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.
