How to Get Rust Out of a Quartz Countertop

What Causes Rust Stains on Quartz?

Quartz countertops contain natural quartz crystals combined with resins and pigments. While quartz is non-porous and resistant to stains, rust stains can still occur due to:

  • Iron particles in water settling on the surface
  • Iron cookware or utensils resting on the countertop
  • Using iron-containing cleaning products
  • High humidity encouraging rust formation

Rust specifically comes from iron that has been exposed to moisture and oxygen. Preventing rust involves keeping iron sources away from the quartz and thoroughly drying any water that gets on the surface.

Cleaning Rust Stains from Quartz

Try a Poultice

Making a poultice is one of the most effective ways to draw rust stains out of quartz. A poultice actively pulls the stain out from the pores of the stone. Here is a simple rust stain remover poultice you can make at home:

What You Need:

  • Baking soda
  • Hydrogen peroxide
  • Paper towels

Steps to Make the Poultice:

  1. In a bowl, mix a paste using 3 parts baking soda to 1 part hydrogen peroxide. Adjust consistency as needed – it should form a spreadable paste.
  2. Apply the poultice paste generously over the rust stain using a paper towel or plastic applicator.
  3. Cover the poultice with plastic wrap and tape down the edges to seal it. This prevents the poultice from drying out.
  4. Leave the poultice on for 24-48 hours. Reapply if it dries out.
  5. Remove the plastic and gently scrape off the poultice. Rinse the area clean.

The baking soda and peroxide work together to oxidize and lift the rust stain from the quartz. With a strong poultice, you should see a lightening or complete removal of the stain after the first application.

Use a Rust Remover Chemical

For more stubborn stains, use a commercial rust remover designed for stone. Products like StoneTech Rust Remover, Howard Restor-A-Finish and Whink Rust Stain Remover work well on quartz.

To use:

  • Read and follow all instructions on the bottle.
  • Apply a generous amount directly onto the rust stain.
  • Let it sit for 5-10 minutes.
  • Scrub with a soft brush or plastic scouring pad.
  • Rinse thoroughly.
  • Repeat as needed until the rust stain lightens or disappears.

The acids and chelating agents in commercial removers help dissolve and lift away rust stains. Just take care not to leave the product on the quartz too long as it can etch the surface.

Try Other Home Remedies

Some common household products can also work to get rust stains off quartz:

  • Lemon juice – Contains citric acid to dissolve rust. Let it sit for 30 mins.
  • White vinegar – Also has acetic acid. Mix 1:1 with water and apply.
  • Oxalic acid – Found in wood bleach. Follow instructions and rinse thoroughly after.
  • Salt – Acts as a gentle abrasive. Make a paste and scrub.

Always spot test home remedies first on an inconspicuous area to ensure they don’t damage the quartz. And rinse immediately if you see any etching taking place.

Tips to Prevent Rust Stains on Quartz

Prevention is key when it comes to keeping quartz rust-free. Here are some handy tips:

  • Wipe up spills immediately, especially anything acidic like wine or juice.
  • Avoid leaving iron cookware sitting directly on quartz. Use a trivet or mat.
  • Seal and reseal quartz regularly with a stone sealer.
  • Use coasters under flower pots or vases.
  • Run the exhaust fan when cooking to reduce moisture buildup.
  • Keep humidity low in the kitchen.
  • Clean with non-abrasive pH-neutral cleaners.

With regular care and prompt cleaning when stains occur, you can keep your quartz counters rust-free and looking like new for years. Get ahead of rust stains by using preventive measures, and use poultices, removers and home remedies to successfully remove any stains that do show up. With a little time and elbow grease, you can get rid of rust on quartz countertops.

Frequently Asked Questions About Removing Rust from Quartz Countertops

How long does it take to remove rust stains from quartz?

It can take anywhere from 30 minutes to 24-48 hours depending on the stain remover used. Poultices need to be left on for a full day to work. Chemical removers act more quickly within 5-10 minutes.

What is the easiest way to get rust off quartz?

Making a simple poultice using baking soda, hydrogen peroxide and water is the easiest, safest method. It’s made with common household items and is free of harsh chemicals. Just mix, apply to the stain, let sit, then rinse.

Can I use CLR to remove rust from quartz?

No, CLR and other acidic cleaners should be avoided on quartz. The acids can damage and etch the surface. Use a rust remover specifically formulated to be gentle on stone instead.

Will Magic Erasers remove rust stains from quartz?

Magic Erasers can potentially scratch or dull the surface of quartz, so they are not recommended. Use a soft brush or plastic scouring pad instead for light scrubbing. The eraser’s melamine foam is too abrasive for quartz.

What kind of vinegar removes rust from quartz?

White distilled vinegar is best for removing rust from quartz. Apple cider vinegar and other types with added color or sediment can stain. Mix white vinegar with equal parts water and wipe onto the stain. Let sit briefly before rinsing.


Rust stains on quartz countertops are common but can luckily be removed with the right techniques. By making a simple poultice, using commercial removers formulated for stone, or trying mild home remedies, you can eliminate those unsightly rust marks. Be sure to take steps to prevent future stains by sealing the quartz and keeping iron sources away. With a little periodic maintenance, your quartz counters will stay looking like new for many years.
