Can Bleach Be Used on Quartz Countertops?

Quartz countertops are popular options for kitchens and bathrooms due to their durability, aesthetics, and low maintenance. However, like any surface, quartz can get dirty over time. Some homeowners may wonder if using bleach is an effective cleaning method for quartz. Here is a comprehensive guide on whether bleach can be used on quartz countertops.

What is Quartz?

Quartz countertops, sometimes referred to as engineered stone, are made from ground quartz crystals combined with resins and pigments. The exact composition varies by brand and product line, but quartz typically makes up over 90% of the material.

The resins bind the quartz particles together to form a hard, non-porous surface. The pigments add color and pattern. Once formed into slabs, quartz is sealed to prevent staining and increase stain resistance.

Benefits of Quartz Countertops

There are several reasons why quartz countertops are popular:

  • Durability – Quartz is very hard and scratch resistant. It can withstand heavy usage in kitchens.
  • Stain Resistance – The non-porous surface makes quartz resistant to stains. Liquids and spills sit on top rather than absorbing into the material.
  • Low Maintenance – Quartz requires very little maintenance compared to other surfaces like marble. Simple cleaning is enough for most homes.
  • Aesthetics – Quartz comes in a wide array of colors and patterns. The look can mimic natural stone or have a more modern vibe.
  • Hygienic – The nonporous surface inhibits bacteria growth. This makes quartz a hygienic choice.

Can You Use Bleach on Quartz?

The short answer is no, bleach should not be used to clean quartz countertops. Here’s why:

  • Harsh Chemicals – Bleach contains harsh chemicals like chlorine that can damage the resin binders in quartz. This can deteriorate and eat away the material over time.
  • Loss of Shine – Bleach is abrasive and can slowly cause quartz to lose its polished shine. It strips away the top sealant layer.
  • Color Change – For quartz with darker pigments, bleach can react with the dyes and cause discoloration or fading. Lighter quartz may yellow from bleach.
  • No Benefit – Quartz is stain-resistant, so bleach provides no cleaning benefit over routine maintenance. The risks outweigh any potential rewards.

Recommended Cleaning Methods

While bleach should be avoided, quartz countertops are very easy to keep clean:

  • For daily cleaning, wipe down with a soft cloth and mild soap and water. Rinse well and dry.
  • For food stains or dirt build up, use a non-abrasive cleaner made specifically for stone surfaces. Look for “quartz-safe” on the label.
  • For stubborn stains, apply a small amount of glass cleaner or hydrogen peroxide. Rinse immediately.
  • Thoroughly dry after cleaning to prevent water spots. Use a squeegee on larger surfaces.
  • Reseal quartz every 1-2 years with a quartz-safe sealant to maintain protection.

What About Other Stone Surfaces?

Since bleach is too harsh for quartz, it should never be used on more delicate natural stone like marble or granite. The porous surfaces will quickly absorb the chemicals leading to etching, discoloration, and accelerated wear.

Other engineered surfaces like solid surfaces (Corian) or laminate can also be damaged by bleach over time. Always check the manufacturer’s care guidelines before using any cleaning products.

Can Bleach Be Used to Remove Stains from Quartz?

If a stain develops on quartz, bleach will not effectively remove it. The stain is likely from a spilled liquid that has penetrated beneath the surface due to an unsealed area or etching.

To remove stains:

  • Try cleaning with a stain remover made for quartz or poultice powder. This draws out deep stains.
  • For tough stains, wet sanding and repolishing may be needed. Consult a stone restoration specialist.
  • Avoid using harsh chemicals like bleach or paint removers that will further damage the quartz.

Signs Your Quartz May Be Damaged from Chemicals

If you have used bleach or other harsh cleaners on your quartz, be on the lookout for these signs of damage:

  • Loss of shine and luster
  • Etching (rough, pitted areas)
  • Cracks or divots in surface
  • Changed or faded coloration
  • Stains that reappear shortly after cleaning
  • Increased porosity with liquids absorbing rather than beading up

How to Care for Quartz Countertops

Caring for your quartz properly keeps it looking like new for many years:

  • Use trivets and cutting boards to protect from hot pans and food prep.
  • Clean up spills immediately to prevent setting.
  • Avoid abrasive pads, scouring powder, or alkaline chemicals.
  • Reseal every 1-2 years with a quartz sealer.
  • Use only quartz-safe cleaners recommended by manufacturer.
  • For matte finish quartz, use a cleaner made specifically for that texture.

FAQ About Using Bleach on Quartz

Can I use just a little bleach to clean my quartz?

No, even small amounts of bleach over time can damage quartz surfaces. It’s best to avoid it altogether.

What if I accidentally got bleach on my quartz?

Rinse the area thoroughly with water to dilute the bleach. Check for any immediate damage like change in shine or discoloration. Avoid further exposure to harsh chemicals.

Can’t I just bleach stubborn stains on my quartz?

Bleach will not effectively or safely remove stains from quartz. Use a poultice method or consult a professional to treat difficult stains.

I prefer the smell and feel of bleach when cleaning. What are the alternatives?

Opt for cleansing quartz cleaners that contain no bleach but still provide disinfecting properties. Or add a few drops of lemon essential oil to your soap and water for a fresh, clean scent.

Will a little bleach really damage my quartz that quickly?

Yes, bleach can begin degrading and etching quartz with even minimal use. Always play it safe and avoid bleach with quartz countertops.


Quartz offers an attractive, low maintenance countertop option, but bleach should never be used during cleaning. The harsh chemicals in bleach can damage quartz over time degrading the appearance and structure. Fortunately, quartz can be easily kept clean and beautiful with gentle soap and water and quartz-safe cleaners. Taking proper care will allow quartz countertops to stay looking like new for many years.
