Did a playground for the city parks & rec. dept. This is the first time I've encountered material like this. The fabric for the shelters is pretty loosely woven and not completely water tight. Its meant to be more of a sun-shade than a water proof covering. The algae was on all sides of the fabric too, so the inside and the outside had to be washed and rinsed too. Rinse had no "run-down effect" either, every inch of fabric had to be rinsed with light pressure, otherwise I was left with striped patterns.
The fabric did clean up with a 15-20% SH concentration. Just surfactant/detergent and SH and water. No funky additives. Soft washed the whole playground.
