How to Surface Polish Quartz Countertops

Quartz countertops are a popular choice for kitchens and bathrooms due to their durability, aesthetics, and low maintenance. However, over time quartz can develop minor scratches, etching, and lose its luster. With proper techniques and products, you can restore the surface polish to make quartz look brand new again. Here is a step-by-step guide on how to surface polish quartz countertops.

What You’ll Need


  • Quartz polish or sealant
  • Microfiber cloths
  • Soft buffing pad or applicator
  • Kitchen scrub pad
  • Mild detergent


  • Variable speed polisher/buffer (optional)


  • Rubber gloves
  • Safety goggles
  • Dust mask

Step 1 – Clean the Surface

Before polishing, thoroughly clean the quartz surface to remove any dirt, grime, or waxes which can interfere with the polishing process.

  • Wash the countertop with a mild detergent and warm water using a soft scrub pad. This helps eliminate any oils or greasy residues.
  • Rinse well and use a microfiber cloth to wipe away any soap or water spots.
  • Allow the surface to fully dry. Pay special attention to drying any seams or edges.

Step 2 – Inspect for Etching or Damage

Closely inspect the quartz to determine the severity of any dullness or damage:

  • Minor dullness/fading: Characterized by loss of shine but no noticeable etching or pits. Can be restored with polishing.
  • Light to moderate etching: Visible scratched or pitted areas. May require spot treatment prior to polishing.
  • Heavy etching/damage: Deep scratches, gouges and eroded areas. May require professional resurfacing if polish doesn’t restore sheen.

Step 3 – Apply Quartz Polish

Use a specially formulated quartz polish to remove minor etching and restore the surface luster.

  • Shake polish bottle to mix contents before using according to manufacturer’s instructions.
  • Apply a small amount directly onto the quartz surface.
  • Using a soft buffing pad, work the polish over the surface using circular motions.
  • Be sure to maintain even pressure and frequently reapply polish as needed.
  • Pay close attention to any etched or dull areas to ensure they are adequately polished.
  • Avoid having polish dry on the surface. Keep it moist.

Pro Tip: Always test polish in an inconspicuous area first to ensure it does not stain or interact with the quartz.

Step 4 – Buff to a Shine

Once the polish has been worked over the entire surface, switch to a clean microfiber cloth to buff the quartz and remove any polish residue.

  • Buff in broad, circular motions using moderate pressure.
  • Frequently fold cloth to expose clean areas for buffing.
  • Continue until cloth slides smoothly over the surface.
  • Flip cloth and make final light passes over entire countertop to finish.

Note: Avoid using excessive pressure when buffing, as this can create minor scratches. The goal is to generate friction to warm and level the surface, not abrasion.

Step 5 – Seal and Protect (Optional)

For added shine and protection, consider applying a quartz sealer after polishing.

  • Use a microfiber applicator and apply a thin, even layer according to product instructions.
  • Allow sealer to cure fully before use, typically requiring 24 hours.
  • Sealer will help resist fingerprints, stains, and dulling from everyday use.
  • Reapply sealer every 1-2 years as needed.

Tips for Polishing Quartz

  • Always test products on a small, inconspicuous area first.
  • Work in sections when polishing large countertops.
  • Avoid applying excessive pressure which can damage the surface.
  • Change buffing cloths frequently to prevent haze and streaks.
  • Make sure quartz is completely clean and dry before polishing.
  • Consider engaging a professional if heavy etching is present.

Common Quartz Polishing Questions

What causes quartz countertops to lose their shine?

Quartz can develop a dull or etched appearance over time from general wear and tear. Exposure to acidic foods, abrasive cleaners, hard scrubbing, and objects left on the surface can damage the finish.

How often should I polish my quartz?

For residential use, a thorough polish every 1-2 years is usually adequate to maintain the finish. Quartz used in commercial settings may need more frequent polishing every 6-12 months.

Can I use a power polisher?

Yes, you can safely use a variable speed power polisher for quicker polishing results. Use a low speed setting and work carefully to avoid excessive heat or pressure. Always hand polish near edges.

Should I seal my quartz countertop after polishing?

Sealing is an optional protective step that can help prevent stains and etching between polishes. It will also provide added shine and easier cleaning. Reapply sealer every 1-2 years.

What’s the best polish for quartz?

Look for polishes specifically formulated for quartz rather than natural stone polish. Trusted brands include Mother’s, TriNova, Black Diamond, and Stonetech. Always check label to verify compatibility with quartz.


With a little time and elbow grease, you can restore the beautiful factory finish to dull quartz countertops. By using quality quartz polish and proper buffing techniques, minor scratches and etching can be removed to regain the glossy surface. Just be sure to thoroughly clean the quartz first and test products in an inconspicuous spot before polishing the entire surface. With regular care and maintenance polishing, your quartz countertops will stay looking like new for years to come.
