this is not Oxiclean it goes by the name "WaterSeal" and you get it at big box stores or lumber yards and it it put out by "Thompsons".
To clean outdoor surfaces, use concentrated oxygen powered cleaners, like this one, to remove dirt, mildew, algae, fungus. They are chlorine-free and biodegradable.
