I'm looking for something that can get rid of moss from slabs/small
stones
etc from the back garden. At the moment it's like a building site, and
there
are no plants or grass that can be killed by chemicals.
I will use a pressure washer where I can but looking for something that
can
be poured over large areas.
I once heard that dishwasher powder does this, anybody heard of this?


You might try posting to uk.rec.gardening. Very knowledgeable folk there
and generally quite friendly.
HTH
ps. I wouldn't mention the dishwasher powder!
