Can I Use Windex on My Quartz Countertops?

Quartz countertops are a popular choice for many homeowners due to their durability, appearance, and low maintenance. However, it’s important to clean quartz properly to keep it looking its best. Using the wrong cleaning products can damage the surface over time. So, can you use Windex on quartz countertops?

What is Quartz?

Quartz countertops, sometimes called engineered stone, are made from ground natural quartz crystals combined with polyresin and pigments. The result is a non-porous, durable surface that resists scratches, stains, and heat better than natural stone.

Some key features of quartz countertops:

  • Extremely durable and long-lasting
  • Resists stains, scratches, and heat
  • Non-porous so doesn’t require sealing
  • Available in a wide variety of colors and patterns
  • Requires very little maintenance

Is Windex Safe for Quartz?

Windex is a popular household cleaner made by S.C. Johnson. The original formula contains ammonia, which can potentially damage some surfaces. However, Windex now makes specialized cleaners approved for use on quartz:

  • Windex Glass and Surface Vinegar Cleaner – Formulated with vinegar instead of ammonia, safe for quartz.
  • Windex Granite and Stone Cleaner – Specifically designed for natural stone and engineered surfaces like quartz.

As long as you choose a quartz-safe Windex variety without ammonia, it can be used to clean quartz safely and effectively.

Best Practices for Cleaning Quartz Countertops

While quartz is very low maintenance compared to other countertop materials, proper care is still required to keep it looking pristine. Here are some tips:

  • For daily cleaning, use a soft sponge or microfiber cloth with warm water and mild soap. Avoid abrasive cleaners or pads.
  • For a deeper clean, use a specially formulated quartz cleaner like Windex Vinegar or Granite & Stone cleaner.
  • Disinfect quartz periodically with diluted white vinegar or rubbing alcohol.
  • Avoid cleaners containing lemon, vinegar or other acids. They can dull the surface.
  • Rinse thoroughly after cleaning and dry with a soft cloth to prevent water spots.
  • Reseal quartz every 1-2 years with a specialty sealer made for engineered stone.
  • Immediately wipe up spills, especially oils, wines and other staining agents.
  • Avoid exposing quartz to excessive heat. Always use trivets for hot pans.
