I just use bleach. It's diluted so much you can't smell it and it seems to work fine on the mold and dirt that accumulates in Florida. You have to soak the building or sidewalk first, then go back over it with high pressure. There's also Rust Out, or mix a solution of Iron Out. But bleach is the cheapest and usually the high pressure will be enough to clean whatever needs to be cleaned and you also want to be environmentally friendly.
