Tip #2: Be Sure Sprinklers Don’t Overspray Windows

If sprinklers are wetting your windows, you can be sure they are leaving behind hard water mineral deposits. Tap water is often high in calcium and other minerals that become etched into the porous surface of glass.

By making sure your sprinkler system is properly adjusted, along with being careful to not spray windows when watering, you can easily avoid this hard water buildup.
