Black streaks on aluminum siding
What can I use to get the black streaks off the aluminum TC siding? The black streak cleaner doesn't do anything. Any suggestions would be appreciated, thanks.

I have learned to live with them LOL. With my side graphics you can almost convince yourself that they blend in... OK, not really. But then I think about the work involved in removing them and I begin to think they look ok again.
Plus they always come back :)
