I have cleaned the render on four houses on a small estate using hypo with good results, they have had black steaks etc before cleaning.
Today I have been asked to do a gable end that is covered in the same streaks but a dark red colour.
Any body had a go at anything similar.
I'll get some pics tomorrow
