Sometimes it seems that no matter what you do, you can't get them off. Usually, the sooner you get to them the better. If they have been on there a long time, they will be nearly impossible to remove.
I never go out of my way to remove shotgun fungus......I try, but I don'd kill myself over it. I explain to the customer when I do the estimate that some comes off, and some doesnt. To date, no one has given me a hard time about it.....they all seem to just accept it.
