How to Fix Dull Quartz Countertops

Quartz countertops are popular in kitchens and bathrooms for their durability, ease of maintenance, and variety of colors and patterns. However, over time quartz can lose its luster and appear dull. Don’t despair if your once-sparkling quartz countertops look lackluster—with a little effort you can restore their shine. Here are some tips for how to fix dull quartz countertops.

Clean Thoroughly

The first step is a deep clean to remove built-up dirt, grime, soap scum, hard water deposits, and everyday grease and gunk. This will prep the countertops for polishing.

  • Clear the countertops completely—no appliances, decor, etc.
  • Use a degreasing cleaner or mix a solution of warm water and dish soap. Avoid abrasive cleansers.
  • Scrub the entire surface with a soft cloth, sponge, or non-abrasive scrub pad.
  • Rinse thoroughly and pat dry with a soft towel.


Polishing will help smooth away micro-scratches and restore luster.

  • Use a quartz countertop polish specifically formulated for quartz.
  • Apply a dime-sized amount of polish to a soft cloth.
  • Rub the polish over the entire countertop surface using small, circular motions.
  • Buff to a high shine. Use a fresh cloth as needed.
  • Repeat regularly (weekly or monthly) for maintenance.

Remove Etch Marks

Etch marks are light scratches or worn spots etched into the surface. They make quartz look dull and hazy.

  • Try a mild abrasive cleanser like Soft Scrub to rub out very minor etch marks.
  • For deeper marks, use a quartz etching cream. Apply a thin layer, allow to sit for 5 minutes, then scrub.
  • For severe etching, you may need to call in a pro to sand/buff the countertops.


Sealing fills in micro-pores and provides a protective barrier. Resealant can enhance luster.

  • Clean and polish the countertops prior to sealing.
  • Use a sealant made for quartz and apply as directed.
  • Allow to fully cure for 24-72 hours.

Avoid Direct Sunlight

Direct sun exposure can damage and discolor quartz over time. Dullness and etching can occur.

  • Install window treatments to block intense sunlight.
  • Move decor or appliances to prevent harsh sun beating down in one spot.
  • Consider repositioning highly exposed countertops if possible.

With some periodic maintenance and TLC, your quartz countertops can stay looking like new for years before needing professional restoration. Be gentle in your day-to-day cleaning, and avoid using products containing acids, alkaline, or abrasives. Follow these tips to restore and maintain the factory finish shine.
