What is an effective method for removing dark stains on exterior walls?

Dark stains on exterior walls are a common issue, especially in damp or shaded environments. These stains can be caused by algae, mold, or debris from leaves and plants, and can significantly affect the appearance of the walls. Standard cleaning methods, such as scrubbing with water or mild cleaners, are often not sufficient to completely remove these stubborn discolorations. It is important to use a product specifically designed to penetrate deeply and effectively combat the stains, so the walls look clean and fresh again.
