How to Remove Metal Marks from Quartz Countertops

What Causes Metal Marks on Quartz?

Quartz is made from natural stone materials and resin. While it is resistant to stains, heat, and scratches, it can still get damaged by sharp metal objects like knives, pans, keys, belt buckles etc. The metal leaves grayish marks or scratches on the surface. Copper, iron, and steel are the most common culprits.

Prolonged contact with metal can permanently stain or etch your quartz. The marks may look like bruises, scratches, or discoloration. Avoid placing hot pans directly from the stove or abrasive scouring pads on the countertop. Trivets and hot pads should always be used.

Best Methods to Remove Metal Marks from Quartz

1. Baking Soda and Water Paste

Baking soda is a mild abrasive that can buff out metal marks effectively. Just make a paste using 3 parts baking soda and 1 part water. Apply it directly on the marks and let it sit for 5 minutes. Wipe off with a soft cloth and rinse with plain water. The abrasive texture removes the discoloration without damaging the quartz.

2. Mr. Clean Magic Eraser

Magic erasers contain melamine foam that easily takes off metal stains with minimal scrubbing. Wet the eraser and gently rub it over the marks in a circular motion. It will lift off the grayish discoloration. Make sure to rinse with water afterwards. Be careful not to overdo it as the eraser can potentially cause surface damage.

3. Bar Keeper’s Friend

This popular household cleaner contains oxalic acid and abrasives that can eliminate all kinds of marks from quartz. Make a paste by mixing the powder with water. Apply it on the stained spot and leave for 5 minutes before scrubbing with a damp sponge or cloth. Rinse thoroughly. Repeat if needed for stubborn stains. It can also be used on a variety of other surfaces.

4. Vim Cream or Soft Scrub Cream Cleanser

Cleaning creams containing bleach like Vim and Soft Scrub do wonders for removing metal marks. Apply a small amount directly on the stain and scrub with a non-abrasive sponge. Allow it to sit briefly before wiping down. Bleach can lighten or discolor some quartz so spot test first.

5. Automotive Buffing Compound

Very light buffing using a plastic polishing pad and automotive rubbing compound can take out superficial metal marks. Use light pressure and buff in circular motions. Avoid applying too much pressure to prevent damage to the quartz finish. Follow up with a stone polish to restore the quartz shine.

Tips to Prevent Metal Marks on Quartz

  • Use cutting boards, trivets and hot pads when preparing food or placing hot items on quartz.
  • Clean spills immediately to prevent staining and etching.
  • Avoid abrasive pads, powders or harsh cleaners.

Can All Metal Marks on Quartz Be Removed?

With some care and effort, your quartz countertops can look as good as new again and continue providing years of trouble-free service. Be sure to address any metal marks right away before they have a chance to set and stain. Consistent cleaning and prompt attention to damages will keep your quartz surfaces in impeccable shape.
