How to Polish Scratches Out of a Quartz Countertop


Quartz countertops are popular choices for kitchens and bathrooms due to their durability, low maintenance, and stylish appearance. However, like any surface, quartz can get scratched and damaged over time. Small scratches are inevitable, but with the right techniques and products, you can minimize and even remove scratches from your quartz countertops.

Supplies Needed

Before starting to polish out scratches, make sure you have the proper supplies:

  • Microfiber cloths
  • Soft cleaning rag
  • Mild liquid dish soap
  • Countertop polish or sealant
  • Extra fine 0000 steel wool
  • Plastic putty knife
  • Soft polishing pad
  • Clean water

Clean the Surface

The first step is thoroughly cleaning the countertop. This will remove any dirt or debris that could interfere with the polishing process.

  • Mix a few drops of mild dish soap with warm water in a spray bottle.
  • Spray the cleaning solution directly onto the countertop surface.
  • Use a soft cleaning rag to wipe down the entire countertop.
  • Rinse with clean water and dry completely with a microfiber cloth.

Identify the Severity of the Scratches

Not all scratches are the same. Before polishing, determine if the scratches are deep or superficial.

  • Superficial scratches are light surface marks that you can catch with your fingernail. These can often be polished out.
  • Deep scratches cut down into the quartz and cannot be removed through simple polishing. These may require a professional resurfacing.

Polish Superficial Scratches

For light surface scratches, use an extra fine 0000 steel wool pad:

  • Dampen the steel wool slightly with water.
  • Gently rub the steel wool in circular motions over the scratch. Apply light pressure.
  • Check periodically to see if the scratch has lessened.
  • When satisfied, wipe away any steel wool fragments with a dry microfiber cloth.

You can also use a soft polishing pad designed for stone surfaces. Rub it over the scratches using minimal pressure.

Use Countertop Polish or Sealant

For enhanced results, apply a specialty countertop polish or sealant:

  • Choose a polishing product specifically made for quartz.
  • Apply a small amount directly onto the scratched area using a clean, soft cloth.
  • Rub gently in a circular motion.
  • Remove any excess product and buff to a shine.
  • Allow the polish to dry completely.

The polishing agents help smooth over superficial marks on the surface while the sealant adds a protective barrier.

Employ a Plastic Putty Knife for Stubborn Marks

For more stubborn, shallow scratches:

  • Carefully scrape the edge of a new plastic putty knife over the length of the scratch.
  • Apply light, even pressure and work slowly.
  • Follow up by rubbing with steel wool or polishing pads.
  • Be cautious not to gouge the surface.

Prevent Future Damage

To help avoid future scratches:

  • Use cutting boards and hot pads when preparing food.
  • Clean spills promptly with a soft cloth.
  • Avoid abrasive cleansers.
  • Don’t place hot pans directly on the quartz.
  • Apply sealant every 6 months.
  • Install felt or rubber pads under appliances.

When to Call a Professional

If you have any deep gouges, chips, or cracks in the quartz, stop polishing attempts and call a professional countertop refinishing company. Aggressive DIY efforts could cause further damage. Professionals have specialized techniques and tools to repair or resurface badly damaged quartz countertops.

Frequently Asked Questions

Can I use baking soda or vinegar to polish out scratches?

No, baking soda and vinegar are too abrasive for quartz and can damage the surface further. Mild dish soap and water is best for cleaning before polishing.

What household items can I use to polish small scratches?

Soft cloths, extra fine steel wool, and plastic putty knives often work well for minor marks. Avoid abrasive scrub sponges or brushes.

How can I restore the shine?

Applying a countertop polish or sealant helps fill in micro-scratches and restore quartz’s beautiful gleaming finish.

Is there a scratch repair kit for quartz?

Yes, many companies sell DIY quartz scratch repair kits. These contain specialty polishing compounds, pads, and sealants designed specifically for quartz surfaces.

Can I polish out scratches myself or do I need a professional?

For light surface scratches, DIY polishing is often successful. But deep scratches or extensive damage requires a trained countertop refinishing technician.


Quartz countertops develop scratches over time, but many light surface marks can be minimized with the right polishing techniques. Thorough cleaning, using steel wool, plastic putty knives, and countertop polishes can help reduce the appearance of superficial scratches. Prevent future damage with cutting boards, prompt cleaning, and furniture pads. Call in a professional when scratches are too deep for DIY methods. With some patience and effort, you can restore the beautiful, flawless look of your quartz countertops.
