Spray and Walk away sounds like what you are looking for. I use it on vinyl fence that gets no sun, green and black molds grow on it.
Spray this on and leave it. In a month our so the mold is gone. It does take patience, no immediate gratification, but it does work and the mold doesn't come back for years.
