This was my first cleaning today, I did not use my fatboy because I don't have it together yet. I mixed the apple cider sauce in a small amount and applied it with a pump sprayer that I had. This was mainly just to test the mix.
The roof I did was half under a pine tree, I do beleive that there was no pine sap on the roof but green algae stuff and GM. The Gloeocapsa Magma come off but I'm still left with something else that I'm not sure what it is and how to remove it. Thanks for your help!
