I have a 3000psi 2.8gpm w/downstream. My house is grey hardiplank with white wood trim. There is green algae on the hardiplank and almost all of the caulk on trim seams and trim itself is stained black with mold/mildew?? I want to wash it the right way and have been doing some reading on the site. I want to spray a mix on, let it sit and rinse it off. Is there a decent mix I can make using household chemicals, or am I wasting my time by not ordering the simple cherry and some pool chlorine? Is there a good basic mix using just household bleach and detergents? I've read a bunch of different ideas. Thanks for your advice!
Most of my experience is in a commercial setting, big buildings, but I am by no means a pro at pressure washing. I'm a pro at managing and maintaining big buildings and the associated systems and equipment. I rely on people that are specialists such as the people on this forum and highly respect the advice. I've been around a lot of people who think they are pros at lots of different things and the truth usually comes out when they can't walk the talk. In the Facilities world I have to know a lot about a lot of things, but don't have to be a specialist at any. Anyway, I'm going to try the mix Pat Norman suggested above and hopefully get all this stuff off my house. BTW, in 20+ years, very rarely have I had to use chemicals for washing, usually cold water pressure was enough. Only used chems on grease and oil.
