How to Remove Scratches from Quartz Countertop

Quartz countertops are popular in many homes due to their durability, stylish appearance, and low maintenance. However, like any surface, quartz can get scratched and damaged over time. Thankfully, there are ways to remove light scratches from quartz countertops without damaging the material or finish. Here is a comprehensive guide on how to remove scratches from quartz countertops.

What Causes Scratches on Quartz?

Quartz is an engineered stone made from crushed quartz crystals combined with resins and pigments. While it’s resistant to scratches, cuts, and stains compared to other countertop materials, quartz can still get surface damage under certain conditions:

  • Dragging heavy, abrasive objects like pots, appliances, etc. across the surface
  • Not using a cutting board and slicing food directly on the countertop
  • Harsh cleaners and scrubbing pads wearing down the finish
  • Dropping sharp objects that can chip or gouge the material

Scratches on quartz range from minor surface marks to deeper grooves that penetrate the finish and expose the lighter quartz underneath. The good news is that light surface scratches can be removed with the right techniques and care.

Cleaning vs. Scratch Removal

It’s important to distinguish between regular cleaning and scratch removal. Simple cleaning can be done by:

  • Wiping down with a soft, damp cloth or sponge and mild soap/detergent
  • Rinsing thoroughly and drying with a soft towel
  • Avoiding harsh cleaners like bleach, ammonia, etc.

However, this light cleaning will not remove or repair existing scratches. Scratch removal requires a more intensive process of gently sanding and polishing the damaged area specifically.

Step-By-Step Guide to Remove Scratches

Here is a foolproof method to remove minor-to-medium scratches from your quartz countertop:

1. Clean and Dry the Surface

Give the countertop a thorough cleaning using a mild detergent and warm water to remove dust, debris and oils. Rinse well and dry completely with a soft cloth. Make sure the countertop is totally dry before moving on.

2. Sand the Scratched Area

Use extra-fine grit sandpaper (1000+ grit) and gently sand the scratched area using small circular motions. Apply light pressure and keep the sanding localized only to the scratches.

Be patient and keep sanding until the deeper scratches are minimized and the sanded area blends into the rest of the countertop.

3. Smoothen Edges

Use a soft rag to wipe away all sanding residue. If there are any uneven edges around the sanded areas, smoothen them out with a fine grit sanding sponge.

4. Polish to Finish

Use a quartz polish or concrete polish and apply it directly onto the sanded areas. Rub it in using gentle motions.

Allow the polish to dry completely and cure according to the manufacturer’s instructions.

Finally, buff the area with a soft cloth until you achieve an even glossy finish.

5. Seal and Protect

Apply a food-safe sealer to the entire countertop surface to seal and restore gloss. Re-apply sealer periodically to reinforce protection.

Always use cutting boards, trivets and be mindful of dragging appliances to prevent future scratching.

Tips and Precautions

  • Test sand and polish on a small inconspicuous area first to ensure it doesn’t damage the surface further.
  • Use a sanding block instead of doing it by hand for better control and even sanding.
  • When sanding, always maintain the original contour and finish.
  • Avoid sanding too aggressively in one area to prevent dipping or uneven spots.
  • If the scratches are too deep and extensive, hire a professional fabricator/refinisher.
  • Superficial micro-scratches can be removed just using polish and sealant. No sanding needed.
  • Use high-quality products specifically meant for quartz. Cheap DIY kits can ruin the finish.
  • If you can catch the scratch when it first happens, rubbing a damp cloth over it can minimize the mark.
  • Protect sanded areas from cleaning chemicals until fully cured and sealed.

With some care and effort, you can successfully remove annoying scratches from quartz countertops and restore their smooth, flawless finish. Just be sure to follow the proper sanding and polishing techniques. Quartz is quite forgiving compared to other natural stone surfaces.

Frequently Asked Questions

How can I determine if a scratch can be removed at home or needs a pro?

Minor surface scratches that don’t catch your fingernail can likely be sanded and polished out. Deep scratches penetrating the finish need a trained fabricator with equipment to resurface. If you are unsure, start with a small test spot.

What sandpaper grit should be used on quartz?

Use at least 1000 grit or higher extra-fine sandpaper. Anything more abrasive can damage quartz. Hand sand in a controlled manner or use an orbital sander on low speed.

Is there a homemade scratch remover solution for quartz?

Baking soda and lemon juice can help lighten and minimize scratches due to their weak abrasive properties. However, they cannot fully remove deeper scratches. Sanding and polish is still required for best results.

Can I use a car polish or buffing compound on quartz countertops?

No, avoid automotive polishes. Use a high quality quartz polish specifically designed for engineered stone. It contains delicate abrasives to refine the surface without causing swirl marks.

How long does the scratch removal process take?

It depends on the severity and extent of damage, but minor scratches can be removed in about an hour. Allow additional time for sealing, curing and drying as required.

Will this process ruin the countertop finish or shine?

Done properly, it will restore the original factory finish. The key is to sand minimally and keep polish application thin and even. Proper sealing also brings back the shine.


Scratches on quartz countertops are unfortunately inevitable over time. But with the right tools and techniques, you can successfully minimize and remove superficial scratches at home without damaging the countertop further. Just remember to:

  • Keep sanding localized and even
  • Smoothen out edges
  • Use specialized quartz polish
  • Seal and protect the finish

With some care and effort, you can erase those pesky marks and regain your countertop’s flawless look and luster. Handle any deep gouges by calling in a professional fabricator. And reinforcing the sealant periodically will help prevent future scratches.
