    Get some bleach on it. After that it will take very little scrubbing.

    You can get Sodium hypochlorite which is also known as liquid chlorine, hypo or chloras from any good pool supplier. The stronger the concentrate the more it can be diluted so goes further. Mind you is lethal stuff to handle and use so wet everything down first like plants, grass etc it is likely to get on. It will also ruin your cloths. Best wear rubber chem gloves and eye protection too.

    I did one in the summer with washing up liquid, water and a deck scrubber. I rinsed with their hose pipe. It worked well and they were impressed with the result. I had to be careful what I used because they are keen gardeners.

    get wallwash from here its brilliant, put it diluted in a backpack/sprayer & rub over the area with your pole & leave, has to be a dry day though, any algae will be gone by next day & it rinses out of your kit with just a flush of cold water. a customer asked me to do his gable end with this stuff, I've been pushing these jobs ever since.
    its £13.40 for 5 ltrs but you don't need a lot
