Can You Repair Scratched Quartz Countertops?

What Causes Scratches on Quartz?

There are a few common causes of scratches on quartz surfaces:

  • Cutting or chopping on the countertop – Using a countertop as a cutting board can easily scratch the surface, even though quartz is very hardy. Always use a separate cutting board.
  • Dragging heavy or sharp objects across the surface – Appliances, pots and pans, tools, etc can all leave scratches if dragged across the quartz. Lift objects to move them instead.
  • Diamonds and other hard minerals – Believe it or not, materials like diamonds used in jewelry can scratch quartz. Keep abrasive jewelry and accessories in a drawer instead.
  • Sand and grit – Tiny particles of sand, salt, dirt and grit act like sandpaper on quartz surfaces, slowly causing fine scratches over time. Clean spills quickly to minimize damage.
  • Improper cleaning – Using abrasive cleaners, scouring pads, or applying too much pressure while cleaning can also mar and scratch quartz. Use only soft cloths and mild cleaners.

Repairing Light Surface Scratches on Quartz

If your quartz countertop has minor scratches but has not lost any actual stone material, the scratches can likely be minimized or removed. Here are some DIY methods to repair light surface scratches:

Sanding and Polishing

Using fine grit sandpaper and polish can help reduce the appearance of light scratches. Start with a 400 grit sandpaper and gently sand the area in circular motions. Move up through finer grits, like 800 and then 1500 grit, sanding until the scratches are less noticeable. Finish by buffing the sanded areas with a quartz polish to restore the surface shine.

Buffing Pads

Special buffing pads designed for stone can also help polish away light scratches. Use a buffing pad together with a stone polish and buff the scratched areas until the scratches fade. Take care not to over-buff, which can create uneven spots.

Baking Soda Paste

For very fine hairline scratches, make a paste with baking soda and water. Apply the paste to the scratches with a soft cloth and rub in a circular motion. Rinse thoroughly afterwards and dry. Baking soda is a mild abrasive that can remove minor blemishes.

Mr. Clean Magic Eraser

Magic Erasers utilize melamine foam to safely lift away marks on stone surfaces. Lightly dampen a Magic Eraser and gently rub stained or scratched areas. It will gently abrade the surface without damaging the stone. Rinse after use.

Repairing Deeper Scratches and Gouges

If a quartz countertop is scratched deeply enough that material has been removed, repairs become more complex. Deep scratches may require:

  • Filling in with a specialty quartz filler product
  • Grinding down the surface to remove deeper scratches
  • Full spot replacement of the damaged quartz areas

For best results with deeper repairs, consider hiring a professional quartz fabricator or technician. Improper repairs can result in further damage or very obvious patch marks.

Protecting Quartz from Future Scratches

To minimize future scratches on your quartz surfaces:

  • Use cutting boards and hot pads whenever prepping food or placing hot items on quartz.
  • Clean up spills quickly, especially gritty substances like sugar or salt that can cause abrasion.
  • Avoid using knives or sharp objects directly on the quartz.
  • Use placemats and coasters under dishes and glasses.
  • Apply a granite and quartz sealer annually to protect from stains and etching.

With proper care and regular sealing, quartz countertops should remain resilient for many years before needing repairs. But when scratches eventually occur, know that there are options to refresh the surface again. Pay attention to prevent deep damage, and address light scratches promptly by sanding, polishing or using other DIY remedies. For major repairs, consult a professional fabricator. With some care and effort, your quartz countertops can look like new again.
