How to Make Quartz Countertop White Again

Clean with Baking Soda

Baking soda is a mild abrasive that can help scrub away stains and discoloration. Make a paste of baking soda and water and use a soft cloth or sponge to gently rub it onto the stained areas of the countertop. Let it sit for a few minutes before rinsing clean. The baking soda will help lift dirt and oils that have settled into the pores of the quartz. Repeat as needed until you achieve the original white color.

Use Hydrogen Peroxide

Hydrogen peroxide is another good cleaning agent for whitening quartz. Mix equal parts hydrogen peroxide and warm water and use a soft rag to apply it to the countertop. Allow it to sit for 5-10 minutes before scrubbing with a soft brush and rinsing clean. Be careful not to let the hydrogen peroxide sit too long, as it can damage the finish. Hydrogen peroxide works to brighten the quartz and remove stubborn stains.

Try a Bleaching Product

There are several commercial cleaners made specifically for whitening and brightening quartz countertops. Look for products that contain ingredients like sodium percarbonate or hydrogen peroxide. Carefully read and follow label directions, as leaving a bleaching product on too long can damage the quartz. Apply the product, let it sit for the recommended time, scrub with a soft cloth or brush, and rinse thoroughly. Only use these types of cleaners occasionally, as frequent use can wear away the finish.

Use a Polishing Compound

For a deep clean, use a specially formulated quartz polishing compound. These are abrasive pastes designed to remove etching and scratches. Apply a small amount to a soft cloth and rub onto stained areas using circular motions. Some pressure may be needed to remove stubborn marks. Thoroughly rinse the countertop when finished polishing. Be cautious not to over-polish, which can lead to a glossy look. Use sparingly on matte finish quartz.

Re-seal the Surface

Re-sealing the quartz countertop every 1-2 years will help protect the finish and prevent stains. Use a penetrating sealer made for quartz and apply according to product instructions. Re-sealing fills in pores, creating a barrier against dirt, oils, and liquids that can discolor the surface. Make sure to thoroughly prep and clean the countertop before applying the sealer.

Prevent Future Discoloration

To keep your quartz counters looking freshly white, try these maintenance tips:

  • Wipe up spills immediately to prevent staining
  • Use coasters under glasses and bottles
  • Clean with a mild soap and soft cloth regularly
  • Avoid abrasive cleansers or scouring pads
  • Don’t place hot pans directly on the quartz
  • Re-seal the surface every 1-2 years
  • Avoid exposing the quartz to harsh chemicals

With a little routine care and some deep cleaning methods as needed, you can keep your quartz countertops looking like new. The right products and techniques can remove stains and restore the bright white color you originally fell in love with. Be patient and treat the whole surface evenly for best results. With quartz, it is possible to get back that just-installed appearance.

Frequently Asked Questions

How can I prevent my quartz from yellowing in the first place?

Using sealers, coasters under drinks, and prompt cleanup of spills can help prevent yellowing. Avoid exposing quartz to harsh chemicals. Also, limit placement of hot pans directly on the surface.

What kind of cloth should I use to clean quartz?

Use soft, non-abrasive cloths like microfiber. Avoid scrubbing with rough sponges or paper towels. This can create tiny scratches that affect the look.

Is it okay to use bleach on my quartz countertop?

Bleach is too harsh for quartz and can damage the surface. Specialty quartz cleaners with brighteners or hydrogen peroxide are safer options. Never mix bleach and ammonia, as this creates a toxic gas.

Can vinegar whiten a yellowed quartz countertop?

Vinegar is too mild to effectively remove deep stains from quartz. You need a more powerful cleaning agent like baking soda, hydrogen peroxide, or a specialty quartz polish.

Is there a homemade solution I can use to brighten my countertop?

Making a paste of baking soda and water can help lift some discoloration without the need for commercial cleaners. Just rub into stained areas, let sit briefly, then scrub and rinse.

How often should I polish my quartz countertops?

Only polish your quartz counters occasionally, 1-2 times per year. Frequent polishing can result in a shinier surface than intended. Use a specially formulated quartz polish and avoid over-polishing.


Quartz countertops are meant to stay looking clean and bright white for years. But when stains and yellowing occur, don’t replace the whole counter just yet. With a little quartz cleaning know-how, you can often remove discoloration and restore the white Quartz finish. Gentle abrasives like baking soda, mild bleach, and polishing pastes allow you to safely deep clean without damaging the quartz surface. Maintain results by promptly wiping spills, avoiding direct heat exposure, and re-sealing every 1-2 years. With proper care and occasional whitening cleanings, your beautiful quartz counters can stay looking their best for many years before needing a professional resurfacing.
