The past two months have been very busy and I have rarely had my car out in the daylight. Being out during those few hours of sunlight we get this time of year, I noticed some rust-colored stains on the hood of my car (2011 Subaru Forester w/ Steel Grey Metallic paint). My car is kept in a garage, but I have to park on the street at work and frequently end up with leaves on my car throughout October and November. Could these stains be the result of leaves, or is there some other likely problem?
More importantly, what is the safest, most effective, and lowest effort way to remove these stains?
Here’s a picture of one taken without the flash:
