I know it depends on what the surface looks like (what type of prep needs to be done) but what is your go to solution that helps you power wash your exteriors?

Right now Krud Kutter and bleach. If the white gutters are real dirty I make add a little borax and about a pound of arm and hammer to make a paste and coat the end of my scrub brush and scrub like carzy.

Recently we have been using Jomax and its working really well. Bleach is obviously one of the strongest products but it is so strong it can ruin wood(dry it out) and kill plants. Jomax kills mold and mildew instantly while removing tough dirt and stains and no worries of plants around.

Jomax + Bleach + Water. Diluted Spray 9 for gutters, but I may move away from that and try something that will not affect the factory finish. I may actually move away from exteriors all together

Are you talking about a housewash for cleaning or a housewash for prepping for a repaint??

Good question. There is a difference.

For paint prep I use TSP and bleach.

For House Washing I use Pressure Tek's Simple Cherry, 1.5% bleach, Potasium Hydroxide (Bob's F-13), Dawn, and a dose of Consan Triple Action 20 mildewcide/fungicide. Then a wax.

For an exterior with vinyl or windows and such I will just use my normal house wash.

I think the Simple Cherry is Tripolyphosphate (TSP substitute) along with some surfactants and a rinse aid. The rinse aid is most importantly to me becuase you avoid spotting windows. Stuff like Borax and other detergents will clean but may not leave the best results - spotting.

Ya got to where unless I was personally there I don't add any F-13 to the regular mix. Had a deal last summer where some windows got a bit etched.....(rinse rinse rinse). I can honestly say I'm not sure how much TSP if any is in simple cherry. I know TSP has more of an "etching" quality (seems to me anyway).

Simple Cherry does not have any TSP. It is the TSP Substitute (TPP) and it is not as harsh if at all. It also has enough buffers where TSP is straight juice.

The F-13 with the Dawn and SC definitely makes more rinsing time but the mix works well on bad areas and, oxidation, and gutters.

Ya I'll add F-13 if I'm on the job but if I'm not then I don't have them add any. I use F-13 exclusively on guttering and some other areas. I love the new formulation of S/C . Generally I hand brush gutters. We do a lot of gutters on Brick homes and they're loving it.

Used S/C for well over two years now Love it...
