We now have a concrete overlay finish on our driveway and lanai and I haven’t had much issue with the dark spots. But, I spray my landscape stone yearly with wet-n-forget to control mold buildup there. While I’m at at I will spray the gutter in front of my house to include the large storm drain opening. It is very effective at staying ahead of/removing (over time) the black buildup on the concrete. There is remarkable difference one side to the other on my street between treated and untreated.
