How to Clean Quartz Countertops Stains

Quartz countertops are beautiful and durable, but like any surface they can get stained over time. Don’t worry – with the right products and techniques, you can get your quartz counters looking like new again. Here’s a comprehensive guide on how to clean quartz countertop stains.

What Causes Stains on Quartz Countertops?

Quartz is non-porous, so spills and stains don’t penetrate the surface. However, residues from spills can build up over time. Common culprits that can stain quartz include:

  • Oils and grease from cooking
  • Coffee and tea
  • Fruit juices
  • Vinegar, wine, and acidic foods
  • Dyes from highly pigmented foods like turmeric and berries
  • Hard water deposits
  • Metal marks from pots and pans

While quartz resists stains better than other countertop materials, prolonged exposure to staining agents can lead to stubborn spots and discoloration. But with the right cleaning methods, you can safely remove quartz countertop stains without damaging the surface.

How to Remove Common Stains from Quartz Countertops

For food, beverage and water stains:

  • Mix a paste of baking soda and water and apply it to the stain. Let it sit for 5-10 minutes before scrubbing with a soft brush or sponge. Rinse clean.
  • Make a cleaning paste with hydrogen peroxide and baking soda. Spread on the stain and let sit for up to an hour before scrubbing clean.
  • Use a non-abrasive cleaner formulated for stone surfaces. Spray on and wipe away.

For grease and oil stains:

  • Clean with a degreasing dish soap, concentrated detergent or all-purpose cleaner. Apply with a soft sponge or cloth and scrub gently.
  • Use an ammonia-based cleaner. Apply with a soft cloth, let it sit for 5 minutes before wiping clean.
  • Make a paste with baking soda and water. Spread on the greasy stain and let sit overnight. Scrub away in the morning.

For hard water stains:

  • Make a paste using lemon juice and baking soda. Apply to the stain and let sit for a few hours before scrubbing clean. The citric acid helps dissolve mineral deposits.
  • Use undiluted white vinegar. Soak a cloth and place it on the stain for 1-2 hours, then scrub away.
  • Use a hard water stain remover formulated for stone and quartz. Apply as directed and rinse.

For metal marks:

  • Immediately wipe the area with glass cleaner or ammonia. This prevents staining.
  • Make a paste with baking soda and water and gently scrub the marks away.
  • Use a poultice made with pH-neutral oxygen bleach, flour and water. Apply to the stain, cover with plastic wrap and allow to work overnight before scrubbing clean.

For dye stains:

  • Make a poultice using hydrogen peroxide and baking soda into a spreadable paste. Apply to the stain, allow to sit for 4-6 hours under plastic wrap, then scrub clean.
  • Use an oxygen bleach cleaner made for stone surfaces. Check the label and follow directions.
  • Try rubbing the stain gently with a Mr. Clean Magic Eraser. This can lift dye without damaging the quartz.

Helpful Tips for Cleaning Quartz Counters

  • Always use a mild cleaner specifically designed for quartz and stone. Avoid harsh chemicals.
  • Blot spills quickly to prevent staining. Don’t let liquids sit.
  • Scrub gently with a soft cloth, sponge or brush. Avoid abrasive pads.
  • For stubborn stains, let a poultice or cleaning paste sit for hours to lift the stain before scrubbing.
  • Thoroughly rinse and dry quartz after applying any cleaner to prevent streaks.
  • Reseal quartz countertops every 1-2 years with a penetrating quartz sealer to prevent stains.
