Powerwashing only with water invites the mold problem to come back sooner than later regardless of the stain/sealer.Looks good now but he'll be doing it again much sooner than he thinks.

I use the Jomax/Bleach combo a lot....but for anything stubborn or really black I use 12% sodium hypochlorite (liquid pool shock). Make a dilution of 60% water/40% hypochlorite and add 6oz per gallon of TSP . Magic.....just be careful of plants/vegetation.
