How to Get Water Spots Off of Quartz Countertops


Quartz countertops are an increasingly popular choice for kitchens and bathrooms due to their durability, aesthetics, and low maintenance. However, like any surface, quartz can be susceptible to water spots and mineral deposits from water and cleaning products. The good news is that with the right techniques and products, these spots can be removed to restore the beauty of your quartz.

What Causes Water Spots on Quartz?

Water spots and mineral deposits occur when minerals in water are left to dry on the surface. Quartz is non-porous, so water cannot penetrate into the material, but instead evaporates on the surface. As it dries, the minerals are left behind, leaving unsightly spots and residue.

Common culprits that can leave water spots include:

  • Hard water – Water with high mineral content like calcium and magnesium. These minerals get deposited on the surface when the water evaporates.
  • Cleaners and soaps – Many cleaners and soaps contain additives that can bind to minerals in the water. As the water dries, these compounds leave residue on the quartz.
  • Food and beverages – Acids and sugars in items like lemon juice, vinegar, coffee, tea, and wine provide material that allow mineral deposits to cling when the liquid dries.

How to Remove Water Spots from Quartz

While quartz is durable, you want to use the gentlest method possible to remove water spots and minimize unnecessary wear and tear. Here are effective solutions to safely clean quartz without damaging the surface:

Use a Soft Sponge and Mild Soap

For light water spotting, often a soft sponge and diluted mild soap is effective. Apply a small amount of dish soap like Dawn mixed with warm water to the area. Gently scrub with a soft sponge or microfiber cloth using light pressure. Rinse and dry thoroughly afterwards. Avoid abrasive sponges or scrubbing aggressively.

Try a 50/50 Vinegar and Water Solution

Due to the acetic acid, white vinegar can help break apart mineral deposits and remove water spots. Mix equal parts white vinegar and warm water. Dip a soft cloth or sponge in the solution and wring out excess liquid. Wipe down the affected areas, allowing the solution to sit for 2-3 minutes. Rinse thoroughly with clean water and dry the surface completely.

Use Rubbing Alcohol

For stubborn water stains, rub a small amount of isopropyl alcohol directly on the spots using a microfiber cloth or paper towel. Let sit for 2-3 minutes before rinsing and drying the area thoroughly. The alcohol will help break up mineral deposits. Be sure to spot test first.

Try a Quartz Cleaner and Conditioner

Look for a specialty quartz cleaner made to remove water spots and condition the surface. Carefully follow the product directions. Many can be applied directly to the affected area, left to sit, and then rinsed off. The cleaners contain ingredients designed to dissolve mineral deposits. Using an occasional quartz conditioner can help prevent buildup of water spots.

Use a Poultice to Draw Out Stains

For really stubborn spots that won’t budge, make a poultice using baking soda and hydrogen peroxide. Form into a paste and apply to the stain, allowing it to sit for 5 minutes covered with plastic wrap. The poultice will help draw out the minerals. Rinse and dry well. A powdered stain remover can also be used to make the poultice.

Steam Clean the Surface

If needed for widespread water staining, use a handheld steam cleaner to gently melt and loosen any deposits. Focus steam on stained areas, then wipe away released deposits with a soft cloth. Make sure to wipe in direction of patterns/grain and rinse.

Tips for Preventing Water Spots on Quartz

Once you’ve successfully removed water spots, you can take steps to prevent new ones from forming:

  • Wipe up spills immediately to prevent evaporation and deposit buildup.
  • Thoroughly rinse and dry quartz after cleaning, especially with harsher cleaners.
  • Use a squeegee on the countertop after it gets wet to prevent water drying and leaving spots.
  • Consider using a sealant made specifically for quartz about once a year to protect from staining.
  • Avoid using acidic or abrasive cleaners which can etch or damage quartz over time.
  • Use trivets and coasters under hot pans, cups, or anything that could transfer moisture.
  • Have your water tested and install a water softener if you have excessive mineral content.

With proper care and by addressing water spots promptly, you can keep your quartz counters gorgeous and spot-free for years to come.

Frequently Asked Questions

What is the fastest way to get water spots off quartz?

For light spotting, wipe with a diluted mild detergent using a soft sponge or cloth. For stubborn stains, try rubbing alcohol or a vinegar/water solution. Aggressive scrubbing can damage the surface.

Does vinegar remove hard water stains from quartz?

Yes, white vinegar’s acetic acid helps dissolve mineral deposits left by hard water. Mix equal parts vinegar and warm water. Wipe on spots with a soft cloth, let sit 2-3 minutes, then rinse. Only use occasionally.

What removes dried water spots on quartz?

Rubbing alcohol or vinegar solutions can break down mineral deposits. Specialty quartz cleaners also work well by dissolving the dried minerals. For tough stains, make a baking soda and peroxide poultice to draw out deposits.

Can I use baking soda and water to clean quartz countertops?

A baking soda and water paste is too abrasive for quartz. For light cleaning, use diluted mild soap and water with a soft sponge or cloth. Baking soda can be used in a poultice with peroxide to gently lift stubborn stains.

Will Quartz stain if not sealed?

Quartz is non-porous, so it resists staining better than surfaces like granite or marble that need regular sealing. However, using a quartz-specific sealer about once a year can provide added protection.

Does Windex remove hard water stains from quartz?

No, Windex alone won’t effectively remove hard water stains as it lacks an ingredient like vinegar to dissolve mineral deposits. Use a quartz specialty cleaner or a 50/50 vinegar and water solution for best results.

Can I use a Magic Eraser on quartz countertops?

It’s not recommended as Magic Eraser sponges are a bit too abrasive for quartz. For stuck on stains, try a poultice instead to gently lift deposits. Use only soft sponges or cloths when cleaning quartz.

How do you polish water stains off quartz?

You don’t need to polish quartz to remove water spots. Gentle cleaning with vinegar, rubbing alcohol or a quartz cleaner will dissolve any deposits without polishing or buffing, which could damage the surface.


Water spots and mineral deposits from daily use and cleaning can detract from the sleek look of quartz countertops. Thankfully, using the right gentle cleaning solutions and techniques can safely and effectively remove the stains without damaging the quartz. Get into the habit of wiping up spills quickly, rinsing well after cleaning, and using trivets and coasters. With some periodic maintenance and TLC, you can keep your quartz counters spot-free and looking like new.
