Hard water contains minerals like calcium and magnesium, which leave behind stains on glass. The tricky part is that these minerals can be difficult to remove, turning stain removal into a challenge.

Remove Water Stains from Glass ­– a Few Strategies

There are various tips and tricks on how to remove water stains from glass, so feel free to try out various techniques in order to figure out what works best for you.

  • Using a good dishwashing soap (like Sunlight Dishwashing Liquid) can help to make sure that your glassware is clean and bright. Follow the directions on the label, and make sure to rinse your glasses before drying them.
  • One surprisingly simple way to tackle these water stains is to grab an old black and white newspaper, as the newsprint can reduce the minerals, making it possible to simply scrub the stains away. You can either use the newspaper in its dry state and wipe the glass with it, or soak the newspaper sheet in water before rubbing the glass.
  • White vinegar is another home remedy to remove hard water stains – it helps loosen the mineral deposits from the glass. You can even mix in some lemon juice, and then spray the solution on the glass.
  • Alternatively, use white vinegar mixed with a bit of baking soda, and apply this paste to the stained area of the glass, rinsing it off after a couple of minutes. If you are facing particularly stubborn stains, soak your glasses in a vinegar and hot water solution for a little while, and try gently scrubbing the stains away after.

Drying Glass the Right Way

Drying your glasses properly is another way to prevent some water stains and marks from appearing. It is important to use a towel which is clean and lint-free for the best possible results and to leave your glasses shiny and clear.
