Can You Clean Quartz Countertops With Windex?

Quartz countertops are an increasingly popular choice for kitchen and bathroom surfaces due to their durability, aesthetics, and low maintenance. However, like any surface, quartz countertops require proper cleaning and care to keep them looking their best. A common question that arises is whether or not quartz can be cleaned with Windex or other glass cleaners. Here is a detailed look at using Windex on quartz.

An Introduction to Quartz Countertops

Quartz countertops, often referred to as engineered stone, are made from ground quartz crystals combined with resins and pigments. The resulting material is non-porous, making it resistant to stains, scratches, and heat. Quartz is an ideal choice for busy kitchens and bathrooms because it is:

  • Durable – Quartz is resistant to chipping, scratches, and cracks. It can withstand heat up to 212°F.
  • Low Maintenance – Quartz resists staining and requires very little sealing or conditioning.
  • Stylish – Quartz comes in a wide variety of colors and patterns to suit any décor.

However, quartz still requires proper care and cleaning to maintain its beauty. Let’s look at whether Windex can be used safely.

Can Windex Be Used on Quartz?

Windex is a popular glass and surface cleaner found in many homes. It typically contains ammonia, which helps cut through grease and grime on hard surfaces. However, Windex and similar glass cleaners are not recommended for use on quartz countertops. Here’s why:

1. Potential for Damage

The ammonia in Windex can potentially dull the quartz surface and damage the resin binders that give quartz its strength and structure. Over time, frequent Windex use could lead to etching, discoloration or loss of shine.

2. Streaking or Filming

Quartz is less porous than natural stone. Using Windex can leave behind streaks of ammonia residue. This filmy residue is hard to remove from quartz compared to glass or tile surfaces.

3.Manufacturer Recommendations

Most major quartz manufacturers like Caesarstone, Cambria, and Silestone do not recommend using Windex or any cleaner with ammonia. It violates most warranty policies.

For these reasons, it’s best to avoid glass cleaners and instead use specially formulated stone and quartz cleaners.

Recommended Cleaners for Quartz Countertops

To safely clean and care for your quartz surfaces, use these recommended products instead of Windex:

  • Mild soap and water – For routine cleaning, use a soft sponge or cloth with warm water and mild soap. Avoid abrasive scrubbing.
  • Stone-specific cleaners – Look for cleaners labeled for use on quartz, engineered, or natural stone. Popular brands include Method Daily Granite, Weiman Stone Cleaner, and Granite Gold Daily Cleaner.
  • Hydrogen peroxide – As a weekly cleaner, use a soft cloth with hydrogen peroxide to help kill bacteria and remove stains.
  • Baking soda – Make a paste with baking soda and water to gently clean and polish the surface. Rinse thoroughly after.

Always refer to your specific quartz manufacturer’s care guidelines for approved cleaning products. Avoid acidic or abrasive cleaners. With proper maintenance, your quartz countertops will stay beautiful for years.

FAQ About Cleaning Quartz Countertops

Still have some questions about keeping your quartz sparkling clean? Here are answers to some frequently asked questions:

Can I use vinegar to clean quartz?

No, vinegar is too acidic for quartz and can dull the surface. Stick to mild pH-neutral cleaners.

How do I sanitize quartz countertops?

Use a sanitizing spray or wipe containing chlorine bleach. Avoid excessive rubbing.

What removes dried spills or stuck-on gunk?

For dried messes, let a damp cloth soaked in warm, soapy water sit on the spot for several minutes to soften. Then gently scrub with a soft brush or sponge. Avoid harsh scrubbing.

How often should I seal quartz counters?

Quartz does not require frequent sealing like natural stone. Once a year is sufficient, using a stone sealer approved for quartz.

Can I use Mr. Clean or other multi-surface cleaners?

Avoid all-purpose cleaners, since they may contain ammonia, acids, or abrasives. Stick to cleaners specifically formulated for stone surfaces.

What about cleaning quartz countertops with bleach?

Undiluted bleach can damage or discolor quartz. Look for cleaners containing diluted chlorine bleach designed for stone and quartz.


Quartz countertops offer gorgeous, low-maintenance surfaces, but do require gentle cleaning suited to the material. Avoid glass cleaners like Windex or anything with ammonia. Instead, clean quartz with mild soap and water, stone-specific cleaners, or diluted hydrogen peroxide. With proper care, your quartz counters will stay looking like new for years to come. Follow manufacturer guidelines and use only approved products. Avoid abrasive cleaners or pads. Treated properly, quartz countertops are an excellent choice that can handle the wear and tear of busy kitchens.
