Hi Folks,

I would like to clean a build up of moss off my patio area, I have a
power-washer to do the final clean but it has struggled in the past with
some of the larger build up of moss in some areas. Can anyone recommend any
of the cleaning agents that you water/brush on and leave to dry or are they
a much-of-a-muchness? I'm not bothered by whether it is 'organic' or
'chemical-free' or any of that nonsense, I just want something that works.

Cheers
