Mildew on white aluminum pool enclosure

Any ideas would be greatly appreciated on removing green mildew from the white ribs of our North-facing pool cage without having to build a scaffold over the pool. Chlorine and water works on the part around the pool that we can reach with the pressure washer but there is not enough pressure not the center 50% of the pool If trying to shoot the pressure washer while standing on the perimeter of the pool.
