Hard Water Stains

Can Hard Water Stains be Removed From Windows?

Do hard water stains keep you from having clean windows?Do hard water stains prevent you from having sparking clean windows?

Hard water stains are formed on your windows by water containing a high mineral content. As it  repeatedly lands on the window, the minerals etch themselves into the glass.

You would think that as the sunlight hits the window it would simply dry the water. It does dry it, but that’s not all it does.

It bakes the residue into the window, which is how the etching occurs. Since glass is porous, the etching process doesn’t take a long time. Adding to the problem,  as the sun continues to hit the window, the bonding and etching continues until it is nearly impossible to remove.

How can hard water stains be prevented?

Don't let water sprinkler spray your windowsI’m not sure that it can ever be totally prevented, but there is one thing you can do to minimize it: Avoid letting your sprinkler spray on your windows.

Not only does your sprinkler water contain the natural minerals, but it also contains chemicals that your city may add to the water.

Can the stains be removed?

Hard water stains can be removed, but first, here are the don’ts:

  • You should avoid trying random chemicals on your windows. Some can damage your windows beyond repair, which means they will need to be replaced.
  • Don’t use razor blades to scrape your windows. Unless you have been trained in the techniques of using razor blades on glass, you could easily scratch the windows and cut yourself as well. Thus, not fixing the problem, but adding to it.
