Cleaning Melamine

[Rance]

This building is covered with melamine panels. Below each joint there are black streaks. I tried a HW mix and lightened the streak but they were still there. I then tried a HOT roof mix and the streaks are still there. What else should I try?

Whatever you use for gutter streaks. I use Purple Power,..but F-13 or Castrol Super Clean or Simple Green,..etc...

Yep whatever you use for gutters and a brush and more than likely not all of those will come out completely. I've done several buildings like that and had to brush quite a bit.
