So I finally did my first housewash that wasn’t for a friend or family member. It was for my parent’s neighbors. The siding was already very clean but the pretty high-up soffits were a mess, and I had just gotten my jrod so I knew I could reach. So I offered to do it for free.
It went fairly smoothly. I had posted the before picture on here a couple weeks ago and @Innocentbystander said to mist it with housewash mix and it would be gone in about a minute, so that gave me confidence that I’d be able to finish the job and not potentially be embarrassed if I couldn’t get the black stuff off. As usual, @Innocentbystander was exactly right. I sprayed it and about a minute later it was gone.
One hiccup I had was that I had come off the trigger for a little while in the backyard and had the gun pointed at the grass when I restarted and as you can imagine it blew up a streak of grass and shot dirt all over their vinyl fence. Easy to fix, but was a good reminder that I need to pay more attention.
I found in general that because the house had pretty tight quarters, I found myself unsure of where to point the gun when restarting. I didn’t want to hit the house with that start-up burst of pressure and I learned the hard way not to point it at the grass, and there wasn’t much cement around the house. So I ended up just pointing the gun straight up into the sky each time, to get that initial burst of pressure out of the gun. Is that what most of you do, or am I overthinking this aspect?
One last thing. As I mentioned, this house was pretty much clean except for the soffits so I was a little unsure of whether to wash the sides or just the soffits/fascia. On the first side of the house, I started by just shooting up high at the soffits, but as I did that I realized stuff is going to streak down the siding (or get wind blown into the siding) and could look bad, so I just decided to wash the sides too, even though they didn’t really need it. Maybe I used some SH unnecessarily, but I’m fine being a little wasteful on my first semi-real job. Is that the right choice to basically wash the siding, even if only the soffits needs it? Or maybe you professionals can be much more accurate and do only the soffits without affecting the siding at all?
Anyway, it took just under 2 hours from start to finish (including setup) and I probably used under $15 in materials (SH/elemonator/gas) so I certainly see how money can be made doing this work 
Please share any feedback/criticism if you have any. Otherwise, thanks for all the support on this forum, certainly feels good to get that first “real” one out of the way.
