Can I Clean Quartz Countertops with Windex?

Quartz countertops are popular in many homes due to their durability, stain resistance, and low maintenance. However, even quartz needs regular cleaning to keep it looking its best. Some homeowners wonder if using Windex is safe for cleaning quartz countertops. Here is what you need to know about using Windex on quartz countertops.

An Overview of Quartz Countertops

Quartz countertops, often referred to as engineered stone, are made from ground quartz crystals combined with resins and pigments. The result is a hard, non-porous surface that is resistant to scratches, stains, and heat.

Some key advantages of quartz countertops include:

  • Durable – Quartz is harder and less prone to chipping than natural stone.
  • Low Maintenance – Quartz resists stains and requires very little sealing.
  • Non-Porous – Liquids don’t soak into quartz so it won’t harbor bacteria.
  • Variety of Colors/Patterns – Quartz comes in many color and pattern options to suit any decor.
  • Heat Resistant – Quartz can withstand heat better than solid surface counters.

However, quartz can be damaged by strong chemicals, so care must be taken when cleaning.

Is Windex Safe for Cleaning Quartz?

Windex is a popular household glass and surface cleaner that contains ammonia. Many homeowners use it for quick daily cleaning tasks throughout the home. But is it safe to use on quartz countertops?

The short answer is yes, Windex is generally considered safe for cleaning quartz counters. However, there are a few caveats to keep in mind:

  • Use it sparingly – While ammonia-based cleaners are okay for occasional use on quartz, you don’t want to over-use them. Too much exposure over time may dull the finish.
  • Stick to a mild formula – Opt for Windex Original over stronger specialty formulas like Windex Vinegar or Windex Multi-Surface. The original blue Windex has a mild ammonia formula that is quartz-friendly.
  • Spot test first – Before using Windex on your whole quartz counter, spritz a small inconspicuous area and wipe clean to test for any reaction.
  • Rinse thoroughly – After cleaning with Windex, rinse the counter well with clean water to remove any cleaner residue.
  • Limit use to countertops – Only use Windex on quartz counter surfaces. Avoid using it on other quartz surfaces like shower walls or backsplashes.
  • Use a soft cloth – Always use a soft, non-abrasive cloth when cleaning quartz. Paper towels or microfiber cloths are ideal.

Best Practices for Cleaning Quartz Countertops

While Windex is okay for occasional use, you’ll want to follow these best practices for regular quartz cleaning and care:

1. Daily Cleaning

For daily cleaning, warm water and a few drops of mild dish soap are all you need. Wipe down surfaces with soapy water using a soft cloth or sponge. Rinse well and dry with a clean towel.

2. Dried Spills and Stains

For stuck-on messes like dried food spills, grease, and stubborn stains, use a non-abrasive cleaning pad such as a white Scotch-Brite pad with warm soapy water. Apply some elbow grease to gently scrub the mess away. Avoid using abrasive scouring pads or powders that could scratch the finish.

3. Disinfecting Cleaning

To safely disinfect your quartz countertops, look for an EPA-registered disinfectant made specifically for use on quartz surfaces. Many popular brands like Clorox and Lysol make quartz-safe disinfecting wipes and cleaners.

4. Avoid Certain Cleaners

Steer clear of the following types of cleaners on quartz:

  • Vinegar or lemon juice – Acids can dull the finish
  • Concentrated bleach – May cause discoloration
  • Harsh chemicals like oven cleaner, drain cleaner, etc.
  • Abrasive powders or scouring pads

5. Preventing Damage

Simple habits like using cutting boards and trivets can help prevent scratching, etching, or chipping on your quartz counters. Immediately wipe up any spills, especially acidic substances like wine or fruit juice.

When to Call a Professional

For issues like tough stains that won’t budge, or a hazy finish that needs polishing, it’s best to call in a professional quartz countertop cleaning company. They have specialized tools and training to safely deep clean and restore the finish on quartz counters without causing harm.


Overall, Windex is considered a quartz-safe cleaner when used properly and in moderation. The mild ammonia formula won’t damage or etching quartz surfaces with occasional use. However, for regular cleaning and disinfecting it’s better to stick to pH-neutral soapy water or commercial quartz cleaners. With the right products and cleaning methods, quartz countertops can stay looking like new for many years. Be sure to spot test Windex first and rinse thoroughly after use. And take care to avoid harsh chemicals or abrasive pads that could damage the surface. With some basic care and caution, Windex can be used to safely clean quartz counters when needed.

Can I Clean Quartz Countertops with Windex?

Cleaning quartz countertops regularly is important to maintain their beauty and function. Some homeowners wonder if commercial glass cleaners like Windex are safe to use on quartz. Here’s a detailed look at the facts.

What is Quartz?

Quartz countertops, often called engineered stone counters, are made from ground quartz crystals combined with resins, pigments, and other compounds. Quartz is an extremely hard material that produces a durable non-porous surface.

Key features:

  • Resists scratches, stains, heat, and moisture
  • Wide variety of colors and patterns
  • Low maintenance
  • More affordable than natural stone
  • Resists bacteria growth

However, quartz can be damaged by harsh chemicals or cleaners.

Is Windex Safe for Quartz?

Windex is a popular household cleaner used on windows, mirrors, and other surfaces. The standard blue Windex contains ammonia, which helps cut through grease and grime.

But is it safe to use on quartz countertops?

The short answer is** yes, Windex is generally considered quartz-safe** when used properly. Most countertop manufacturers approve using Windex or similar ammonia-based cleaners in moderation.

However, there are guidelines to follow:

  • Use mild original Windex, not stronger specialty formulas
  • Use sparingly, not as an everyday cleaner
  • Spot test on a small area first
  • Thoroughly rinse counters after use
  • Only use on counter surfaces, not walls or backsplashes

Harsh chemicals like Windex should also be avoided on certain quartz varieties more prone to etching. When in doubt, check with your countertop manufacturer.

Best Practices for Cleaning Quartz

For routine cleaning, soap and water are best for quartz. Follow these top tips:

  • Daily cleaning – Warm water and mild dish soap

Frequently Asked Questions

Can I use Windex daily on my quartz countertops?

No, you should not use Windex daily on quartz counters. The ammonia in Windex could eventually dull the finish if overused. Limit Windex to occasional targeted cleaning for best results.

What happens if Windex sits on quartz?

If Windex residue is left to sit on quartz, it could lead to buildup that leaves streaks and affects the finish over time. Always rinse counters thoroughly after using Windex.

Can I mix Windex and water to clean quartz?

It’s best not to dilute or mix Windex with water for cleaning quartz. Using the Windex formula as-is will allow it to effectively cut through grease. Be sure to rinse well after cleaning.

Will Windex etching my quartz countertops?

On most standard quartz varieties, occasional Windex use will not etch or damage the surface. However, some sensitive quartz types are more prone to etching from chemicals. Do a small test first to ensure the Windex does not affect your specific quartz material.

What happens if I get Windex on my quartz backsplash?

Since quartz backsplashes are more prone to etching damage, it’s best to avoid using Windex or any harsh chemicals on these vertical surfaces. Stick to gentle soap and water instead.
