I guess I am just stubborn. Been reading posts about downstreaming for two years but never tried it on a house or building. I had some time today so I did a test on a nasty tree house. Pictures one and two starting on the left are before and afters downstreaming on a 50/50 mix of 12% SH and water along with some Dawn. Had 150' of hose on and used about 1/2 gallon of chem.
The other two pictures are a different side before and after with an x-jet. Used a 50/50 mix of 12% SH and water with some Power House in there too. Used about the same amount of chemical.
I would never have thought downstreaming would put enough chemical on there to clean something that bad. I will definitely need to try this out on some houses.

The siding on there is vinyl.
