I need to clean squirrel dung from a concrete block wall (interior) before I paint. I have tried pressure washing, greased lightning, Clorox and even pain thinner. Do you have a suggestion for removing this nasty stuff?

Try TSP, trisodium phosphate. This is a very strong cleaner and should take care of your problem. To help it work you could scrub the area(s) with a stiff push broom or scrub brush, something with a pole would work good.
