Is Hydrogen Peroxide Safe to Use on Quartz Countertops?

Hydrogen peroxide is a commonly used household cleaner known for its disinfecting and whitening properties. When used properly, hydrogen peroxide can be safe for cleaning quartz countertops. However, there are a few precautions to take when using hydrogen peroxide on this stone surface.

An Overview of Quartz Countertops

Quartz countertops are engineered stone surfaces made from ground quartz crystals combined with resins and pigments. They are an increasingly popular option for kitchens and bathrooms because they are durable, non-porous, and low maintenance. Here are some key features of quartz countertops:

  • Made from 90-94% ground quartz bound together with resins and pigments
  • Non-porous so they don’t require sealing
  • Resistant to stains, scratches, heat, and acids
  • Easy to clean and maintain
  • Available in a wide variety of colors and patterns

Quartz is less prone to damage than other natural stone surfaces. However, it’s still important to avoid exposing quartz counters to chemicals that can eat away at the resin binders.

Is Hydrogen Peroxide Safe for Quartz?

Hydrogen peroxide can be used safely on quartz counters in dilute concentrations. Here are some tips for safe usage:

Use Proper Dilution

  • For daily cleaning, use a 3% hydrogen peroxide solution diluted with water at a 1:4 ratio.
  • For disinfecting and removing stains, a slightly stronger 10% solution diluted to 1:10 with water is safe.
  • Never use hydrogen peroxide at full strength (35% concentration) as it can damage the resin.

Spot Test First

  • Try hydrogen peroxide on a small inconspicuous area first to check for any discoloration or other reactions.

Avoid Prolonged Exposure

  • Only leave hydrogen peroxide on the quartz surface for 1-2 minutes before wiping away.
  • Rinse thoroughly with water after cleaning.
  • Don’t allow spills or cleaning solution to pool on the countertop.

Use Non-Abrasive Tools

  • Use a soft sponge or microfiber cloth to gently apply and wipe away the hydrogen peroxide solution.
  • Don’t use abrasive scouring pads, which can scratch the surface.

Benefits of Using Hydrogen Peroxide on Quartz

When used properly, hydrogen peroxide offers some advantages for cleaning quartz countertops:

  • Disinfects – Hydrogen peroxide is a mild disinfectant that can kill bacteria and viruses. This helps keep quartz counters hygienic.
  • Removes stains – It can lift stains from coffee, wine, grease, and other spills on quartz surfaces.
  • Whitens – The bubbling reaction helps release dirt from the surface and can gently whiten and brighten quartz.
  • Leaves no Residue – Hydrogen peroxide breaks down into water and oxygen, so it doesn’t leave any chemical residue on the countertop.
  • Environmentally-friendly – It’s a more eco-friendly cleaner compared to harsh chemical cleaners.

So in short – yes, hydrogen peroxide is generally safe for quartz counters as long as you dilute it properly, spot test first, limit exposure time, and use gentle application. It’s best to avoid other harsh oxidizing cleaners like bleach. Be sure to rinse the surface thoroughly after cleaning with hydrogen peroxide. With some care taken, hydrogen peroxide can be an effective cleaner for quartz countertops.

Frequently Asked Questions about Using Hydrogen Peroxide on Quartz Countertops

Can I use 35% food-grade hydrogen peroxide on my quartz countertop?

No, 35% hydrogen peroxide should never be used undiluted on quartz countertops as it can damage the resin binders in the stone. Always dilute food-grade hydrogen peroxide to no more than 10% concentration with water for cleaning quartz surfaces.

How long can I safely leave hydrogen peroxide on my quartz countertop?

Only leave diluted hydrogen peroxide on for 1-2 minutes before rinsing thoroughly with water. Prolonged exposure, especially with higher concentrations, can cause discoloration or etching on quartz.

What ratio of hydrogen peroxide to water is best for cleaning quartz?

For regular cleaning, a 1:4 dilution (3% hydrogen peroxide : water) is ideal. For stain removal, you can use a slightly stronger 1:10 dilution (10% hydrogen peroxide : water). Always spot test first.

Can I mix hydrogen peroxide with other cleaners like vinegar or ammonia to clean quartz?

No, never mix hydrogen peroxide with acidic cleaners like vinegar or basic cleaners like ammonia. This can create a chemical reaction and hazardous byproducts. Always use hydrogen peroxide separately.

How often can I use hydrogen peroxide to clean my quartz countertops?

You can safely use properly diluted hydrogen peroxide to clean quartz counters several times per week. But don’t over-clean quartz with hydrogen peroxide daily, as this may eventually dull the surface over time.

What precautions should I take when using hydrogen peroxide on quartz?

  • Spot test on a small area first
  • Dilute properly with water
  • Limit exposure time to 1-2 minutes
  • Rinse surface thoroughly after cleaning
  • Use a soft sponge or cloth – no abrasive pads


Hydrogen peroxide is generally considered a safe cleaning agent for quartz countertops when used correctly. By diluting it properly with water, limiting exposure, and rinsing thoroughly, hydrogen peroxide can disinfect, brighten, and remove stains from quartz surfaces without damaging them. However, always spot test first and take care not to overuse hydrogen peroxide, as prolonged exposure can potentially dull quartz over time. With some basic precautions, hydrogen peroxide in the right concentrations can keep quartz counters clean and hygienic.
