Can Windex be Used on Quartz Countertops?

Quartz countertops are a popular choice for many homeowners due to their durability, aesthetic appeal, and low maintenance. However, like any surface, quartz countertops require proper care and cleaning to keep them looking pristine. A common question that arises is whether Windex is safe to use on quartz. Here is a comprehensive guide on using Windex on quartz countertops.

What is Quartz?

Quartz countertops, also known as engineered stone, are made from crushed quartz crystals combined with resin and other materials. The resulting slabs are non-porous, making quartz more stain-resistant than natural stone. Quartz is also harder than granite, making it very durable. The resin binding minimizes pores, cracks and natural stone variations. This makes quartz an ideal low maintenance surface.

Is Windex Safe for Quartz?

Windex is generally considered safe for cleaning quartz countertops. The active ingredients in Windex are ammonia, isopropanol, and ethylene glycol. When used properly, these ingredients will not etch or damage a quartz surface.

However, there are a few precautions to take when using Windex on quartz:

  • Avoid abrasive Windex versions that contain vinegar or other acidic ingredients, as these can dull the surface over time. Stick to regular, non-abrasive Windex.
  • Use a soft, non-abrasive cloth when applying Windex to prevent microscopic scratches. Paper towels are too rough for quartz.
  • Rinse thoroughly after cleaning because Windex can leave a sticky, cloudy residue on the countertop if left to dry.
  • Spot test Windex on an inconspicuous part of the quartz to check for any adverse reactions.

How to Use Windex on Quartz Countertops

Here are some tips for safely using Windex to clean quartz countertops:

1. Dust and Wipe the Surface

Wipe down the countertop with a soft, dry microfiber cloth first to remove any loose dust or debris. This prevents that gritty dust from scratching the surface when wiped with a wet cloth.

2. Mix the Cleaning Solution

Mix a ratio of 1 part Windex to 3 parts water in a spray bottle. Diluting it reduces the concentration of chemicals. This homemade quartz cleaner is safe yet effective.

3. Spray and Wipe

Lightly spray the diluted Windex directly onto your microfiber cloth. Never spray directly onto the quartz.
Wipe down the counters in circular motions until the surface is spotless. Apply light pressure, especially on stubborn spots.

4. Rinse and Dry

Use a clean damp microfiber cloth to wipe off any Windex residue. Follow with a dry cloth to fully dry the surface. Any moisture left behind can damage quartz over time.

5. Reseal and Polish Quarterly

Reapply a quartz sealer and use a quartz polish every 3-4 months to maintain the protective layers on your countertops. This prevents etching and keeps surfaces smooth.

What to Avoid When Cleaning Quartz

While Windex is generally safe for cleaning quartz, avoid:

  • Vinegar, lemon, or any acidic cleaners – will etch the surface. Stick to pH neutral cleaners.
  • Abrasive powders, scouring pads, and scrub brushes – can create micro-scratches.
  • Letting spills sit – clean up promptly to avoid stains setting.
  • Using too much pressure when wiping the surface.
  • Damp or wet countertops for prolonged periods.

How to Remove Windex Residue from Quartz

If Windex dries and leaves a cloudy, sticky film behind, there are a few remedies:

  • Mix equal parts warm water and isopropyl alcohol and wipe down the surface. This will cut through the residue.
  • Make a paste of baking soda and water. Gently scrub with a soft cloth then rinse.
  • Use a quartz polish to remove residue and enhance shine.
  • For tough residue, apply a quartz cleaner and let sit for 5 minutes before scrubbing and rinsing.

Quartz Countertop Maintenance

To keep your quartz counters looking like new:

  • Clean spills quickly to prevent staining, especially oils, wine and fruits.
  • Regularly disinfect surfaces with an antimicrobial quartz cleaner.
  • Avoid placing hot pots/pans directly on quartz. Use trivets.
  • Reseal quartz every 6 months – 1 year based on usage.
  • Use a quartz polish monthly to clean and enhance shine.
  • Have countertops professionally cleaned and resealed annually.


Windex is generally considered safe for cleaning quartz countertops as long as you follow the proper procedures. Always dilute it, rinse thoroughly, use a soft cloth, and avoid acidic formulations to prevent damaging the quartz. With the right gentle cleaning methods, Windex can keep quartz counters looking beautiful and sanitized. Be sure to reseal and polish regularly as well. Follow these tips, and you can safely use Windex to maintain gorgeous, sparkling quartz countertops.

Frequently Asked Questions

Here are some common questions about using Windex on quartz countertops:

Can I use Windex daily on my quartz countertops?

It’s best to not use Windex daily, but instead clean quartz regularly with a pH neutral quartz cleaner. Use Windex sparingly 1-2 times a week at most. Frequent use can strip off the protective sealant over time.

What ratio of water to Windex should be used?

Mix a solution of 1 part Windex to 3 parts water. This dilutes the cleaner to make it gentler on the quartz surface while still effective. Never use full-strength Windex.

Can vinegar be mixed with Windex to clean quartz?

No, never mix vinegar with Windex. Vinegar is too acidic for quartz and can dull the surface. Use only non-abrasive, regular Windex diluted with water.

Should Windex be rinsed off quartz?

Yes, always rinse the countertops thoroughly after cleaning with Windex. It can leave a cloudy, sticky residue if left to dry on the surface. Wipe off with water and dry completely.

How can I remove hard water marks from my quartz countertops?

For hard water stains, use a mix of equal parts white vinegar and water. Let it sit for 5 minutes before scrubbing and rinsing well. This can help dissolve mineral deposits. Avoid vinegar otherwise.

Can I use Windex on polished quartz?

Yes, diluted Windex may be used on polished quartz. But be extra careful to use only a soft cloth when wiping to prevent micro-scratches on the polished finish. Avoid abrasive pressure.

What happens if Windex etches my quartz countertop?

If improper cleaning causes Windex to etch your quartz, the dull spots can be professionally refinished and re-polished. Prevent this by always diluting Windex and rinsing thoroughly after use.
