Rain and spots on your windows

Does rain leave spots on your windows?

Many people believe that rain leaves streaks and spots on their windows, but that is not exactly the case. Rain on a dirty window collects the dust and muck already on the window and consequently leaves spots. However, rain on a clean window has less grime and dust to collect, so the spots are minimal or in some cases nonexistant.

If rain leaves major spots on your windows it may be time to call a professional window cleaner.
