cleaning gray film off exterior windows

judy warren

is there a good, non-abrasive product to clean a gray spotty film off the exterior surface of my large window?

Windows on Wash

What surfaces? Glass, frame, etc?

Is there a window screen on the window? If so, what material is it made of?

If the screen is aluminum, that gray film is usually oxidation from the aluminum and cleans off very easily.

If the spotting is in the painted surface, it is often mold and requires a bit more effort to get it off. In some cases, it is coming from behind the finished surface and is impossible to clean.
