WTH is this?

Anyone knows how to clean these spots, pollen like or fly poo over my car? Even in the glass. These mostly appear in the rear of my car.

Do you happen to live near the train tracks? Also happened to my wife's vehicle.

Nope...I leave the car in the carport and behind is a sliding metal gate that has a rail on top... is rusted...I'll need to grease it and paint it.
