Self-Cleaning Windows

Inventor: PPG Industries

Wouldn't it be great if you never had to clean the windows in your house again? That's the promise of SunClean glass, which is lined with a transparent coating that breaks down dirt (and bird droppings) in the sun. When it rains or you spray the windows with a hose, the remaining residue is supposed to wash away without streaking. Available on a variety of window types for the home, the SunClean technology also works on insulated glass that blocks ultraviolet light.

Availability: In 2002
