sodium hypochlorite
ok .. sodium hypochlorite 5.5 is great on bleach but bleach dries in 3-4minutes on the surface and it takes 7 to kill mildew. Pressure washer will not kill mold or mildew. Bleach is very very hard on your wood. You need a good deck cleaner with surfactants as well as sodium hypochlorite. Always remember mold is like an iceburg. If you kill whats only on top with bleach you might regret it later when u put a sealer over it. The mold will grow through the sealer and you will want to blame the sealer but you did not kill all of the mold.
Just an FYI
