How to Get Rid of Dull Spots on Quartz Countertops

Quartz countertops are popular options for many homeowners due to their durability, aesthetics, and low maintenance. However, even quartz can develop dull, stained, or etched spots over time with daily use. Here are some tips on how to get rid of dull spots on quartz countertops and restore their original luster.

Cleaning Products to Use on Quartz Countertops

When trying to remove dull spots from quartz, it’s important to use the right cleaning products that are safe for this material. Here are some good options:

  • Mild dish soap and warm water – Great for general surface cleaning. Avoid dish soaps with added cleaners like bleach.
  • Stone soap or mild alkaline cleaner – Specialty soaps designed for natural stone can help dissolve soils. Look for a pH of 10-11.
  • Baking soda – A gentle abrasive that can help remove some etched spots when made into a paste.
  • Hydrogen peroxide – Helps lift stains and is safe for quartz. Combine with baking soda for extra cleaning power.
  • Scotch-Brite pad – For gently scrubbing dried spills or gunk. Use a soft sponge otherwise to avoid scratching.

Cleaners to Avoid

Stay away from the following products on quartz:

  • Vinegar, lemon juice, or other acids – Will etch and corrode quartz.
  • Abrasive scrubbers – Can leave fine scratches on the surface over time.
  • Bleach-based cleaners – Too harsh and may discolor quartz.
  • Lacquer thinner, paint remover – Will damage the resin coatings.
  • Products with oils/waxes – Can leave residue buildup and attract dirt.

Steps to Remove Dull Spots from Quartz

Follow these steps to effectively remove dull spots from your quartz countertops:

1. Prepare the Surface

Clear everything off the countertop. Dull spots will be easier to identify and target if the surface is empty.

2. Inspect and Identify the Spots

Examine the countertop closely. Determine if the dull spots are stains, etched marks from acids, buildup of grime or residue, etc. This will help guide the best treatment.

3. Try General Cleaning First

First attempt to remove any dull spots using a mild dish soap, warm water, and soft scrubbing with a sponge or rag. This may take care of basic dirt and grime.

4. Use Baking Soda for Stubborn Spots

For spots that don’t come out with basic cleaning, make a paste of baking soda and water. Apply the paste to problem areas and let sit for 5-10 minutes before scrubbing and rinsing. Baking soda provides gentle abrasion to lift some stains.

5. Use Household Products for Certain Spots

Here are some spot treatments:

  • Oil/grease stains – Dab on hydrogen peroxide and allow to fizz for 2-3 minutes before rinsing.
  • Hard water spots – Make a paste with baking soda and vinegar. Scrub and then rinse thoroughly.
  • Dried spills – Pour boiling water directly on the spot to help loosen. Then scrub with a Scotch-Brite pad.

6. Try a Specialty Stone Cleaner

For persistent dull spots or mineral etching, use a specially formulated stone cleaner. Apply to the countertop and let soak for 5-10 minutes before scrubbing and rinsing. May require repeated applications.

7. Call for Professional Help

For severe dullness issues that won’t respond to home treatments, contact a professional stone restoration company. They have commercial grade equipment and chemicals to re-polish quartz. Expect to pay $100-200 minimum.

Prevention Tips to Keep Quartz Gleaming

Once you’ve succeeded in removing dull spots from your quartz, keep the surface looking its best by:

  • Using cutting boards and trivets to protect from knives and hot pans.
  • Immediately wiping up spills, especially acidic substances like wine, juice and vinegar.
  • Avoiding abrasive cleansers and scrub pads which can lead to swirl marks.
  • Cleaning quartz 1-2 times per week with a soft sponge or microfiber cloth.
  • Applying a stone sealer every 1-2 years for added protection.

With some elbow grease and the right cleaning techniques, you can banish dull spots from quartz. Follow these steps to restore the original radiant finish. Be sure to properly care for quartz daily to prevent recurring dullness issues. Your counters will look like new for many years to come with regular cleaning and maintenance.

Frequently Asked Questions About Removing Dull Spots from Quartz Countertops

What causes dull spots on quartz?

Some common causes of dull spots on quartz include:

  • Etching from acidic substances like citrus, vinegar, wine
  • Stubborn dried-on spills or splatters
  • Hard water spotting from minerals in tap water
  • Accumulation of dirt, oil and greasy residues
  • Bacteria growth in small scratches or grooves
  • Discoloration or clouding from direct sun exposure
  • Normal wear-and-tear over time without proper cleaning

Can I use a magic eraser on quartz countertops?

Magic erasers can technically be used on quartz but should be done very gently and infrequently. The melamine foam material is a mild abrasive, so excessive scrubbing can lead to hazy scratches on quartz over time. Limit magic eraser use to occasional spot cleaning.

How can I make my dull quartz countertops shine again?

To make dull quartz countertops shine again, use a combination of baking soda and water paste, specialty stone cleaners, hydrogen peroxide, and a soft buffing pad to gently clean and restore the surface luster. For severe dullness, contact a professional for re-polishing services using commercial diamond pads and compounds.

Will sealing help keep my quartz countertops looking new?

Sealing is an optional step that can help prolong the like-new shine of quartz counters. A stone sealer fills in microscopic pores to prevent dirt buildup and staining. Re-apply sealer every 1-2 years. But sealing won’t prevent etching or other wear-and-tear over time. Proper daily maintenance is still needed.

Can I use a steam cleaner on quartz countertops?

Steam cleaners are not recommended for use on quartz. The intense heat and pressure generated by steam cleaners can potentially damage the resin binders in quartz. Stick to mild alkaline cleaners and hand scrubbing to safely clean quartz without risk of harm.


Dull spots on quartz countertops are common but can be removed with some determination and the right techniques. Always test any cleaning product on a small inconspicuous area first to ensure it won’t damage the quartz. Consistent maintenance cleaning combined with early treatment of any dulled areas will keep your quartz counters gleaming for years. With quartz becoming such a popular countertop material, it’s important for homeowners to learn proper care and cleaning methods to preserve the look and longevity.
