Sodium Percarbonate + Sodium Metasilicate as roofing/siding cleaner?
I would like to know if Sodium Percarbonate and Sodium Metasilicate combined would make a effective Roof and Siding cleaner. I'm seeking a safer and more yard and plant friendly alternative to bleach, which is the standard here in South Carolina. I use Sodium Percarbonate with great results on the decks I clean and finish now.
I need to remove/kill algae,fungus, mold and black streaks from roofs and siding; as I will be including this as a add on to my deck business. I have observed some yards after bleach has been used without care, it's not a pretty sight.
Any help/suggestion would be greatly appreciated!
