Hard water spots are caused by minerals like calcium and magnesium in your water. When a surface gets wet, the water evaporates but leaves the mineral deposits behind. Sprinklers, car washes, and showers can all cause hard water spots to form on glass. Chemically, these deposits are alkali, so they require an acid to remove them. Of course the best thing to do is prevention! But with a few household ingredients, you can remove and prevent further mineral deposits.
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.
- Fill a squirt bottle with half water and half vinegar. The best vinegar to use is plain white distilled vinegar, which is inexpensive and effective. A higher concentration of vinegar may be even more effective, so adjust the vinegar to water ratio based on the severity of the water spots.
- 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.
- Using a good dish-washing soap 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.
- Apply white toothpaste to the area. As strange as this may sound, toothpaste is made to remove build-up, so it works fairly well on hard water spots.
- Try an old black and white newspaper, as the newsprint can reduce the minerals, making it possible to 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.
- Use lemon juice instead of vinegar. Lemon juice has the same acidic properties as vinegar, and can be equally as effective. Fresh lemon usually works better than bottled lemon juice.
- Use an abrasive scrubber. An alternate approach to using an abrasive cleaner is to use an abrasive scrubber. The scrubber essentially works like very fine sandpaper to remove stains and build-up from the glass. Some popular abrasive scrubbers are steel wool, rough green scrub sponges, and a product known as a magic eraser, which is a very fine sponge.
