What's the best way of removing algae etc, its all over a caravan

Pressure washer?

Sponge / bucket of soapy water / elbow grease?
Tried all three and it hasn't worked,
The algae is ingrained particulary in recessed areas, I thought a
spray type chemical would remove the algae rather than have to scrub
it off.
I've still got moss on some areas of the car which won't come off
either.


Oxalic acid wash. Some descalers are based on oxalic acid. If not
phosphoric acid - Lime Lite, but try a small area first.




Where would one get this stuff from?
