.
  • Pitting: Undiluted or excessive bleach use could potentially cause minor pitting of the quartz surface over many years.

To avoid these problems, stick to mild bleach solutions and spot treat only when necessary. Thorough rinsing is key to prevent residue buildup.

Best Practices for Using Bleach on Quartz

Follow these best practices when using diluted bleach as a spot cleaner for quartz counters:

  • Mix a 10:1 water to bleach solution. Check the bleach bottle instructions.
  • Use an old toothbrush or soft cloth to apply bleach only to the problem area. Avoid widespread bleaching.
  • Let the bleached area sit for 1-2 minutes, then thoroughly rinse 3-4 times. Remove all bleach residue.
  • Buff dry with a microfiber cloth and check that the spot is gone. Repeat bleaching if needed.
  • Avoid excessive scrubbing, which can dull the surface. Be gentle when wiping!
  • Rinse your sink and wash any items that contacted the bleach. Avoid bleach residue buildup.
  • Never mix bleach with other cleaners like vinegar or ammonia, which creates toxic fumes.

With careful diluted application and thorough rinsing, using Clorox bleach to occasionally remove stubborn stains from quartz countertops is considered safe. However, frequent heavy-duty bleaching is not recommended.

Safer Alternatives to Bleach for Cleaning Quartz

If you wish to take a more cautious approach, there are safer, bleach-free options for cleaning quartz counters:

  • Mild dish soap – Dilute with warm water to make an effective daily surface cleaner.
  • Vinegar – Helps eliminate bacteria and leaves a streak-free shine.
  • Hydrogen peroxide – Breaks down stains without leaving harsh chemical residue.
  • Baking soda – Creates a gently abrasive paste with water that lifts dirt.
  • Baby shampoo – Used in a spray bottle, provides a natural, non-toxic cleaning option.
  • Store-bought quartz cleaners – Look for specialty cleaners made for engineered stone.

Be sure to read all product labels and test any new cleaner on an inconspicuous spot first. With routine cleaning using non-abrasive soap and water, quartz requires minimal chemical intervention.

When to Seek Professional Help

In most cases, routine cleaning is enough to keep quartz counters spotless. But if stains persist or you notice etching, pitting, or color changes on the surface, it’s best to contact a professional for help. Symptoms of quartz damage may include:

  • Visible scratches, pits, or divots in the surface
  • Stains that reappear shortly after cleaning
  • A foggy, etched look to the finish
  • Water marks or discoloration in isolated areas
  • Soap scum buildup that won’t rinse away

Damaged quartz often requires expert intervention. A pro can polish out minor scratches, resurface etched areas, or suggest a full replacement if damage is beyond repair. Do not attempt do-it-yourself repairs like grinding or resurfacing on quartz.

Maintaining Your Quartz Countertops

With routine cleaning and by avoiding harsh chemicals, it’s possible to keep quartz counters looking like new for years. Here are some maintenance tips:

  • Wipe up spills immediately to prevent stains from setting
  • Clean surfaces daily using a soap/water solution
  • Avoid abrasive cleaners or scouring pads
  • Use cutting boards and trivets to protect from knives and hot pans
  • Reseal quartz every 1-2 years for added protection
  • Professionally restore the finish if etching or dullness occurs

Your quartz provider can advise on the best long-term care plan. With proper maintenance, quartz countertops will stay beautiful and functional for decades.


Quartz offers homeowners an extremely durable, low-maintenance countertop option. When caring for quartz, Clorox bleach can be used sparingly to treat tough stains. However, dilute bleach properly, spot test instead of widespread use, rinse thoroughly, and minimize abrasive scrubbing to avoid any long-term damage. For routine cleaning, non-abrasive detergents and natural options like vinegar and baking soda will keep quartz counters shining like new with minimal chemical exposure. With the proper care, quartz countertops will withstand years of use while maintaining their sleek, modern look.
