Can I Use Windex on Quartz Countertops?

Quartz countertops are a popular choice for many homeowners due to their durability, aesthetics, and low maintenance. However, it’s important to clean quartz properly to keep it looking its best. A common question that arises is whether or not Windex is safe to use on quartz. Here is a detailed look at using Windex on quartz countertops.

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 resistant to scratches, stains, heat, and water.

Some key properties of quartz:

  • Extremely durable and long-lasting
  • Available in a wide range of colors and patterns
  • Non-porous so resists staining
  • Heat and scratch resistant
  • Easy to clean and maintain
  • Does not require sealing

Quartz provides an attractive, low-maintenance surface perfect for busy kitchens.

Is Windex Safe for Cleaning Quartz?

Windex is a popular household cleaner made by S.C. Johnson & Son. The original formula contains ammonia-D, water, fragrance, and dye.

The short answer is yes, Windex is generally considered safe to use on quartz countertops. However, there are a few caveats to keep in mind:

  • Use Windex as directed – diluted and in small amounts. Never use undiluted or in large quantities.
  • Spot test a small inconspicuous area first to check for any adverse effects.
  • Windex Original contains ammonia which can damage some quartz over time with repeated use. Consider Windex Vinegar or Windex Multi-Surface which are ammonia-free.
  • Avoid using on quartz with a polished or glossy finish, as it can dull the surface over time.
  • For regular cleaning, a mild soap and water is best for quartz. Use Windex only occasionally for stubborn spots.

The key is to never use Windex excessively or let it sit or soak on the quartz. When used properly and in moderation, it can be used to safely clean quartz countertops.

Best Practices for Using Windex on Quartz

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

  • Spot test first on a small inconspicuous area to check for any damage or change to the finish.
  • Use only as needed for periodic or spot cleaning. For routine cleaning, use a mild pH-neutral cleaner.
  • Use a soft microfiber cloth and spray Windex directly onto the cloth. Never directly spray the countertop.
  • Use only a small amount of Windex – don’t saturate the surface.
  • Rinse thoroughly with clean water and dry with a soft cloth after cleaning.
  • Opt for Windex Vinegar or Windex Multi-Surface as they do not contain harsh ammonia.
  • Avoid using on polished, glossy, or delicate quartz finishes.
  • Never use undiluted or allow Windex to soak into the quartz.

Taking these precautions will allow you to safely use Windex on quartz surfaces when needed.

Quartz Cleaning and Care Tips

To keep your quartz countertops looking like new, follow these care and cleaning guidelines:

  • For daily cleaning, use a soft sponge or cloth with warm water and mild pH-neutral soap or cleaner.
  • Rinse well and dry with a soft cloth to prevent water spots.
  • For stubborn stains, use a non-abrasive cleaning pad with a small amount of glass cleaner, hydrogen peroxide, or ammonia-free Windex.
  • Avoid abrasive cleaners, scouring pads, or anything acidic like vinegar or lemon juice. This can etch or dull the surface.
  • Blot spills quickly to prevent stains – quartz is non-porous but prolonged exposure can cause discoloration.
  • Reseal quartz annually with a stone sealer formulated for quartz.
  • Avoid placing hot pots/pans directly on the surface. Use trivets and hot pads.
  • Don’t use quartz as a cutting surface. Always use a cutting board.
  • Clean up spills from oils, wines, tomatoes, and other staining foods promptly.

FAQs about Using Windex on Quartz

Is it okay to use Windex every day on my quartz countertops?

No, you should not use Windex as your daily cleaner for quartz countertops. The ammonia and other chemicals can damage the finish over time with daily use. For routine cleaning, stick to a mild soap and water instead. Save the Windex for periodic spot cleaning.

What’s the best Windex variety for quartz?

Opt for Windex varieties that don’t contain ammonia, like Windex Vinegar or Windex Multi-Surface cleaner. These are gentler for regular use on quartz than original Windex with ammonia.

Can I rub a quartz countertop with Windex and a paper towel?

It’s best to spray Windex directly onto a soft cloth first rather than the countertop. Rubbing the surface aggressively with a paper towel can potentially cause light scratches over time. Use a gentle circular motion with a damp microfiber cloth instead.

Is it okay to use Windex on polished or glossy quartz?

No, avoid using Windex on polished, glossy, or delicate quartz finishes as it can dull the shine over time. For those quartz surfaces, stick to mild pH-neutral cleaners.

What happens if Windex sits on quartz for awhile?

It’s best to wipe up Windex immediately and not allow it to pool or soak into the surface. Given it contains ammonia, a lengthy exposure time can potentially etch or discolor quartz. Long-term wet exposure should always be avoided.


While Windex is not recommended as an everyday cleaner for quartz countertops, it can occasionally be used safely if proper precautions are followed. Always spot test first, never allow it to soak, use only a small amount with a soft cloth, and rinse thoroughly after cleaning. For routine cleaning and care, mild soapy water is best to maintain the beauty of quartz surfaces. Being careful about using the proper quartz-safe cleaning methods will keep your countertops looking pristine for years to come.
