How to Remove Water Spots from Quartz Countertops

Water spots on quartz countertops can be unsightly and frustrating to deal with. However, with a bit of effort and the right cleaning solutions, you can remove them and restore the beautiful, glossy surface of your countertops. Here is a comprehensive guide on how to effectively remove water spots from quartz.

What Causes Water Spots on Quartz?

Quartz countertops are made from engineered stone composed of natural quartz crystals combined with resins and pigments. When water sits on the surface, minerals in the water evaporate and leave behind mineral deposits that etch into the surface, causing white marks known as water spots.

Hard water, which contains a higher concentration of minerals like calcium and magnesium, is more likely to cause water spots. Other contributors include:

  • Letting water air dry instead of wiping it up
  • Spills and condensation from household items like houseplants, coffee makers, etc.
  • Cleaning with harsh chemicals that degrade the protective sealant

Removing Light Water Spots from Quartz

If the water spots on your quartz counters are light or just beginning to form, you may be able to remove them with a gentle cleaner and soft cloth:

Step 1: Prepare the Surface

Clear everything off the countertop you’ll be cleaning to give you ample working room. Remove any dirt or debris around the water spots.

Step 2: Mix a Mild Cleaning Solution

Make a cleaning solution by mixing a couple drops of dish soap with warm water in a spray bottle. Avoidusing anything too harsh or abrasive.

Step 3: Spray and Wipe

Liberally spray the solution directly onto the water spots. Let it sit for a minute or two. Then take a soft, damp microfiber cloth and wipe in a circular motion. Rinse with clean water and dry thoroughly.

This method should lift light water spotting. For stubborn spots, move onto the next solutions.

Removing Moderate Water Spots from Quartz

For more pronounced water spotting, you’ll need to pull out the big guns. The following solutions have the power to dissolve the mineral deposits causing the spots:

Baking Soda Paste

Make a paste by sprinkling baking soda on the dampened spots and adding just enough water to form a spreadable consistency. Allow it to sit for 5-10 minutes, then scrub gently with a soft cloth or sponge. Rinse and wipe dry with a microfiber towel.


Full strength white vinegar will help dissolve water deposits. Dip a cloth in undiluted vinegar and place it on the spots for several minutes. Scrub and rinse away. Straight vinegar can dull the shine of quartz, so polish with a quartz cleaner afterward.

Hydrogen Peroxide

Hydrogen peroxide is another mild acid that breaks down mineral buildup. Apply it directly to the water marks and let bubble for a few minutes before scrubbing and rinsing.


Ammonia is effective at removing water spots on quartz. Dilute some household ammonia with an equal part water in a spray bottle. Spritz it on and let it sit for 5 minutes before wiping away.

Always spot test chemicals in an inconspicuous area first to ensure they don’t damage the quartz.

Eliminating Stubborn Water Stains on Quartz

For water spots that resist gentle cleaners, it’s time to bring in the big guns – polishing powders and compounds. These mildly abrasive cleaners safely remove all signs of etching on quartz:

Baking Soda & Water Paste

Make a paste with baking soda and water, spreading it over the stained area. Let it dry completely until it forms a white crust. Wipe it off using a damp microfiber cloth with a bit of pressure. Rinse thoroughly.

Soft Scrub & Water Paste

Instead of baking soda, you can mix Soft Scrub with water to make an effective abrasive paste. Follow the same method as above.

Bar Keeper’s Friend

This powder cleanser contains oxalic acid and abrasives that polish away the toughest water stains. Make a paste, apply to the spots, allow it to sit for 5-10 minutes, then scrub. Rinse thoroughly afterward.

Polishing Compound

As a last resort, use a polishing compound made specifically for quartz countertops. Apply with a buffing pad and buff the spots in circular motions. This will remove the top layer of the quartz, so use sparingly.

Always avoid abrasive cleaning pads, steel wool, and alkaline chemicals like bleach or ammonia, as these can damage the quartz surface.

Preventing Water Spots on Quartz

Prevention is key to keeping your quartz gleaming and spot-free for the long run:

  • Wipe up spills and water splashes immediately with a dry cloth
  • Use coasters under glasses and bottles
  • Seal quartz every 6-12 months with a stone sealer
  • Avoid exposing quartz to harsh cleaners or chemicals
  • Use cutting boards instead of slicing directly on the counter
  • Clean quartz regularly with a pH-neutral quartz cleaner
