Stucco streaks and rust

What would you use to clean these chimneys. They have a lot of them and they did change the tops so they will not streak anymore. Roofs are not very easy to walk.

Yea. (Extremely)Diluted gutter cleaner will work. It probably won't remove it 100%, but it'll look a billion times better.

I can usually get off the black streaks with a roof wash, and the rust stains with an acid. Sometimes a little agitation goes a long way with these chimneys.

Hey Brian. We'd use roof mix for the streaks as Joe mentioned, and ox for the rust. We'd walk the roof to treat the chimney with mandatory cougar paws.

We would Flood the roof with water if we aren't cleaning the roofs. Treat the streaks w a roof mix, heavy rinsing. The then the rust stains with F9.
