Should Windex Be Used on Quartz Countertops?

Using Windex to clean quartz countertops is a debated topic. Here is a detailed look at the pros and cons of using Windex on quartz counters.

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 hard, non-porous surface that is stain, scratch, heat, and acid resistant.

Some key features of quartz countertops:

  • Extremely durable – harder than granite
  • Non-porous – does not need to be sealed
  • Resists stains
  • Easy to clean
  • Available in a wide variety of colors and patterns

Is Windex Safe for Quartz?

Windex is a popular household cleaner made by S. C. Johnson & Son. The original blue Windex contains ammonia as the active cleaning ingredient.

There are a few concerns when using Windex on quartz countertops:

  • Ammonia – While quartz is acid-resistant, concentrated ammonia can potentially dull the surface over time with repeated use.
  • Additives – Some Windex products contain glycol ethers or alcohol which may strip off sealers.
  • Residue – Windex can leave a film or residue on the countertop.

However, when used occasionally and correctly, Windex is generally considered safe for cleaning quartz surfaces.

Best Practices for Using Windex on Quartz

If you wish to use Windex on your quartz countertops, follow these best practices:

  • Test a small inconspicuous area first to check for any damage or residue.
  • Use Windex sparingly – avoid excessive spraying.
  • Use a soft microfiber cloth and avoid abrasive pads.
  • Rinse surface thoroughly after cleaning.
  • Opt for Windex products without additives like vinegar or ammonia. Windex Vinegar-Free Glass Cleaner is a good option.
  • Clean spills quickly to avoid staining.
  • Consider alternating with a quartz-specific cleaner.

Quartz Countertop Cleaning Recommendations

While Windex can be used cautiously on quartz, it’s best to stick to cleaners specifically designed for engineered stone. Here are some do’s and don’ts:


  • Use a pH-neutral quartz cleaner like Hope’s Perfect Countertop Cleaner.
  • Clean spills quickly with a soft cloth and mild soap and water.
  • Rinse thoroughly after cleaning.
  • Use a microfiber cloth to avoid scratches.


  • Use vinegar, ammonia, or alkaline cleaners which can etch/damage sealers over time.
  • Allow spills to sit – clean promptly.
  • Use abrasive pads or scrub brushes.
  • Place hot pans directly on the surface. Use trivets.

FAQs About Using Windex on Quartz

Is it okay to use Windex daily on my quartz counters?

No, you should avoid using Windex daily. Opt for a daily quartz cleaner and only occasionally use Windex for fingerprints or gloss. The ammonia and potential additives with repeated use can damage the countertop over time.

What happens if Windex sits on the quartz?

Leaving Windex to pool or soak into the countertop for an extended time can lead to etching, dulling, and possible discoloration. Always rinse immediately after cleaning.

Is the residue from Windex harmful to quartz?

The streaks or film left by Windex are mostly cosmetic. However, you should thoroughly rinse after using Windex to prevent buildup. Residue can make the countertop appear dull over time.

Can I use Windex on quartz vanity tops and shower walls?

Yes, Windex can safely be used on most quartz surfaces like bathroom vanities and shower walls. Rinse thoroughly and use sparingly to prevent damage. Avoid abrasive scrubbing.

What about using Windex on granite or marble?

Windex is not recommended for use on granite, marble, or other porous natural stone. The ammonia in Windex can etch and damage the unsealed surface. Use a specially formulated stone cleaner.


While Windex is not considered highly damaging to quartz surfaces, it’s best used only occasionally and correctly. Stick to a specialty quartz cleaner for daily cleaning and be sure to rinse thoroughly after using Windex to remove any residue. With proper care, your beautiful quartz countertops will maintain their luster for many years.
