Can You Use a Bleach Solution on Quartz Countertops?

Quartz countertops are an increasingly popular choice for kitchen and bathroom remodels due to their durability, aesthetics, and low maintenance. However, like any surface, quartz requires proper care and cleaning to keep it looking its best. Some homeowners wonder if using bleach or other harsh chemicals is safe for cleaning quartz. Here is a detailed overview of whether you can use a bleach solution on quartz countertops.

What is Quartz?

Quartz countertops, sometimes referred to as engineered stone, are made from ground natural quartz crystals combined with resins and pigments. The result is a non-porous, highly durable surface that is resistant to scratches, stains, and heat.

Some key features of quartz countertops:

  • Extremely durable and scratch-resistant surface
  • Non-porous so resists staining
  • Available in a wide variety of colors and patterns
  • Does not require regular sealing like natural stone
  • Resists heat damage
  • Easy to clean and maintain

Is it Safe to Use Bleach on Quartz?

Most quartz manufacturers recommend avoiding harsh chemicals like bleach when cleaning quartz surfaces. The main reason is that the abrasive nature of bleach can damage the glossy finish over time.

However, using a diluted bleach solution is generally considered safe for periodic deep cleaning. The key is dilution and not using full-strength bleach directly on the countertop.

Here are a few tips for safely using diluted bleach on quartz:

  • Dilute bleach with water at a 10:1 ratio (10 parts water to 1 part bleach). Never use full-strength bleach.
  • Limit bleach cleaning to occasional deep cleaning, not daily cleaning.
  • Rinse surfaces thoroughly after bleaching and re-seal quartz every 1-2 years.
  • Spot test a small inconspicuous area first to check for any adverse effects.
  • Avoid prolonged exposure and do not allow bleach solution to pool on quartz surfaces.

With proper dilution and rinsing, occasional use of bleach can help remove stubborn stains and disinfect quartz countertops without damaging the surface.

Cleaning Quartz Countertops

For routine daily cleaning, quartz manufacturers advise using mild soap and water or a specialty stone cleaner. Here are some best practices for keeping quartz counters clean:

  • Wipe up spills immediately to prevent stains.
  • Clean with mild dish soap diluted in warm water and a soft cloth or sponge.
  • Rinse well after cleaning.
  • Blot up excess water to reduce streaks and water marks.
  • For best results, use a cleaner made specifically for stone surfaces.
  • Thoroughly clean quartz 1-2 times per week.
  • Avoid abrasive cleaners, pads, and paper towels that can scratch.

Periodic deep cleaning with diluted bleach can help remove stains, disinfect surfaces, and brighten the appearance of quartz. But for routine maintenance, stick to mild cleaners.

Protecting Quartz Countertops

Taking steps to protect quartz can help prevent damage that requires the use of harsh cleaners like bleach. Here are some tips:

  • Use cutting boards, trivets and hot pads to protect from knives and hot pans that can scratch and scorch quartz.
  • Apply a penetrating quartz sealer every 1-2 years to boost stain resistance.
  • Immediately wipe up any spills, particularly oils, wine, and juice that can stain if left to set.
  • Avoid harsh chemicals like paint removers, oven cleaners, etc. on quartz surfaces.
  • Select high-quality quartz that contains upwards of 90% quartz material for better durability.

Can You Use Other Disinfectants on Quartz?

In addition to diluted bleach, there are other disinfectants considered safe for use on quartz countertops:

  • Hydrogen peroxide – Breaks down into water and oxygen. Rinse surfaces after disinfecting.
  • Vinegar – Has disinfectant properties. Mix with water for cleaning quartz. Avoid prolonged exposure to avoid etching.
  • Rubbing alcohol – Dissolves residues. Avoid prolonged exposure to prevent drying out quartz.
  • Lysol or other quaternary ammonium disinfectants – Non-abrasive and approved for use on quartz surfaces.

Always spot test disinfectants first and limit their use to occasional deep cleaning sessions. For day-to-day cleaning, stick to mild detergent and warm water.

Can You Use a Bleach Solution on Quartz Countertops? – Key Takeaways

  • While harsh, full-strength bleach can damage quartz over time, diluted bleach is generally safe for periodic disinfecting when mixed 10:1 with water.
  • For routine cleaning, use mild soap and water. Avoid abrasive pads or paper towels.
  • Always rinse quartz thoroughly after using bleach solutions to prevent residue buildup.
  • Limit bleach cleaning to occasional deep cleaning sessions, not daily wiping.
  • Other disinfectants like hydrogen peroxide, vinegar, and Lysol can also be used safely on quartz counters when following manufacturer guidelines.
  • Take steps to protect quartz from scratches, scorching, and stains by using cutting boards, trivets, and sealing regularly.

With proper care and cleaning, quartz countertops can remain beautiful and sanitary for years before a bleach solution would ever be required. But when disinfecting is needed, a diluted bleach cleaner can safely deep clean and brighten quartz surfaces. Just be sure to dilute it properly, limit frequency of use, rinse thoroughly, and re-seal quartz regularly.

Frequently Asked Questions About Using Bleach on Quartz Countertops

Can I use bleach wipes on my quartz countertop?

Bleach wipes are not recommended as they contain harsh, undiluted bleach that can damage the quartz surface over time. For occasional disinfecting, make your own diluted bleach solution instead.

How long should I leave the diluted bleach solution on quartz surfaces?

Do not allow diluted bleach solution to remain on quartz for more than 5 minutes. Rinse thoroughly with clean water immediately after cleaning. Prolonged exposure can cause discoloration and erosion of the surface.

What ratio of bleach to water is safe for quartz?

Most manufacturers recommend diluting bleach at a 10:1 ratio, or 10 parts water to 1 part bleach. Never use full strength bleach directly on quartz counters.

Can repeated bleaching ruin my quartz countertops?

Yes, frequent bleaching especially with concentrated solutions can damage quartz over time. Limit bleaching to occasional deep cleaning no more than once per month. For daily cleaning, stick to mild detergents.

Is it absolutely necessary to reseal quartz after using bleach on it?

It is a good idea to reseal quartz after deep cleaning with bleach. The bleach solution can break down sealants more quickly. Resealing every 1-2 years will boost stain protection.

What happens if I accidentally spilled concentrated bleach on my quartz?

Immediately rinse the surface thoroughly with water to dilute the bleach. Then, clean with a quartz cleaner and reseal the area to prevent long-term damage like discoloration or etching. Avoid further bleach exposure.


Quartz countertops are a low-maintenance yet stylish surface for kitchens and baths. While harsh chemicals like bleach should be avoided for daily cleaning, diluted bleach can occasionally provide a deep clean and disinfection of quartz. By limiting bleach use, diluting it properly with water, rinsing thoroughly, and resealing quartz regularly, homeowners can safely and effectively incorporate bleach into their quartz cleaning routine. With the proper care, quartz countertops will retain their beauty while staying hygienic in high-use areas like kitchens.
