How to Get Water Marks Off Quartz Countertops


Quartz countertops are an increasingly popular option for kitchen and bathroom remodeling projects due to their durability, low maintenance, and stylish appearance. However, like any surface, quartz can be susceptible to water marks and stains over time. Fortunately, there are several effective methods for removing water spots and restoring your quartz countertops’ original beauty.

In this comprehensive guide, we will discuss common causes of water marks on quartz, home remedies using mild cleaners and DIY poultices, professional services for stubborn stains, and most importantly – tips to prevent water damage in the first place. With proper care and maintenance, your quartz countertops can remain resilient and stain-free for years to come.

What Causes Water Stains on Quartz?

Before exploring removal techniques, it’s helpful to understand what leads to water spots in the first place. Here are some of the most common culprits:

Mineral Deposits

Hard water contains higher levels of minerals like calcium and magnesium. As water evaporates, these minerals are left behind, leaving unsightly spots and stains. Areas around sinks and faucets are particularly susceptible.

Standing Water

Allowing water to pool on the surface, such as from a leaky faucet or overflowing sink, gives minerals more time to etched into the quartz. Ring-shaped stains are a tell-tale sign of standing water damage.

Hot Pans and Appliances

Setting a steaming hot pan, pot, or appliance directly on the countertop can create water condensation that leads to marks. The heat intensifies the effect of minerals in the water.

Spills and Splashes

Acidic liquids like juice, vinegar, and wine can etch quartz surfaces upon contact. Dried-on soda and soap scum stains are also common with spills.

Cleaning Chemicals

Using harsh cleaners and scrubbing too aggressively can damage the quartz sealant over time. This causes the surface to become more vulnerable to etching.

Home Remedies for Removing Water Spots

For light water stain removal, several homemade solutions using gentle cleaners can be highly effective:

Baking Soda Paste

Baking soda is a natural abrasive that dissolves mineral deposits and draws out stains. Mix a paste of 3 parts baking soda to 1 part water and rub gently onto affected areas using a soft cloth or sponge. Allow to sit for 5 minutes before rinsing clean. Avoid scrubbing vigorously.


The acidic properties in vinegar work to dissolve water spots and hard water buildup. Use undiluted white vinegar and a non-abrasive sponge to rub stains. Rinse thoroughly with water afterward. Repeat if needed.

Hydrogen Peroxide

As a mild bleach, hydrogen peroxide can lift discoloration from water marks. Dip a soft cloth into the solution and blot stains for 2-3 minutes before wiping away. Be sure to dilute to avoid damaging the quartz sealant.

Dish Soap

For soap scum and oily stains, apply a few drops of dish soap and rub with a non-abrasive sponge. Let sit briefly before rinsing. The surfactants in the soap help break down grime. Avoid citrus-based formulas as they can damage quartz.

Microfiber Cloth

For light water spots, a microfiber cloth may be enough to remove the marks with pressure. Use a damp cloth and mild pressure in a circular motion. Check the stain to see if it transfers to the cloth.

DIY Quartz Poultice for Stubborn Stains

For tougher water stains that resist basic cleaning, a poultice can be an effective way to draw out deep-set marks. A poultice is a paste mixture that is applied directly to the stain for an extended period before being rinsed away.

To make a DIY quartz poultice:

  • Mix equal parts baking soda and hydrogen peroxide to form a spreadable paste.
  • Apply a 1/4 inch thick layer directly over the stain.
  • Cover with plastic wrap and seal the edges with painter’s tape.
  • Allow the mixture to sit for 24-48 hours.
  • Remove the plastic and rinse away the poultice thoroughly.
  • Check if the stain has lifted, repeating the process if needed.

The prolong contact and absorbing action of the poultice helps pull embedded stains out of the quartz pores for better cleaning results.

Professional Cleaning Services

For severe water damage or stains that resist DIY efforts, calling in professional stone restoration services may be warranted. Companies like Granite Gold and Miracle Method specialize in deep-cleaning stone and quartz:

Pressurized Steam

Truck-mounted steam cleaning units can blast away grime settled into pores under high heat and pressure. The steam helps sanitize while lifting stains.

Specialty Chemicals

Commerical-grade poultices, stripping agents, and etching removers can be used to treat what home remedies cannot. However, these harsh chemicals require expert handling to avoid damage.

Mechanical Scrubbing

Using a hand-held wand and soft brush attachment, technicians can precisely scrub affected areas to extract stains from the surface. This also avoids damaging the surrounding quartz.

Polishing and Resealing

To restore a uniform appearance after heavy staining, professionals may grind and re-polish the surface using specialty power tools. Reapplying a sealant protects from future water damage.

Tips to Prevent Water Marks on Quartz

While quartz is less prone to staining than natural stone, some basic maintenance habits can help avoid the need for stain removal in the first place:

  • Wipe up spills immediately to prevent liquids from dwelling on the surface
  • Run water for a few minutes before use to avoid mineral buildup around sinks
  • Use trivets and hot pads under hot pans and appliances
  • Clean with a quartz-safe soap and soft cloth or sponge
  • Reseal quartz every 1-2 years with a stone sealant product
  • Don’t let water pool from leaky fixtures; repair drips promptly
  • Increase humidity to reduce ring marks from condensation on cold surfaces
  • Rinse dishes, plants, and cleaning tools in the sink to avoid water drip marks
  • Blot wet items instead of letting them air dry on quartz surfaces

FAQ About Removing Water Stains from Quartz

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

For quick water spot removal, spray vinegar over the marks, let sit 2-3 minutes, and wipe with a soft, damp cloth. The acidic vinegar dissolves mineral deposits for fast action cleaning.

What are the best commercial cleaners for quartz stains?

Look for quartz-safe cleaners like Soft Scrub Gel, Method Daily Granite, or Seventh Generation Stone Cleaner. Avoid harsh bathroom cleaners, bleach, citrus, and abrasive scrubs. Read labels carefully.

Can I use Magic Eraser on quartz countertops?

Magic Erasers contain melamine foam which can scratch and damage quartz surfaces, so it’s best to avoid them. Use instead a non-scratching sponge with vinegar, baking soda, or dish soap.

How do you get dried soap scum off quartz?

For stubborn soap scum, let a damp microfiber cloth soaked in vinegar sit on the stain for a few minutes to soften it, then scrub gently with baking soda and rinse. Avoid abrasive scrubbers.

What is the best homemade quartz cleaner?

Mix together 1/4 cup of vinegar, 1 tbsp dish soap, and 2 cups warm water for an effective DIY quartz surface cleaner. Store in a spray bottle and shake before using. Rinse thoroughly after cleaning.

Can I use lemon juice to remove spots off quartz?

No, avoid citrus juices like lemon, lime, and orange on quartz. The low pH can damage the sealant and etch the surface over time. Use milder acids like diluted vinegar instead.


While quartz countertops are remarkably resilient, water mineral stains and marks can happen over time. Whether caused by hard water, hot pans, or spills, these spots detract from quartz’s desired clear, uniform appearance. But using the proper gentle cleaners, poultices, or professional services, these stains can be effectively removed and restored – keeping your countertops looking like new. Be sure to take preventative steps as well to minimize water damage in the high use kitchen and bathroom. With this guide’s advice, you can keep your beautiful quartz surfaces sparkling for years.
