How to Remove Limescale from Quartz Countertops

Limescale buildup on quartz countertops can be unsightly and difficult to remove. However, with the right techniques and products, you can restore the pristine look of your quartz. Here is a comprehensive guide on how to effectively remove limescale from quartz countertops.

What Causes Limescale on Quartz?

Limescale, also known as hard water deposits, form when minerals like calcium and magnesium in hard water evaporate and leave behind a chalky residue.

Factors that can lead to limescale buildup on quartz countertops include:

  • Living in an area with hard water
  • Allowing water to pool and evaporate on the countertop
  • Not wiping up spills quickly
  • Using soaps and cleaners that leave residue

Over time, the limescale deposits build up and become difficult to remove.

Can Limescale Damage Quartz?

Limescale itself does not damage quartz since quartz is non-porous. However, trying to scrub off stubborn limescale stains can potentially damage the surface over time.

Using harsh chemicals and abrasive pads to remove the stains can dull and etch the quartz finish. So it’s important to use the right limescale removal methods that are safe for your countertops.

Best Ways to Remove Limescale from Quartz

Here are the most effective methods and products for safely removing limescale from quartz:

1. White Vinegar

White vinegar is a mild acid that helps dissolve limescale deposits.


  • Mix equal parts white vinegar and warm water.
  • Use a soft cloth to apply the solution to the limescale stains.
  • Let it sit for 5-10 minutes to allow the vinegar to work.
  • Wipe off with a clean damp cloth and dry thoroughly.

Repeat as needed until the stains are gone.

2. Citric Acid

Citric acid powder is another effective way to dissolve and remove limescale.


  • Mix 2-3 tablespoons of citric acid with 1 cup of warm water.
  • Apply the solution to the stains with a soft cloth.
  • Let sit for 5 minutes before wiping clean with water.

For tougher stains, leave the solution on for 10-15 minutes before rinsing.

3. Baking Soda Paste

Baking soda works as a gentle abrasive to scrub off limescale deposits.


  • Make a paste with 3 parts baking soda and 1 part water.
  • Apply the paste to the stains and let sit for a few minutes.
  • Gently scrub with a soft cloth or sponge.
  • Rinse thoroughly and dry.

4. Limescale Remover Products

Look for commercial limescale removers made specifically for use on quartz and natural stone. These are gentler than many household cleaners.


  • Apply the limescale remover as directed on the product label.
  • Let it sit for the recommended time.
  • Scrub gently with a soft brush or sponge.
  • Rinse thoroughly.

Popular picks include Bartlett Pro-Stone & Quartz Cleaner and GranQuartz Melt Away. Always spot test first.

Tips for Preventing Limescale Buildup

To minimize limescale from recurring frequently:

  • Wipe up water and spills right away. Don’t let moisture sit.
  • Use coasters under glasses and bottles.
  • Consider installing a water softener system if you have very hard water.
  • Use cleaners formulated for stone to avoid residue buildup.
  • Apply a quartz sealer every 1-2 years for added protection.

Can You Remove Limescale Yourself or Call a Professional?

For light limescale stains, DIY removal using the methods above often works well.

However, for heavy calcification that has built up over many years, consider calling in a professional stone restoration company. They have access to more powerful limescale removal solutions that can tackle the toughest hard water stains without damaging the quartz.

Professionals also have specialized tools like rotary polishers that can resurface and restore the quartz to a like-new finish after deep cleaning.

While DIY limescale removal is cost-effective for minor stains, professionals may be worth the investment for countertops with excessive etching and buildup.
