i prefer a bleach mix, however simple green also works and a pressure washer. Pretty easy. If you want to range out of the box then do an acid wash.

Either way once it's gone here's the keys of it

get rid of downspouts onto concrete
seal the concrete (2 coats)

that's all you have to do it won't come back if you do it the right way
