How to Buff Out Marks on Quartz Countertops

Quartz countertops are an increasingly popular choice for modern kitchens and bathrooms due to their durability, ease of maintenance, and stylish appearance. However, like any surface, quartz can get scratched and marked over time. Small scratches and marks can often be buffed out through a simple DIY process. Here is a step-by-step guide on how to buff out marks on quartz countertops.

What You’ll Need


  • 2000-3000 grit wet/dry sandpaper
  • Microfiber cloths
  • Soft polishing pad

Polishes and sealers:

  • Countertop polish
  • Countertop sealer

Other supplies:

  • Water or denatured alcohol for wet sanding
  • Rags
  • Rubber gloves
  • Safety goggles
  • Dust mask

How to Buff Out Light Scratches

Step 1: Clean the countertop

Before buffing, make sure the countertop surface is free of dirt, grease, and debris that could cause further scratching. Clean with a mild detergent, rinse thoroughly, and let dry.

Step 2: Wipe with denatured alcohol

Use a lint-free cloth soaked in denatured alcohol to remove any waxes or residue. This helps the polishing compounds penetrate.

Step 3: Start wet sanding with 2000 grit sandpaper

Wet the surface and sand in a circular motion with medium pressure. Check often to see if the scratch is disappearing. Move to a finer 3000 grit if needed.

Step 4: Wipe away sanding residue

Make sure to carefully wipe away all sanding residue with a damp microfiber cloth after sanding before moving to polishing.

Step 5: Polish the sanded area

Use a soft polishing pad with a bit of countertop polish and buff in widening concentric circles until the shine is restored. Take care not to over-polish any one area.

Step 6: Clean and seal the countertop

Remove all polish residue and use a microfiber cloth to apply 2-3 thin coats of countertop sealer to help protect the finish. Allow sealer to fully cure between coats.

How to Remove Stubborn Marks on Quartz

If simple buffing doesn’t remove deeper scratches or stubborn marks, try these tips:

  • For marks or etching, try a poultice made of pH neutral cleaner and whiting powder. Apply a thick paste over the mark, cover in plastic wrap, and let sit for 24 hours before scrubbing clean.
  • Use a razor blade scraper held at a 30° angle to gently scrape off adhesives, paints, or hardened materials. Move blade with the grain of the stone.
  • Try a specialty quartz polishing compound if other polishes don’t work. Use a buffing pad and buff in a swirling pattern until the mark is gone.

Tips for Preventing Marks on Quartz Countertops

  • Use cutting boards and hot pads to protect the surface from knives, pots, etc.
  • Immediately wipe up spills, especially acidic substances like wine or fruit juice.
  • Avoid abrasive cleaners and scouring pads which can dull the finish.
  • Reseal quartz countertops every 1-2 years to protect the finish.
  • Don’t place hot pots or pans directly on the quartz surface.

With a little time and effort, you can keep your quartz countertops looking like new. Just be sure to address any scratches or marks as soon as possible before they worsen or become permanent. With the right techniques, you can often buff them out yourself without having to hire a professional.
