Can anyone recommend something really good for cleaning flagstones?

I've tried the garden-centre algae killers, vinegar, strong
detergent, and I don't possess a power-washer and don't really want
to buy one just for this.-



Last winter I left a large unopened bag of compost lying flat on the
patio, when I moved it in the spring the slabs underneath were cleaned
to the original state, I've been trying to work out why so that I can
reproduce the effect over a large area.



The plastic killed off the weeds and prevented re-growth? A plastic coered
patio is unlikely to be a thing of beauty, though! ;-)
