Can I Clean My Quartz Countertops With Hydrogen Peroxide?

Cleaning quartz countertops can seem daunting, but with the right techniques and products, you can keep them looking like new. Hydrogen peroxide is one cleaning agent that is sometimes recommended for quartz counters. Here is a detailed look at using hydrogen peroxide to clean quartz.

What is Quartz?

Quartz countertops, sometimes called engineered stone, have become very popular in recent years as an alternative to natural stone surfaces like granite and marble. Quartz is made from ground quartz crystals combined with resins and pigments. The result is a durable, non-porous surface that resists scratches, stains, and heat.

Quartz requires little maintenance compared to other countertop materials. But periodic cleaning is still needed to keep quartz looking its best. Simple cleaning with mild soap and water is usually sufficient for day-to-day care. But for occasional deep cleaning, some specific cleaners may be useful.

Is Hydrogen Peroxide Safe for Quartz?

Hydrogen peroxide is an oxidizing agent that can be an effective disinfectant and stain remover. When used properly, dilute solutions of hydrogen peroxide are generally considered safe for quartz countertops.

However, there are a few cautions to keep in mind:

  • Only use dilute solutions of 3% household hydrogen peroxide. High concentrations can potentially etch or discolor quartz.
  • Avoid prolonged exposure, and immediately wipe up any excess liquid to prevent pooling.
  • Test hydrogen peroxide on a small, inconspicuous area first to check for any adverse effects.
  • Never mix hydrogen peroxide with vinegar, as this creates a corrosive acid.
  • Rinse the surface thoroughly after cleaning.

As long as it is diluted and rinsed off completely, hydrogen peroxide is usually fine for periodic deep cleaning of quartz counters. But for routine daily maintenance, simple soap and water is best.

How to Clean Quartz Countertops with Hydrogen Peroxide

Here are some step-by-step instructions for safely using hydrogen peroxide on quartz countertops:

1. Pre-treat any stubborn stains

If there are any deeply set stains, first try applying some baking soda and water into a paste over the stain. Allow to sit for 5-10 minutes before scrubbing and rinsing. This can help lift stains before using the hydrogen peroxide.

2. Dilute the hydrogen peroxide

Mix 1 part household 3% hydrogen peroxide with 4 parts water. Always use a dilute solution and never apply full-strength hydrogen peroxide directly to the quartz.

3. Apply to counters

Using a soft cloth, apply the diluted hydrogen peroxide liberally across the entire surface of the quartz counters. Avoid any extremely porous areas around sinks.

4. Allow to sit briefly

Let the hydrogen peroxide solution sit on the quartz for 2-3 minutes maximum. This allows it time to work but prevents overexposure.

5. Scrub and rinse

Scrub the hydrogen peroxide solution over the surface using a soft brush or sponge. Make sure to rinse very thoroughly with clean water to remove all residue.

6. Dry and polish

Wipe the quartz counters completely dry with a soft, clean cloth. Finally, polish with a microfiber cloth to restore the beautiful shine.

Benefits of Using Hydrogen Peroxide on Quartz

When used properly, hydrogen peroxide can offer some advantages for deep cleaning quartz:

  • Powerful stain removal – Hydrogen peroxide is an effective stain fighter, helping lift stubborn messes like coffee and juice stains. The bubbling reaction helps release stains.
  • Disinfecting abilities – In dilute solutions, hydrogen peroxide is a mild disinfectant that can sanitize quartz surfaces. This helps kill germs and bacteria.
  • Deodorizing properties – Hydrogen peroxide has mild bleaching powers that can freshen and deodorize quartz countertops. This eliminates odors left behind from food prep.
  • No harsh fumes – Unlike other strong cleaners like bleach, hydrogen peroxide has no pungent fumes when used. This makes it more pleasant to work with.
  • Environmentally friendly – When used properly, hydrogen peroxide poses less risk of pollution or harm compared to some stronger commercial cleaners.

Alternative Cleaners for Quartz Countertops

If you prefer not to use hydrogen peroxide, some other good options for deep cleaning quartz counters include:

  • Vinegar – Equal parts vinegar and water make an effective cleaner. Use sparingly and avoid prolonged exposure. Never mix vinegar and hydrogen peroxide.
  • Mild soap – Dish soap diluted in warm water can remove most dirt and stains with minimal scrubbing.
  • Baking soda – Form a paste with baking soda and water to gently scrub away messes. Rinse thoroughly.
  • Ammonia – A few drops of ammonia in water cuts through grease and grime. Work in a well-ventilated space and rinse completely.
  • Commercial quartz cleaners – Look for cleaners specifically formulated for quartz and granite. Avoid overly abrasive products.

How Often Should Quartz Countertops Be Cleaned?

For routine care, quartz counters only need cleaning once a week or so with mild soap and water. Spills should be wiped up promptly when they occur.

Deep cleaning with hydrogen peroxide or alternative cleaners should be done every 1-2 months, depending on usage. Clean more frequently in the kitchen, where counters see heavier use. Also deep clean whenever significant stains appear that regular cleaning can’t remove.

With proper maintenance, quartz countertops can stay looking like new for many years. Consistent care and avoidance of damage will help preserve their beauty and function.

Frequently Asked Questions About Cleaning Quartz Countertops

Can I use bleach or other harsh chemicals on quartz counters?

No, avoid using bleach, oven cleaners, drain cleaners, and acidic products like toilet bowl cleaners on quartz. They can etch and discolor the surface. Mild cleaners are best for routine cleaning.

How can I remove dried food stains?

Gently scrape off any hardened material, then apply a paste of baking soda and water to help lift the stain. Scrub and rinse thoroughly with clean water. For stubborn stains, diluted hydrogen peroxide can also help remove discoloration.

Is it okay to cut food directly on quartz counters?

Yes, quartz holds up well against knives for food prep. But using a cutting board will help keep your counters pristine and avoid dulling your knives. Immediately wipe up any liquids or oils from food that spill.

Can hot pots and pans damage my quartz?

Quartz is heat resistant, but prolonged direct heat exposure may damage the surface. Always use trivets or hot pads when setting hot cookware on quartz. Avoid subjecting the counters to temperatures above 150°F.

How do I get rid of water marks or hazy areas on my quartz?

Hard water minerals and cleaning product residues can leave cloudy spots on quartz. Use diluted hydrogen peroxide, vinegar, or ammonia to help dissolve and remove the haze, then rinse thoroughly.


Hydrogen peroxide, when properly diluted and used with care, can be an effective cleaner for quartz countertops. It has stain-fighting power and disinfecting abilities. But be sure to rinse thoroughly and limit exposure time. For routine cleaning, simple dish soap and water are best. With regular maintenance, quartz counters will retain their sparkling look and durability for many years. Employ smart cleaning habits to protect your investment and keep your kitchen looking its very best.
