Hard water is a common cause of glass stains that can significantly alter the appeal of your glass windows. The stains usually appear in the form of white hazy spots on the surfaces of the glass. Unlike soft water, hard water contains a mix of mineral deposits like calcium and magnesium. Whenever the water comes into contact with glass, the moisture evaporates after some time but, the mineral deposits are left on the surfaces.

It is these minerals that cause water spots on glass. If they are allowed to accumulate on the glass for a long period of time, there are higher chances the glass will soon start to deteriorate. The mineral deposits that cause water marks on glass are alkali, which could be harmful on your windows. In fact, even just small water spots on your glass windows can make them look dirty and old.

Generally, there are many ways to remove water spots from glass windows. However, not all can work for you. The approaches may also vary based on the type of glass on your windows among other factors. Nevertheless, it is still important that you find a suitable way of removing the water stains from your windows before they cause bigger issues. The following are common ways to remove water spots from your glass windows.

Vinegar solution

Plain white distilled vinegar is the best for removing water spots from glass. However, it must be mixed with fresh water. While it is usually recommended to mix equal amounts of water with vinegar, you may want a high concentration of vinegar if the water spots are severe. To remove the water spots, spray the solution on the surface of the glass and let it soak for a few minutes then gently scrub the surfaces with a towel dipped in the same solution. Repeat the process until the spots are gone before rinsing. After the cleaning, make sure the glass is thoroughly dried so that the spots do not get the chance to form again.


This is also a common remedy for water spots on glass windows. Toothpaste is made to fight build-up and can effectively help you remove water stains from your glass windows. For ease of use, it is advisable to add a little water to the toothpaste. After preparing the surfaces, apply the paste then; wait for a few minutes so it is soaked up by the glass. Using a sponge, brush or towel, rub the paste gentle over the areas with the spots. Rinse the surfaces with fresh water and dry the surfaces properly using a clean towel.
