At the pet store you can buy ';Poop Off'; in the bird section. It works really well and some come with dispensers to make the job even easier.

My experience is that warm sudsy water and a scrubbing brush are enough, if you are patient. If the droppings are dry and hard, let them soak for a while, or wait until they have been rained on. Remove them gently layer by layer rather than scrubbing so hard you damage the surface. Clean up fairly promptly/regularly, because the lime in bird droppings can affect some surfaces.
just use a pressure washer
