How to Remove Streaks from Quartz Countertops

Quartz countertops are a popular choice for kitchens and bathrooms due to their durability, stain resistance, and sleek appearance. However, like any surface, quartz can develop unsightly streaks over time from grease, hard water, and daily wear and tear. The good news is that quartz is a non-porous material that can be cleaned and restored to like-new condition with a bit of effort. Here is a comprehensive guide on how to remove streaks from quartz countertops.

What Causes Streaks on Quartz?

There are a few common culprits that can lead to streaking on quartz surfaces:

  • Oils and grease – Cooking oils, lotions, cosmetics, and other greasy substances that come in contact with the countertop can leave behind residue that accumulates into streaks over time.
  • Hard water – Mineral deposits from tap water used for cleaning and cooking can build up on the surface. When the water evaporates, it leaves behind white streaky stains.
  • Soap scum – Soap and shampoo residues can interact with minerals in water and harden into streaky stains.
  • Wear and tear – Over time, the quartz surface can become dulled and develop light scratches that appear streaky under certain lighting.

Supplies Needed to Remove Streaks

Removing streaks from quartz requires using the right cleaning solutions and tools. Here are the recommended supplies:

  • Mild nonabrasive liquid detergent – Look for a grease-cutting formula. Dish soap works well.
  • White vinegar – Helps dissolve soap scum and hard water deposits.
  • Baking soda – Acts as a gentle abrasive to scrub off stains.
  • Soft cloths – Microfiber cloths are ideal for applying cleaners and buffing.
  • Nonabrasive sponge – Choose a soft scrubbing sponge without tough fibers.
  • Razor blade – Useful for scraping off extremely stubborn stains.
  • Rubbing alcohol – Helps sanitize and remove greasy residues.
  • Quartz polish – Restores shine and protects the surface.
