Water varies depending on where you live. In many areas of the United States, really hard water is the norm because this water simply has a higher mineral content, usually with calcium and magnesium. Water in these areas is treated and filtered to make it potable and drinkable, but the softening process doesn’t remove all the minerals that can impact your windows. 

When hard water begins to evaporate, it will leave the minerals behind that end up drying and hardening, creating spots and stains across your windows. At first, these water spots on the glass are not super noticeable, but as time goes on, they will begin to build up, and a white glaze will begin to appear. The sun will bake these spots into your window glass and will make them really difficult to remove. If left untreated, water spotting can permanently damage your windows, as glass is susceptible to corrosion being porous. 

If you live in an area with hard water, then you can attest to how frustrating it can be to try and achieve stain free windows.

The science of hard water and your windows

To truly understand how hard water stains and ruins your windows, you have to first look at the structure of your windows. While glass looks shiny and glassy, it isn’t as glassy as it appears. Glass contains different rivets and creases or hills and valleys, so it isn’t as smooth as it looks. 

These little divots in the glass let debris get trapped and the minerals in hard water do the same. Increased mineral deposits in the water get trapped in the glass, and once they dry, they create a layer of hardened grime.
