How to Fix a Scratched Quartz Countertop

Assessing the Damage

Not all scratches are created equal when it comes to quartz countertops. Here are some things to consider when inspecting the scratch:

  • Depth – Surface level scratches are easier to fix than deep grooves. Use your fingernail to gauge depth.
  • Location – Scratches in high traffic zones may require more intensive repairs.
  • Severity – Minor scratches may blend away with minimal effort. Severe scratches or gouges need professional help.
  • Pattern – Are the scratches random or directional? Directional scratches may need special sanding techniques.
  • Finish – Is the scratch in a polished or textured finish? You’ll need products suited for each.

Figuring out the specifics of the scratch damage will dictate the repair strategy.

Cleaning and Prepping the Surface

Before doing any scratch repairs, thoroughly clean and dry the countertop. Remove all dirt, grime, sealers, waxes or other residues:

  • Use a gentle countertop cleaner and soft cloth/sponge. Avoid abrasive cleansers.
  • For stubborn spots, try a mild degreasing dish soap diluted in warm water.
  • Rinse several times and dry thoroughly with a soft cloth. Residual moisture can impact scratch fillers.

Proper cleaning exposes the full extent of the scratches for better assessment and repair.

DIY Fixes for Minor Scratches

Minor surface level scratches can often be minimized using everyday household products:

Baking Soda or Stone Polish

Gently rub a paste of baking soda and water over the scratches using a soft cloth or sponge. The abrasive yet fine texture helps blend away imperfections. Alternatively, use a pre-made quartz polish product.

Vegetable Oil

Apply a small amount of oil over the scratches and allow it to sit for 10-15 minutes. Wipe away the oil and grime should come with it. Repeat as needed.


Use a non-gel toothpaste and rub over scratches with a soft brush or sponge. Rinse thoroughly after. The mild abrasives can help blend away surface flaws.

Window Cleaner

Spray window cleaner like Windex directly onto scratches and allow it to sit for several minutes. The ammonia in the cleaner helps break down residues lodged in scratches.

Be patient and gentle with these homemade remedies. It may take several applications to achieve the desired results.

Repairing Deeper Scratches

For more severe scratches that catch a fingernail, more advanced repair techniques are required:

Scratch Repair Kit

Purchase a quartz countertop scratch repair kit. These contain specialized abrasives to sand down scratches along with an adhesive filler to rebuild the scratched area. Follow kit instructions carefully.

Color Putty Stick

This is a putty stick that matches the color of your countertop. Fill deeper scratches with putty, allow to dry, then scrape flush. Apply an adhesive wipe over top to smooth.

Clear Epoxy

For narrow but deep scratches, carefully fill with a clear drying epoxy resin specifically designed for quartz repairs. Remove any excess before drying.

Professional Help

For extreme scratches, gouges, chips or cracks, consult a professional countertop repair specialist. They have commercial grade tools and repair products to fix significant damage.

Be very meticulous when using abrasives on quartz. It’s easy to damage the surrounding areas. Take your time and closely follow product instructions.

Preventing Future Scratches

To help avoid new scratches on your quartz countertops:

  • Use cutting boards, hot pads and trivets when prepping food. Never cut directly on the quartz.
  • Don’t drag cookware or appliances across the surface. Lift and set down carefully.
  • Apply wax or sealant regularly with a soft cloth to help protect from superficial scratches.
  • Immediately clean spills, especially acidic substances that can etch the quartz surface over time.
  • Avoid harsh cleaning products. Use a gentle stone cleaner and soft sponge for daily cleaning.

With proper care and maintenance, quartz countertops will stay looking beautiful for years. But when scratches inevitably occur, follow these repair tips to restore your quartz surface.

Frequently Asked Questions About Fixing Scratched Quartz Countertops

Can I use sandpaper to remove scratches from my quartz countertop?

It’s not recommended to use regular sandpaper on quartz countertops. The grit is often too coarse and sanding incorrectly can further damage the surface. Instead, look for specialty quartz sanding blocks and pads designed for superficial scratch removal without harming the surrounding material.

What household items can fix scratches?

For mild surface scratches, try a baking soda paste, mineral oil, toothpaste, or ammonia-based window cleaner. Gently rub onto scratches using a soft cloth. Be patient – it may take several applications. Avoid harsh abrasives like metal scouring pads.

Should I try and polish out scratches myself?

Only attempt polishing if the scratches are minor. Use a quartz-specific polishing compound and buff gently with a soft pad. Trying to polish out deeper scratches can expose uneven areas and make the problem worse. Severe damage requires pro help.

What’s the difference between etching and scratching quartz?

Scratches are physical surface damage from things like cutlery or dragging appliances. Etching is chemical damage from substances like juice or cleaners “burning” into the surface. Etching appears as large cloudy patches – scratches are visible grooves.

How can I prevent future scratches on my quartz countertop?

Use cutting boards, trivets and hot pads when prepping food. Clean spills quickly, especially acidic ones. Apply wax or sealant regularly for added protection. Avoid dragging objects across the surface. Daily cleaning with a soft sponge and mild soap will also help.


Scratches in quartz countertops range from minor surface flaws to deep gouges. Assessing the type of damage is the first step. Gentle abrasives, filler putties and sanding pads can help fix many common scratches. But be cautious when attempting DIY repairs on expensive countertop surfaces. Prevent future scratches through proper kitchen care and maintenance. With some persistence, those annoying quartz scratches can be diminished for a beautiful, flawless countertop surface.
