Cleaning Block paving


Hi,
My block paving doesn't get much sunlight in winter resulting in it going green and mossy. I wondered if anyone could reccommend something to clean it with that wouldn't harm the plants. I normally use a jet wash but it is very time consuming. I have seen an attachment for a jet wash though that is for cleaning block paving, has anyone had any experience of this product and are they any good?
Thanks.

Chemical moss killers don't harm plants in my experience. I treated a concrete path about 5 years ago and the moss still hasn't grown back.
