How do I get fertilizer rust stains out of my concrete driveway?

I fertilized my yard late last year and made the mistake of leaving some fertilizer on my concrete driveway and sidewalk, and now I have these rust-looking stains. What would take that out? Keep in mind that I am the least handy person in the world so the simplier the better! Thanks :)

1. broom it off or hose it down and it'll be gone in a day or two.
2. just put bleach on it.
3. In a spray bottle mix a solution of 50% bleach and 50% water. Spray on the spots allow to soak a few minutes and hose off. Note - if your driveway is very dirty you will have noticibly cleaner spots and may have to do the whole thing. Test first. If you decide to do the whole thing you need a cheap pump up garden sprayer for your mixture. Good luck.
4. If it is indeed an iron rust compound you can get "Rust Off" at a hardware store. Works great.
