I just cleaned a marble paver patio. It was pretty clean to begin with but most of it is under a deck and sees no sun. There were a few parts where it looked like algae was growing. I got most of it off but as you can see in the photo, there is still a little green staining. Is that a stain from the algea and how do i remove it? I did use some bleach, but that seemed to do nothing.
