Soot on exterior of chimney, not only on the cap, but rain washes it down to vertical pipe and the pan. Runoff from the pan carries it down to the stucco below and we can't get this stuff off! (Chimney or stucco)
Any ideas for how clean off the soot in the first place? Ideally I could clean the top of the vertical pipe and the pan, that would reduce the soot running off the stucco anyway.
Have talked to a contractor about this. The pan
has to be replaced anyway, and he will put in a new one with slightly larger overhang to help reduce the washing down onto the stucco. But I would like some advice about the soot and trying to prevent it or clean it up in the first place.
Contactor offered to paint the vertical pipe, that would give us a fresh start there, but should I ask for a specific kind of paint? If it is painted I need to be able to clean it off anyway?
I could ask the contractor to also replace the top cap, but I don't know how much this will help the soot / creosote problem. Cap is otherwise solid not rusted out and seems to keep the rain out.
Lastly we will repaint the stucco. But I need advice because I can see that the soot will just keep on washing down, eventually darkening the new coat of paint on the stucco. So I hope you can advise me on ways to clean this properly, or perhaps prevent soot from washing down from now on.

Thanks Rockford, but we have three chimneys, and even though this one has the worst soot
problem I think if we installed a cover on one we would go for the same treatment on all three.
In addition, there is the visual look of stucco to consider. Because we have stucco, and long surfaces/walls, we would have to stop the cover at some point, and have a boundary between the new chase cover and the stucco wall. The cover shown in your pics doesn't give me much confidence that the cover will blend in well to a stucco wall/chimney base.
