Orange Stains on Garage Door?

I have what appears to be orange spots and run marks on the outside of my garage door at the top. I thought it was rust but it is not coming out where the nails and screws are. My garage door is white and just barely 2 years old. It goes all the way across the top and has run lines about 12 inches long and runs all the way down on both edges.

Has anyone ever encountered this problem or know what it is and how to remove it? So far, I have tried ammonia, Awesome, CLR, hydrogen peroxide, Clorox Cleanup and Windex. It seems to be cleaning the garage door but the spots and runs aren't budging!
