What to Use to Remove Water Spots from Quartz Countertop

Removing water spots from quartz countertops can seem daunting, but with the right techniques and products, it can be simple. Quartz is an engineered stone made from natural quartz particles bonded with resin – this makes it highly durable, but also prone to water spots if not properly sealed and maintained. Don’t worry – those pesky spots can be banished with a little knowledge and elbow grease.

Why Does Quartz Get Water Spots?

Quartz contains tiny pores where moisture can penetrate and leave behind mineral deposits when the water evaporates. This is what causes the unsightly spots and film. Quartz needs to be regularly re-sealed to prevent this, as sealants fill in the pores and create a protective barrier. Without proper sealing, the quartz is vulnerable to staining.

How to Remove Existing Water Spots

If spots have already developed, don’t panic. Here are some simple methods to remove water spots from quartz:

Baking Soda Paste

Baking soda is mildly abrasive so it can gently scour the stains without damaging the quartz. Mix baking soda with just enough water to form a spreadable paste. Apply it to the spots and let it sit for 5-10 minutes before scrubbing with a soft brush or sponge. Rinse well and dry completely.


The acidic nature of vinegar helps dissolve mineral deposits and etched spots. Mix equal parts vinegar and water in a spray bottle. Lightly spray the spots, let sit briefly, then scrub with a non-abrasive sponge or soft cloth. Rinse thoroughly. Straight vinegar can also be used for tougher stains – just rinse extremely well.

Hydrogen Peroxide

Hydrogen peroxide is another mild acid that can lift stains without harming quartz. Dip a soft cloth into 3% hydrogen peroxide and gently rub stained areas. Let it fizz for a few minutes before rinsing. Be sure to always spot test first, as prolonged exposure can damage some stone.

Glass Cleaner or Ammonia

Using a glass cleaner containing ammonia can help remove water spots on quartz. Spray directly onto the spots, let sit 1-2 minutes, then wipe clean with a soft cloth, using gentle circular motions. Avoid rubbing aggressively. Rinse surface thoroughly after cleaning.

Polishing Pads

For light surface etching or haziness, use a buffing pad designed for polishing quartz or other engineered stones. Rub the pad over affected areas using minimal pressure. This helps smooth the surface without damaging the protective sealant.

How to Prevent Water Spots on Quartz

Prevention is key to keeping quartz free of spots. Here are some tips:

  • Seal quartz every 1-2 years with a penetrating sealer formulated for engineered stone. This fills pores and creates a water-resistant barrier.
  • Immediately wipe up spills and splatters to prevent moisture from soaking in.
  • Use coasters under glasses and avoid placing hot pans directly on the quartz.
  • Regularly clean with a pH-neutral quartz cleaner. Avoid abrasive cleaners.
  • Consider applying a quartz polish monthly to protect the surface shine.
  • Reseal if water starts to pool and bead rather than sheet off the surface. This indicates the sealant is wearing off.

FAQs About Removing Water Spots from Quartz

Can I use bleach to remove spots from quartz?

No, bleach can discolor or even damage quartz surfaces. It’s best to avoid harsh chemicals and stick to gentler ingredients like vinegar, hydrogen peroxide, or ammonia-based glass cleaner. Always spot test a small area first.

What about using lemon juice?

Lemon juice offers a natural acidity that can help dissolve some water deposits. Dip half a lemon in baking soda, then gently rub onto spots. Let sit briefly before scrubbing and rinsing. The baking soda boosts the cleaning power. Only use this method occasionally.

Is there a commercial spot remover for quartz?

Yes, look for a product specifically formulated to treat water spots and stains on engineered stone. These often contain acids like phosphoric or glycolic acid. Follow instructions carefully and thoroughly rinse the quartz afterwards.

Can I use magic erasers on quartz?

Magic erasers have a mild abrasive quality, so take care when using them. Gently rub stained areas, applying minimal pressure. Avoid excessive scrubbing, as this could dull the surface over time. Only use on very limited spots, not for overall cleaning.

How do I know if I need to reseal my quartz?

Signs that quartz needs resealing include water pooling rather than beading up and rolling off, spots appearing where they didn’t before, and an inability to wipe up spills before they soak in. Every 1-2 years is a good rule of thumb for reapplication.


Water spots on quartz countertops happen, but they don’t have to be permanent. With the proper cleaning methods and regular sealing, you can keep your quartz pristine. Be sure to treat stains quickly before they have time to set into the stone. Consistent care will maintain the beauty and functionality of your quartz surfaces for years to come.
