I have the same problem. Use a mixture of Bleach and water. This will remove most of the stains, but they will come back.

Not sure about black mildew but I use plain old white vinegar on green mildew. I keep some in a spray bottle out back.

a bleach solution will probably do it, but it will dry out surface to some degree.
