Can You Use Windex Multi Surface on Quartz Countertops?

Quartz countertops are popular in many homes today due to their durability, ease of maintenance, and stylish appearance. However, it’s important to clean quartz properly to keep it looking its best. Using the wrong cleaning products can damage the quartz surface. So, can you use Windex Multi-Surface on quartz countertops?

An Overview of Quartz Countertops

Quartz countertops, sometimes called engineered stone, are made from ground quartz crystals combined with resins and pigments. The result is a very hard, non-porous surface that resists scratches, stains, and heat.

Here are some key features of quartz countertops:

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

The Potential Risks of Using Windex on Quartz

Windex Multi-Surface Cleaner is formulated to clean a variety of surfaces around the home. However, some ingredients in Windex may pose risks when used on quartz countertops:

  • Ammonia – Quartz countertop manufacturers caution against using cleaners containing ammonia. Ammonia can damage or etch the surface over time.
  • Dyes and fragrances – The dyes and perfumes in Windex could stain quartz or leave a lingering scent.
  • Streaking – Windex does not contain quartz-safe degreasers. It may leave streaks and residue.
  • Abrasives – If Windex contains gritty abrasives, they could scratch the quartz surface.

Recommended Cleaners for Quartz Countertops

To safely clean quartz countertops without potential for damage, use a cleaner made specifically for quartz and other engineered stones. Here are some good options:

  • Stone cleaner & polishers made for engineered quartz. Look for brands like StoneTech or Granite Gold.
  • Mild dish soap and warm water provide everyday cleaning.
  • For stubborn stains, try an alkaline cleaner made for quartz. Bar Keepers Friend is a good choice.

Avoid glass cleaners, vinegars, lemon or citrus cleaners, abrasive pads, and anything with ammonia. Read all labels carefully.

Cleaning Tips for Quartz Countertops

Follow these tips to safely clean and care for your quartz countertops:

  • Wipe up spills immediately to prevent stains.
  • For everyday cleaning, use mild dish soap and warm water.
  • For a deep clean, use a quartz-specific cleaner.
  • Disinfect with hydrogen peroxide or rubbing alcohol as needed.
  • Avoid abrasive pads or scrub brushes. Use a soft cloth or sponge.
  • Rinse thoroughly after cleaning.
  • Re-seal quartz every 1-2 years with a quartz sealer.

The Bottom Line

Windex Multi-Surface Cleaner is not recommended for quartz countertops. The chemicals and ingredients pose risks of damaging the surface. Instead, use specialty stone cleaners designed specifically for engineered quartz. With the proper gentle cleaning and care, your beautiful quartz countertops will retain their sparkling appearance for many years.

Frequently Asked Questions About Using Windex on Quartz Countertops

Can I use regular Windex on my quartz countertop?

No, regular Windex is not recommended for use on quartz countertops. The ammonia and other chemicals in regular Windex can potentially damage or etch the quartz surface over time. You should only use cleaners specifically formulated for quartz.

What happens if I accidentally used Windex on my quartz?

If you only used Windex once or twice, your countertop is likely fine. However, repeated use of Windex could eventually cause etching or discoloration on the surface. Going forward, switch to using a quartz-safe cleaner. If any damage is visible, consult a countertop professional about potential repair options.

Does Windex Multi-Surface contain ammonia like regular Windex?

Yes, Windex Multi-Surface Cleaner still contains ammonia as one of its active ingredients. Ammonia should always be avoided when cleaning quartz surfaces, so Windex Multi-Surface is not considered safe for quartz.

Can I mix my own DIY quartz cleaner using Windex?

No, you should never mix Windex or ammonia into a homemade quartz cleaner recipe. Use only products specifically designed and labeled as safe for quartz countertops. DIY cleaners may damage the surface.

Will Windex make quartz countertops look streaky and cloudy?

Yes, Windex often leaves unsightly streaks and residue on quartz countertops. It does not contain the proper degreasers and surfactants needed to properly clean quartz without leaving marks. Always use a cleaner made for quartz instead.

Is it okay to use Windex on just part of my quartz countertop?

It’s best to avoid using Windex on any part of your quartz countertop. The chemicals can seep into the surface and cause incremental damage over time. Play it safe and stick to quartz-approved cleaners only.

What’s the worst damage Windex could cause on quartz?

With repeated use, Windex could potentially etch the quartz surface, causing a permanent chemical stain that can only be removed by refinishing the countertop. In worst case scenarios, it could damage the sealant and make the countertop more prone to staining.

What should I do if Windex damaged my quartz countertop?

Stop using Windex immediately. Then inspect the countertop for any signs of etching or discoloration. Light damage may be repairable with an intensive deep cleaning. But if the quartz shows permanent staining or damage, you’ll likely need to hire a professional fabricator to refinish or replace the damaged section.


Quartz countertops provide a beautiful, durable, and low-maintenance surface when properly cared for. It’s important to always use specialized quartz cleaners and avoid products like Windex that contain risky ingredients like ammonia. Following the manufacturer’s care recommendations will keep your quartz countertops in excellent condition for many years. With the right gentle cleaning and maintenance, you can safely enjoy the look and convenience of quartz counters in your home.
