Cleaning Tips and Tricks

Follow these useful tips when cleaning white quartz countertops:

  • Act quickly to clean spills before they have a chance to set in and stain.
  • Always use a soft cloth or sponge when cleaning. Avoid abrasive pads or brushes that could scratch the surface.
  • Apply cleaners gently, never scrubbing aggressively on quartz.
  • Rinse surfaces thoroughly after cleaning to remove any residue.
  • Buff dry with a soft cloth to prevent water spots.
  • For food stains, try blotting with a damp cloth first. If needed, use an approved quartz cleaner.
  • For dried-on spills, allow 10-15 minutes for cleaners to penetrate before scrubbing.

Removing Common Stains

Here are tips for cleaning some typical stains on white quartz countertops:

Coffee and Tea Stains

  • Mix a paste of baking soda and peroxide and apply to the stain.
  • Let sit 5-10 minutes then scrub gently with a soft cloth or toothbrush.
  • Rinse thoroughly and wipe dry. The peroxide will help lift the stain.

Grease and Oil Stains

  • Apply a small amount of dishwashing liquid and scrub with a damp Scotch-Brite pad.

Red Wine, Berries, and Fruit Juice

  • Blot as much as possible immediately with an absorbent cloth.
  • Mix a mild detergent with warm water and scrub stain gently.
  • For stubborn stains, apply hydrogen peroxide and let sit before scrubbing and rinsing.

Dried Food and Sauces

  • Soak stained area with warm, soapy water for 5-10 minutes. This softens dried-on messes.
  • Gently scrub with a soft bristle toothbrush, getting into crevices.
  • Rinse thoroughly and wipe completely dry.

Hard Water Spots and Mineral Deposits

  • Wipe with a cloth dipped in full-strength white vinegar.
  • Let the vinegar sit for a few minutes before rinsing.
  • For tough deposits, make a paste with baking soda and vinegar. Let sit briefly before scrubbing and rinsing.

Mold and Mildew Stains

Preventing Future Stains

To help keep your white quartz counters looking their best:

  • Use coasters under glasses and wipe up spills immediately.
  • Clean counters frequently with a mild soap and water.
  • Avoid exposing quartz to strong chemicals like paint removers or oven cleaners.
  • Use trivets and hot pads when placing hot pans on the counter.
  • Reseal quartz every 6-12 months with an approved sealer.
  • Avoid using knives or abrasive pads directly on the counter. Use a cutting board.

When to Call a Professional

For stains that you are unable to remove with normal cleaning, consider calling in a professional quartz cleaner. They have access to more powerful cleaning solutions that can tackle the toughest stains without damaging the quartz.

Signs it’s time to call a pro include:

  • Stains that reappear shortly after cleaning
  • Permanent looking yellowing or discoloration
  • Unusual etching, pitting, or corrosive damage
  • Widespread stains covering a large surface area

Frequently Asked Questions

Is it ok to use bleach on quartz?

No, avoid using bleach or hydrogen peroxide at high concentrations as this can damage or discolor quartz over time. Always test cleaners on a small inconspicuous spot first.

What happens if I leave a stain too long?

The longer a stain sits, the harder it’ll be to remove. Dried, caked-on stains often require more aggressive scrubbing, which can damage the quartz. Act fast to clean spills before they have a chance to set in.

Can I use vinegar to clean quartz counters?

Yes, you can safely use vinegar to clean quartz. The mild acidity helps dissolve stains and buildup. Mix with water and wipe on, rinse thoroughly. Avoid soaking the surface.

How can I make my quartz counters shine?

For extra shine, mix a couple tablespoons of olive oil with lemon juice. Wipe this solution onto the quartz, allow to sit briefly, then wipe dry with a soft cloth. The acid and oil will buff the surface beautifully.

Should I reseal my quartz countertops?

It’s a good idea to reseal quartz every 6-12 months using a silicon-based sealer made for quartz. This helps prevent stains from setting into the microscopic pores of the surface.


While white quartz countertops are fairly stain-resistant, discoloration can happen over time. By acting quickly and using the proper cleaning methods, you can often remove stains and restore the bright white luster. For stubborn stains that resist normal cleaning, call on a professional quartz cleaner to renew the surface. With proper care, white quartz countertops will maintain their beauty for many years.
