My white (render) walls are destroyed in what is probablyred algae. Can anyone recommend a product I can use to remove it? How long doesit need to be left on for or does it need to be washed off within a certaintimeframe? I will power hose the whole house also, just want to get mytimelines right. I see a few threads onhere…

I see a few threads onhere about people using bleach – does this work well on Algae?

Thank you.
