Best way to clean mildew off of gutters and siding

We lease a home. This is a cosmetic issue but, this mildew issue is just nasty and runs across most of the front of the house. I don't mind tackling this but, it is A LOT of mildew and I would love it if there was some not hideously expensive ... or toxic ... way of somewhat easily cleaning these up without it turning into a life's work type project? I'm open to any and all suggestions! TIA!
PS ... not sure if they are vinyl or metal gutters ... the house is less than 15 years old ... if that's a clue.

    There is a product called wet-and-forget which is a non chlorine based product safe for all surfaces available in Home Improvement stores.

    Great, thanks! I have seen this and wasn't sure if it worked as well as they stated! Good to know it does! :)

    Have you thought to ask the landord to have this taken care of? It is his investment.

    wet and forget! we used to painfully power wash our whole house once a year. found wet N forget at Lowe's and will never go back to power washing. put the concentrate into a pump sprayer according to directions and a rain shower will take care of the rest for you.

    JoMaxx or bleach is the only thing that has ever worked for me... Just remember, if you use anything else you are going to have to scrub. The ones recommended in previous comments are a total waste of money unless you scrub. Plus, all the others do not kill the mildew so you will be cleaning again very shortly even if you succeed in scrubbing it off because it will grow right back.

    My problem is that my gutters are about 40' high in the rear of my house. That is where it needs it the most. So, how do i apply anything from the ground up that high?
