Make sure you wet any bushs realy well before and after but if you get jomax it tells you how to mix it with bleach. I have washed alot of houses and if its realy realy bad i use pure bleach, wet sideing spray bleach let sit a few min then wash realy well. I use a back pack sprayer to spray bleach with and wash down with just a water hose, pressure washer gets water in bad places sometimes
