Rust develops on metal objects when exposed to moisture for a prolonged period of time. Rust won't normally develop on plastic windows but it can transfer to the surface when it comes in contact with a rusty item. Removing the rust stain on your window is important as it can easily transfer to curtains, in addition to taking away from your window's appearance and functionality.
