What Takes Rust Off Quartz Countertops

Quartz countertops are a popular choice for kitchens and bathrooms due to their durability, aesthetics, and low maintenance. However, like any surface, quartz can be susceptible to rust stains over time. Removing rust from quartz requires using the right products and techniques to avoid damaging the material. Here is a comprehensive guide on what takes rust off quartz countertops.

What Causes Rust on Quartz Countertops

There are a few common causes of rust stains on quartz countertops:

  • Metal objects like pots, pans, and utensils resting on the surface can transfer rust over time. The iron in the metal reacts with moisture in the air, causing oxidation (rust).
  • Spilled liquids like wine, fruit juices, and vinegar contain acids that can react with iron deposits on the surface and cause discoloration.
  • Hard water contains a high mineral content. As the water evaporates, it leaves behind mineral deposits on the countertop that can rust.
  • Exposure to humidity and moisture, especially around sinks and faucets, facilitates rust formation.

How to Remove Rust Stains from Quartz

Removing rust from quartz requires gently abrasive cleaning solutions that can dissolve the rust without damaging the surface. Here are the most effective methods:

Clean with Baking Soda and Water

  • Make a paste by mixing 2-3 tablespoons of baking soda with some water.
  • Use a soft cloth or sponge to gently rub the paste onto the rust stain.
  • Let it sit for 5 minutes before rinsing with clean water and drying with a soft towel.
  • Baking soda is mildly abrasive to lift rust but safe for quartz.

Use Lime Juice and Salt

  • Squeeze fresh lime juice directly onto the rust stain.
  • Sprinkle some table salt on top and use a soft cloth to rub the mixture into the stained area.
  • Let it sit briefly before rinsing and drying the surface.
  • The citric acid in lime juice dissolves rust, while salt provides gentle scouring.

Clean with Vinegar

  • Undiluted white vinegar can help dissolve and break down rust spots.
  • Pour a small amount directly on the stain and let it soak for 10-15 minutes.
  • Wipe away the vinegar and rinse thoroughly with water.
  • Vinegar is an acidic cleaner that removes rust without damaging quartz.

Use Hydrogen Peroxide and Baking Soda

  • Mix 2 tablespoons of hydrogen peroxide with enough baking soda to form a paste.
  • Gently spread the mixture over the stained area using a soft-bristle toothbrush.
  • Allow it to bubble for a few minutes before rinsing thoroughly.
  • Hydrogen peroxide whitens and lifts stains while baking soda scrubs.

Clean with Oxalic Acid

  • Oxalic acid is an effective rust remover and can be purchased as a powder or liquid solution.
  • Carefully apply a small amount directly to the rust stain.
  • Rinse thoroughly after 5 minutes.
  • Use gloves when handling oxalic acid as it can irritate skin.

Tips for Preventing Rust on Quartz

Along with knowing how to remove rust stains, utilizing preventative care is key for keeping quartz pristine:

  • Wipe up spills immediately to avoid prolonged exposure.
  • Use coasters under cups and pots to prevent transfer of rust.
  • Seal and maintain stone surfaces with a quartz-safe sealant.
  • Avoid excessive humidity around quartz with proper ventilation.
  • Clean quartz regularly with a pH-neutral stone cleaner.
  • Consider attaching a water filtration system to counter hard water stains.

Can You Use Scrubbing Pads on Quartz?

Soft nylon scrub pads are generally safe to use on quartz for regular cleaning. However, avoid aggressive scouring pads, steel wool, and abrasive powders as they can scratch and dull the surface over time. Test any new cleaning pads first on an inconspicuous area. Let the cleaning solutions do most of the work rather than excessive scouring.

When to Call a Professional for Quartz Rust Removal

For stubborn rust stains or etching that do not respond to normal cleaning methods, consider calling a professional stone restoration company. They have access to more powerful rust removal solutions and polishing equipment to renew the quartz finish. However, these strong chemicals can only be used sparingly. Avoid damage by hiring a reputable professional with expertise in quartz care.


Though durable, quartz countertops can develop unsightly rust stains from exposure to metals, spills, hard water, and humidity. Thankfully, safe household solutions like baking soda, vinegar, lime juice, hydrogen peroxide, and oxalic acid can effectively remove rust without harming quartz. Along with prompt stain removal, prevention is key through careful use of coasters and sealants. With the proper care, beautiful quartz countertops can stay free of rust for years. Handle any stains promptly for best results. Seek professional help for significant etching or difficult stains that don’t respond to DIY methods.
