How to Get Water Stains Out of Quartz Countertops

Removing water stains from quartz countertops can seem daunting, but with a little patience and the right techniques, your countertops can look as good as new. Here are some helpful tips for getting rid of water spots and rings from quartz.

Why Quartz Countertops Stain

Quartz is an engineered stone made from crushed quartz crystals combined with resins and pigments. It is an incredibly durable and low-maintenance material, but it is not completely stain-proof.

Quartz countertops develop water stains for a couple of reasons:

  • The resin in quartz is porous and can absorb liquids. Over time, the moisture evaporates but leaves behind mineral deposits that cause stains.
  • Quartz lacks the glossy sealant that natural stone countertops have. Without this protective barrier, liquids can penetrate into the surface.
  • Chemicals and minerals in water react with the quartz, etching rings and spots into the material. Hard water is a common culprit.

Removing Light Water Stains from Quartz

If you notice light water marks on your quartz countertops, try these simple cleaning methods first:

Use a gentle cleaner. Spray the stained area with an all-purpose cleaner or quartz-safe cleaner. Let it sit for 5 minutes before wiping clean with a soft cloth. Avoid abrasive cleaners.

Try a baking soda paste. Make a paste with 3 parts baking soda and 1 part water. Gently rub it onto the stain with a soft cloth or sponge. Rinse thoroughly and wipe dry. Baking soda is a mild abrasive that can lift stains.

Use a 50/50 vinegar and water solution. Mix equal parts white vinegar and warm water. Dampen a cloth and lay it over the stain for 5-10 minutes. The acidic vinegar will help dissolve mineral deposits. Blot dry with a clean cloth.

Try lemon juice. Squirt fresh lemon juice onto the stain and let sit for a few minutes before wiping clean. The citric acid in lemons can cut through mineral buildup.

Use a magic eraser. Gently rub the stained area with a damp magic eraser sponge. These micro-abrasive sponges can lift many water marks without damaging the quartz.

Treating Stubborn Water Stains

For more stubborn stains that don’t budge, try these advanced tactics:

Make a poultice. Mix together baking soda and hydrogen peroxide to form a spreadable paste. Apply to the stain, cover with plastic wrap, and allow to sit overnight before rinsing. This can draw out deep set stains.

Use a quartz polish. Apply a small amount of quartz-safe polish to the stained area. Buff in circular motions with a soft cloth until the stain dissipates. Avoid wax or polishes containing dyes. Test on an inconspicuous spot first.

Try a steam cleaner. A handheld steamer used at the highest setting can help loosen stubborn stains. Pass slowly over the stain and wipe with a soft cloth. Check the manufacturer’s guides first.

Sand lightly with fine-grit sandpaper. Only as a last resort, you can gently sand the stain in the direction of the grain lines using 600-grit or higher sandpaper. This gently abrades the top layer of quartz to remove the stained area. Avoid over-sanding.

Consult a pro. For extremely stubborn stains or etching, consult a stone restoration professional. They have access to more powerful cleaning solutions and tools. This can restore the quartz’s appearance without replacing the countertop.

Preventing Water Stains on Quartz

The best way to deal with water stains on quartz is to prevent them in the first place:

  • Wipe up spills immediately to prevent moisture from seeping in.
  • Use coasters under glasses, vases, and other containers.
  • Avoid exposing quartz to chemicals like paint removers, oven cleaners, drain cleaners, etc.
  • Use a cutting board for food prep instead of cutting directly on the counter.
  • Apply a penetrating quartz sealer every 1-2 years for added protection.
  • Clean quartz regularly with a gentle, non-abrasive cleaner.

With proper care and prompt attention, water stains don’t stand a chance against quartz countertops. Follow these techniques to keep your quartz counters looking like new.

Frequently Asked Questions

Why do water stains appear on my quartz countertop?

Water stains form on quartz because it is porous and can absorb moisture. Minerals and chemicals in water react with the quartz, leaving behind a stained deposit when the moisture evaporates. Hard water causes the worst stains.

What is the best way to get water stains out of quartz?

For light stains, use a baking soda paste, vinegar, or quartz-safe cleaner. For stubborn stains, try a poultice, steam cleaner, magic eraser, or have a professional use a powerful cleaner. Take care not to damage the surface.

Can I use bleach to remove stains from quartz?

No, avoid using bleach or acidic cleaners like lime scale removers. They can discolor quartz and damage the finish. Stick to gentle, pH-neutral cleaners specifically formulated for quartz.

I sanded my quartz countertop – is this okay?

Light sanding with 600-grit or higher sandpaper can safely remove some stains as a last resort. Take care not to over-sand, which can damage the surface. Consult a professional if extensive sanding is needed.

How can I prevent future water stains on my quartz countertop?

Wipe up spills immediately before they set. Use coasters for glasses. Avoid exposing quartz to chemicals. Cut on a board instead of the counter. Apply a penetrating quartz sealer every 1-2 years.


Water stains on quartz counters occur when moisture seeps into the porous surface and leaves behind mineral deposits. With the proper cleaning techniques, these stubborn stains can often be removed. For best results, try baking soda, vinegar, steam, or calling in a professional cleaner. And be sure to take preventative steps like sealing and prompt spill cleanup to avoid stains in the first place. With some persistence and care, you can keep quartz counters spotless and looking brand new.
