I have vinyl windows in my house. Some of the trim appears to have mold growing on it. I have long been under the impression that mold can’t grow on plastic. What exactly is going on here?

Dirt and grim builds up on the plastic and mold grows onto it. Wash it down.

Mold and mildew grow on plastic all the time. Or like **Si Amigo** said, the stuff that sticks to it.

Spray it with some Tilex or something. Works for my plastic shower curtain liner.
