A quartz kitchen countertop is stain resistant but not stain proof, meaning liquid left too long can cause discoloration. Usually, the culprit is water from glasses and cooking. You can get rid of water stains by following these simple steps.
Step 1 - Make a Paste
To remove water stains, try making a paste of baking soda and water about the consistency of peanut butter.
Step 2 - Spread It
Use a sponge to gently work the mixture onto the water stain in a circular motion.
Step 3 - Spread Again
If this does not remove the stain, smear the same mixture directly over the stain. Cover the stain and mixture with plastic wrap to hold it in place. The heat trapped under the plastic will pull the stain out of the quartz.
Step 4 - Rinse
Leave it to sit overnight, and rinse in the morning.
By following these steps, you should be able to remove a water stain from your quartz counters.
