I don't have a pressure washer, just a hose pipe. I read the most effective can be bleach but I am worried about killing the garden. Do you just leave the bleach to evaporate? I don't really want to hose it off because the only place it can go is onto my lawn.
Another option is white wine vinegar and Bicarbonate of soda an a thick bristled brush...I have all these things:). Would this mixture damage my lawn as well if i hosed it off onto my lawn?
Thanks in advance
