How do I clean mildew from the fabric of a bounce house?

We placed a bounce house (uncovered) in our shed sometime in November. I just pulled it out and apparently there was a leak in the shed (on top of the insane humidity) and the bounce house now has mold / mildew all over the fabric. Its very bright and the primary colors (red yellow and blue) How do I clean it really good and get all the spots off as well as stop it from growing back?
