Getting green algae stains off brickwork

[Sinkingfeeling]

Has anyone got a recommended way of doing this? The front wall of our house is quite badly stained with algae, or maybe just from where the plant overgrowth has been.

A pressure washer if you've got one should do it.

Or scrubbing brush and water with washing up liquid in.

cure the damp, that's the most important thing, then it will die

on a wall is usually water spilling over a blocked or rusted gutter.
