Algy dosn't like alkalines...use a detergent like washing soda or a mild
caustic soda solution, either water it onto a damp[1] surface with a
watering can or spray it on and leave it for a while (45 mins+) then scrub
with a stiff brush and finally rinse with the hosepipe.


[1] if the patio is very dry, the solution will not penetrate as well, just
give it all a blast over with the hosepipe twenty mins before you apply the
soda.
