Algae is easy but efflorescence I steer clear of
Water staining? - like limescale do you mean?Thanks for your reply guys,
I like the idea of a vinegar application, think I'll try a test patch to see.
It might just be water staining, I've done quite a few sand & cement render cleans with some similar type staining but in much smaller areas.
A good 4% agitated hypo wash would do the trick
cheers
