How to Get Black Marks Off White Quartz Countertops

What Causes Black Marks on Quartz?

There are a few common culprits of black marks on white quartz:

  • Dyes from fabrics: Items like jeans or towels that have been dyed black can leave residue when they come into contact with the countertop. The dye can transfer.
  • Ink and pen marks: Writing on the countertop, even accidentally, can leave inky black residue. Permanent markers are especially prone to staining.
  • Scuffs and burns: Hot pots/pans, especially cast iron, can scorch the surface leaving black scuffs. Hard impacts can also discolor the texture.
  • Mold/mildew: Moisture that doesn’t drain well on the countertop can allow mold to grow leaving black spots.
  • Everyday grime: General dirt, oil, and grease buildup leads to dull dark areas on the quartz.

Cleaning Methods to Remove Black Marks

Here are some methods to try removing black marks from quartz countertops:

1. Baking Soda and Water Paste

  • Make a paste of baking soda and water. Apply it to the black marks.
  • Let it sit for 5-10 minutes to lift the stain.
  • Scrub with a soft cloth or sponge.
  • Rinse thoroughly afterwards.
  • Baking soda is a mild abrasive that can break down staining without damaging the quartz.

2. Hydrogen Peroxide

  • Apply hydrogen peroxide directly onto the marks.
  • Let it bubble on the stain for 2-5 minutes.
  • Wipe away with a damp cloth.
  • Hydrogen peroxide is a bleaching agent that can lighten dark stains.

3. Bar Keepers Friend

  • Sprinkle some Bar Keepers Friend cleanser onto the marks.
  • Add just enough water to make a paste.
  • Gently scrub the area using a sponge or soft rag.
  • Rinse thoroughly afterwards.
  • Bar Keepers contains oxalic acid to lift stains and abrasives to scrub them away.

4. Dish Soap and Baking Soda

  • Make a thick paste with dish soap, baking soda, and water.
  • Apply the paste to the marks and let sit for 5 minutes.
  • Scrub with a soft cloth, using a circular motion.
  • Rinse thoroughly with clean water.
  • The soap helps break up oils and grease while baking soda lifts stains.

5. Mr. Clean Magic Eraser

  • Dampen a Magic Eraser slightly and directly scrub the black marks.
  • Apply light pressure and use a circular motion.
  • Rinse thoroughly after scrubbing.
  • The melamine foam construction acts as a mild abrasive to remove staining.

Tips for Preventing Black Marks

Prevention is also key to keeping quartz pristine:

  • Use cutting boards and trivets when prepping food or placing hot items on the countertop.
  • Clean up spills immediately before they have a chance to set.
  • Routinely clean quartz with a gentle stone cleaner.
  • Avoid using dyes, inks, and permanent markers directly on the surface.
  • Seal quartz every 6-12 months to protect from stains.

When to Call for Professional Help

If you’ve tried these methods without success removing the black marks, contact a professional stone restoration company. They have access to more powerful cleaning systems like:

  • Pressurized air systems to deeply clean pores.
  • Industrial polishers with diamond abrasives to resurface etching.
  • Commercial degreasers to cut through deep oil stains.

With the right cleaning methods, you can restore the pristine white look of your quartz countertops and keep black marks at bay. Be gentle yet persistent, and reach out to a pro if DIY efforts fail. Keeping quartz looking like new takes regular care and maintenance.

Frequently Asked Questions About Removing Black Marks from White Quartz Countertops

Can I use bleach to remove black marks from white quartz?

No, avoid using bleach or other harsh chemicals like oven cleaners on quartz countertops. The caustic components can actually damage and discolor the surface further. Milder agents like hydrogen peroxide are safer options.

What about magic eraser sponges?

Magic erasers can be used safely on quartz if used gently. Dampen the sponge first and rub in circular motions. Avoid excessive scrubbing pressure which can wear down the surface over time.

How do I get rid of black scuffs from pots and pans?

For black burnt marks from pots and pans, spray some glass cleaner on the mark and let it soak for 2-3 minutes. Use a plastic putty knife to gently scrape the scorched areas off. Rinse with clean water afterwards.

Why does my white quartz look dull and dirty?

Dirt, oil, and daily usage can cause quartz to appear dull and dirty looking over time. Regularly clean with a granite or quartz cleaner to remove grime buildup. A professional deep cleaning can also help rejuvenate the look of foggy quartz countertops.

Are there any DIY poultice options for removing stains?

Yes, you can make a poultice using baking soda, hydrogen peroxide, and powdered dishwasher detergent. Mix to form a paste, apply to the stain for 1-2 hours, then rinse. This can help draw out deep oil-based stains.


White quartz offers a bright, fresh look but also requires attention to keep looking its best. Using the right techniques to promptly clean black marks keeps the surface pristine. Gentle yet persistent effort with non-abrasive cleaners works on most stains. For stubborn spots, call on a professional stone cleaner to revitalize the countertops. With regular care, white quartz countertops will maintain their beauty.
