How to Clean Water Spots Off Quartz Countertops

Quartz countertops are popular in many homes due to their durability, aesthetics, and low maintenance. However, like any surface, quartz can develop stubborn stains over time, including water spots and mineral deposits from water. Thankfully, there are many methods to clean water spots off quartz effectively. With a little time and elbow grease, you can restore the beautiful, flawless look of your quartz countertops.

What Causes Water Spots on Quartz?

Water spots and hard water stains form when droplets of water dry and leave behind mineral deposits on the surface. The minerals in your tap water, such as calcium, magnesium, and silica, are the culprits.

As the water evaporates, these minerals are left on the surface. Over time, the buildup accumulates, leaving behind those unsightly spots and stains. Areas near sinks and faucets tend to develop more water spots because of frequent water exposure.

How to Remove Water Spots From Quartz Countertops

Removing water spots from quartz requires gently abrasive cleaning methods. More stubborn stains may need specialized stone cleaners that dissolve the mineral deposits. With the right techniques and products, you can banish water spots from quartz.

Supplies Needed

  • Microfiber cloths
  • Soft scrub brush or sponge
  • pH-neutral stone cleaner or mild dish soap
  • Clean water
  • “00” grade steel wool
  • Plastic scraper (optional)
  • Granite polishing powder (optional)

Step-by-Step Guide

Follow these steps to clean water spots off your quartz countertops:

Step 1: Dust and Wipe the Surface

Dust the countertop with a microfiber cloth to remove any loose debris. Wipe the surface down with a damp microfiber cloth to prepare the quartz for cleaning.

Step 2: Apply Stone Cleaner and Let Sit

Apply a pH-neutral stone cleaner designed for quartz and other engineered stones. Use a microfiber cloth to evenly distribute the cleaner over the water spots and residue.

Let the cleaner sit for 5-10 minutes. This allows time for the cleaner to penetrate and dissolve the mineral deposits. Avoid cleaners with acid ingredients which can etch quartz.

Step 3: Scrub and Rinse

Use a soft scrub brush, sponge, or microfiber cloth to gently scrub the water spots, working the stone cleaner over the stains. Apply light pressure as you scrub but avoid aggressive scouring.

Rinse the surface thoroughly with clean water to remove all cleaner residue. Wipe dry with microfiber cloths.

Step 4: Inspect and Repeat if Needed

Inspect the quartz to see if the water spots have lifted after scrubbing and rinsing. For stubborn stains that remain, repeat steps 2-3 focusing on problem areas.

Step 5: Use Steel Wool for Heavy Stains

For lingering hard water stains that resist stone cleaner, use “00” grade steel wool to gently scrub the spots away. Apply light pressure and rub in a circular motion.

Rinse and dry the surface when finished scrubbing. The fine steel wool fibers safely remove stuck-on mineral deposits without scratching quartz.

Step 6: Polish Away Cloudiness

After heavy-duty cleaning, quartz may appear cloudy or etched. Use a quartz-safe polishing powder designed for engineered stone and buff the surface with a microfiber cloth. This restores clarity and shine.

Rinse polishing powder off thoroughly and wipe dry. Avoid using polishing powders containing abrasives that could scratch quartz.

And that’s it! With these steps, you can banish pesky water spots from your quartz countertops. Be patient during the cleaning process and keepsurfaces damp to avoid mineral streaks. With routine care, you can keep quartz gleaming like new.

Tips for Preventing Water Spots on Quartz

Once you’ve successfully cleaned water stains from your quartz countertops, keep them pristine with these preventive measures:

  • Wipe up spills immediately to prevent buildup
  • Avoid letting water pool near faucets and sinks
  • Use coasters under cups and glasses
  • Apply a quartz sealer to protect from stains
  • Clean quartz regularly with a pH-neutral cleaner
  • Run water briefly before wetting sponges to rinse away minerals
  • Dry surfaces thoroughly after cleaning and dishwashing
  • Consider water softeners or filters to reduce minerals

With diligent care and regular cleaning, you can minimize water spots on quartz countertops. But if stains eventually build up, use the effective techniques above to restore their beauty.

FAQs About Removing Water Spots from Quartz

How do you get rid of baked-on water stains on quartz?

For stubborn, baked-on water spots, use a plastic scraper to gently loosen the stains before scrubbing with a pH-neutral stone cleaner. Steel wool also helps scrub away the toughest hard water marks.

What is the best homemade cleaner for quartz countertops?

Make an effective DIY quartz cleaner by combining distilled white vinegar and water in a 1:3 ratio. For example, mix 1 cup vinegar and 3 cups water. Use a soft cloth to wipe the solution over the surface. Rinse thoroughly. Avoid acidic cleaners long-term which can damage sealers.

Can I use baking soda to clean quartz countertops?

Yes, baking soda can be used to gently clean quartz and remove stains. Make a paste with 3 parts baking soda and 1 part water. Rub the paste onto stains with a soft sponge or cloth using light pressure. Avoid other abrasive powders which could scratch quartz.

What removes hard water stains from quartz?

Hard water stains respond best to pH-neutral stone cleaners or alkaline solutions. Mineral deposits dissolve with gentle scrubbing using a cleaner containing potassium phosphate. For tough stains, “00” grade steel wool helps scrub away the mineral buildup without damaging quartz.

How do you polish quartz countertops after cleaning?

Use a specially formulated quartz polishing powder to restore sheen and shine after heavy duty cleaning. Apply the powder to a soft cloth and gently buff the countertop in a circular motion. Avoid powdered abrasives like Comet or Bar Keeper’s Friend which can scratch quartz.

Does Windex remove water spots from quartz?

No, Windex is ineffective for removing dried water spots or hard water stains from quartz countertops. The ammonia in Windex cannot dissolve mineral deposits. Use a quartz-safe cleaner instead. However, Windex can be used for routine quartz cleaning between deep cleans.


Water spots and mineral deposits can accumulate on quartz countertops over time, marring their appearance. Thankfully, with the proper supplies and techniques, you can remove the stains and restore quartz to its original beauty.

Be sure to use non-abrasive cleaners designed for engineered stone. Mild dish soap also works when mixed with warm water. Clean gently, but scrub persistently. For really stubborn stains, reach for steel wool to erase the marks.

With routine maintenance and careful cleaning habits, you can prevent water spots from forming on quartz surfaces. Keep counters dry, wipe spills quickly, and rinse minerals off before they have a chance to deposit. Your quartz countertops will maintain their flawless, glossy look for years to come.
