Can You Bleach Quartz Countertops?

Quartz countertops are an increasingly popular choice for kitchen and bathroom remodeling projects. Made from ground quartz crystals mixed with resin and pigments, quartz counters are praised for their durability, low maintenance, and stylish appearance. However, like any countertop material, quartz requires proper care and cleaning to keep it looking its best. This raises a common question – can you bleach quartz countertops?

Should You Use Bleach on Quartz Countertops?

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

  • Bleach can damage the resin binder. While tough, the polymer resins that bind the quartz crystals together can be degraded by harsh chemicals like bleach. This can cause erosion and loss of shine over time.
  • Bleach can discolor quartz. The pigments added to tint quartz can be affected by oxidizing cleaners. This may cause fading or blotchiness in the color.
  • It leaves the counter vulnerable. Bleach removes the protective sealant layer on quartz, allowing stains to penetrate more deeply into the material.
  • Abrasive particles may scratch. Many bleach products contain gritty particles that could scratch the smooth surface when scrubbed.

Recommended Cleaners for Quartz Counters

While bleach is too harsh for quartz, there are many effective cleaners that can keep your counters spotless:

  • Mild soap and water – For regular cleaning, a mild detergent and warm water is usually sufficient. Rinse well and dry with a soft cloth.
  • Glass cleaner – For shining and streak-free results, use a standard glass cleaner. Check the label to avoid ones with ammonia.
  • Hydrogen peroxide – A mild hydrogen peroxide solution can disinfect and remove stains without the risks of bleach. Rinse thoroughly.
  • Baking soda – For scrubbing away tougher grime, make a paste with baking soda and water. Rinse completely afterwards.
  • Vinegar – Help restore shine and remove soap scum by mixing equal parts white vinegar and water. Follow up by wiping with clean water.

Tips for Keeping Quartz Countertops Like New

With regular cleaning and proper care, quartz countertops can stay looking fresh, clean and vibrant for many years. Here are some maintenance tips:

  • Blot spills quickly to prevent staining. Acids like wine or fruit juice can etch quartz.
  • Avoid abrasive pads and powders that could scratch the surface. Use soft cloths instead.
  • Reseal quartz every 1-2 years with a penetrating quartz-specific sealer to protect from stains.
  • Use trivets and cutting boards to minimize direct hot pans on the counter. Quartz can withstand brief exposure.
  • Don’t let soap, toothpaste or cleaning products dry on the counter. Rinse thoroughly after using.

Can Quartz Withstand Any Cleaning Products?

While quartz is very durable, there are still some cleaning agents to avoid using on your counters:

  • No bleach or hydrogen peroxide stronger than 3%.
  • No oven cleaners or drain openers.
  • No acidic or abrasive toilet bowl cleaners.
  • No oil-based soaps, ammonia, or alkaline-heavy degreasers.
  • No nail polish remover or paint strippers like turpentine.
  • No harsh solvents like acetone.


To summarize, quartz counters are prone to damage when cleaned with bleach. For best results, use mild cleaners like soap and water or vinegar solutions. Check cleaner labels to ensure they are non-abrasive and approved for use on engineered stone. With proper maintenance and care, quartz countertops will stay looking like new for many years. Avoiding harsh chemicals like bleach is key to preserving their beauty.

Common Bleach Concerns with Quartz Counters

Bleach is a powerful cleaner and disinfectant, but it should be avoided for quartz countertop cleaning. Here are some of the top reasons why:

  • Bleach contains oxidizing agents that can react with pigments and cause discoloration of the quartz surface over time. This could result in fading, blotchiness, or white spots.
  • The chlorine in bleach can deteriorate the resin binders used in quartz. This binder is what holds the quartz crumbs together to form the solid slab. Deterioration can lead to erosion pits and reduced shine.
  • Bleach removes the protective sealant layer that is applied at the factory during fabrication. This exposes the porous quartz material underneath to potential staining.
  • Bleach has an abrasive effect on surfaces, which can slowly scratch quartz during aggressive scrubbing over many cleanings. These micro-scratches accumulate and worsen appearance.

Safer Cleaning Alternatives for Quartz

Luckily there are many effective and safer options for cleaning quartz countertops without turning to harsh bleach:

  • For routine cleaning, use a mild detergent and warm water applied with a soft sponge or cloth. Avoid abrasive scrubbers.
  • Disinfect quartz using a diluted hydrogen peroxide solution. Hydrogen peroxide won’t fade quartz color like bleach can.
  • For stubborn stains, make a paste with baking soda and water. The soft scrubbing action lifts grime without scratching.
  • Mix equal parts vinegar and water to help eliminate soap scum buildup and restore shine.
  • Look for quartz-safe cleaning products that contain no bleaches, alkalis, acids, or abrasives.

Maintenance Tips for Quartz Countertops

With proper care, quartz countertops can stay looking fresh and damage-free. Here are some tips:

  • Reseal quartz counters every 1-2 years using a penetrating sealer specifically designed for quartz. This prevents stains from setting in.
  • Always use cutting boards, trivets and hot pads. Avoid direct heat or cut marks from knives.
  • Blot up spills immediately, especially fruit juices, wines, and oils that can stain if left to sit.
  • Don’t let cleaning products dry on the surface. Always rinse thoroughly after cleaning.
  • Check cleaner labels and avoid ones containing ammonia, alkaline, acids, or abrasives.

By using gentle cleaners and taking measures to protect quartz surfaces, you can safely keep them sparkling without risking bleach damage. With proper care, quartz countertops can stay looking like new for many years.

FAQs About Bleaching Quartz Countertops

Is it okay to use just a little bleach on my quartz counters?

No, even small amounts of bleach over time can cause discoloration, erosion, and loss of shine on quartz surfaces. It’s best to avoid bleach entirely and use gentler cleaners like hydrogen peroxide and baking soda instead.

What could happen if I accidentally got some bleach on my quartz countertop?

If exposed to bleach briefly, thoroughly rinse the area with water right away. This should prevent permanent damage. Avoid rubbing the area and use a soft sponge instead. Monitor for any signs of discoloration over the next few weeks. Immediately reseal the quartz counter using a penetrating sealer.

Why does bleach damage quartz when it’s supposed to be stain resistant?

While quartz has excellent stain resistance, it is still vulnerable to damage from chemicals. Bleach contains harsh oxidizers and chlorine compounds that can react with quartz’s resin binders and pigments in ways that food and drinks do not.

Are there any household cleaners I should avoid using on quartz besides bleach?

Yes, avoid abrasive cleansers, alkaline degreasers, oven cleaners, acidic toilet bowl cleaners, nail polish removers and oil-based soaps. Vinegar, hydrogen peroxide, glass cleaner, and mild detergent are safer options. Always check the product label.

Is it okay to use bleach to clean the grout lines on my quartz countertop?

No, avoid directing any bleach onto the quartz surface itself. The overspray could lead to discoloration. Use a bleach pen designed just for grout or try steaming the grout lines instead of bleach.

How can I disinfect my quartz counters without bleach or risk of damage?

For disinfection, use a dilute hydrogen peroxide cleaner instead. Rubbing alcohol can also sterilize quartz effectively. Some quartz cleaners also contain natural disinfectants like tea tree oil to kill germs without bleach.

What’s the best way to restore or strengthen my quartz countertop’s factory sealant layer?

Applying a penetrating quartz sealer every 1-2 years will reinforce the existing sealant layer and help protect from stains. Be sure to use a sealer made specifically for quartz and apply according to directions.


Bleach may be an effective cleaner in many situations, but it should never be used on quartz surfaces. The risks of damage are simply too high. With proper care using non-abrasive, quartz-safe cleaners, these durable counters can retain their beauty and function for many years without the need for harsh chemicals. Being mindful to avoid bleach can help your quartz counters look pristine indefinitely.
