Can You Use Windex To Clean Quartz Countertops?


Quartz countertops are an increasingly popular option for kitchen and bathroom remodels thanks to their durability, low maintenance, and stylish appearance. However, like any surface, quartz countertops require proper cleaning and care to keep them looking pristine. Some homeowners wonder if using Windex is safe for cleaning quartz. Below, we’ll explore whether Windex can be used on quartz and provide tips for keeping quartz surfaces sparkling clean.

Is Windex Safe for Quartz Countertops?

The short answer is yes, Windex is generally considered safe for cleaning quartz countertops. Windex is a mild cleaner made of ammonia, water, fragrances, and dye. Quartz is non-porous, so harsh chemicals like ammonia don’t penetrate or damage the surface.

However, Windex isn’t necessarily the best or most effective option for routine quartz countertop cleaning. Quartz manufacturers recommend pH-balanced stone cleaners specifically formulated for quartz. While Windex may be used in a pinch, it’s best to rely primarily on specialized quartz cleaners.

Using Windex on Quartz Countertops

If you need to use Windex on your quartz, follow these tips:

  • Test Windex on a small, inconspicuous area first to check for any adverse effects.
  • Use a soft microfiber cloth rather than paper towels, which can scratch quartz.
  • Avoid using acidic cleaners like Windex daily, as acids can dull quartz over time.
  • Rinse thoroughly after cleaning and dry with a soft cloth to prevent streaks.
  • Mix Windex with water at a 1:1 ratio to dilute it before applying to quartz.
  • Opt for Windex formulas without dyes or fragrances, which can leave residue.
  • Don’t use Windex on countertops if it contains ammonia-free formulas, which are less effective.

Best Practices for Cleaning Quartz Countertops

For routine cleaning, use a pH-balanced quartz countertop cleaner and soft cloth. Quartz specific cleaners contain mild detergents to lift dirt and grime without stripping away the surface shine.

Here are some top tips for keeping quartz spotless:

  • Everyday Cleaning: Use a damp microfiber cloth with a small amount of quartz cleaner. Avoid abrasive pads or brushes.
  • Deep Cleaning: Apply a quartz-safe degreaser like diluted dish soap and rinse thoroughly.
  • Disinfecting: Opt for hydrogen peroxide, rubbing alcohol, or vinegar as safer options over harsh bleach.
  • Polishing: Restore shine every couple months with a quartz polish formulated for stone surfaces.
  • Preventing Damage: Always use cutting boards and trivets to protect from scratches and heat.
  • Avoiding Stains: Rinse spills immediately before they set into the surface texture. Dry with a soft cloth.

FAQ About Using Windex on Quartz

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

No, you should avoid using Windex as your daily quartz cleaner. The acids and chemicals in Windex can damage and dull the countertop over time with daily use. Opt for a specialized stone cleaner instead.

What happens if I accidentally get Windex on my quartz?

If you inadvertently get Windex on your quartz, immediately rinse it off with water and dry the surface with a soft cloth. Ensure no Windex residue remains. This should prevent any damage to your quartz.

Can I mix Windex with water to make it safer for quartz?

Yes, you can dilute Windex with an equal part water. This creates a gentler cleaning solution less likely to harm quartz with prolonged use. Make sure to rinse thoroughly after cleaning.

Does using Windex on quartz void the manufacturer warranty?

It’s unlikely using Windex occasionally would void the warranty, but check your warranty specifics to be sure. Prolonged Windex use may dull quartz over time, potentially impacting warranty coverage.

What’s the best quartz countertop cleaner brand to use instead of Windex?

Popular quartz cleaner brands include Granite Gold, Black Diamond, and StoneTech. Always check the label to confirm the cleaner is formulated for quartz rather than natural stone.


While Windex can be used in a pinch, it’s best to stick to specialized quartz cleaners for routine maintenance. Windex contains chemicals and fragrances that may leave residue or damage quartz over time. With proper daily and weekly cleaning using the right quartz products, you can keep your countertops looking like new for years to come. Be sure to rinse thoroughly when using any cleaning products and follow quartz manufacturer care recommendations. With just a little care, your beautiful quartz countertops will maintain their elegant, durable shine.
