I typically put on about 0.6% and that will clean 95% of the siding I do. Even if it’s nasty, I don’t go more than 1%. You will be fine at that percentage.
I dilute 12.5% normally 3g SH 2g water downstream and i find it works fine normally
That’s right.

Look out world. I can calculate SH% and use that psi/gpm nozzle chart. That puts me right into the upper echelon of the forum I think. 
I kid I kid. I AM learning a lot here. Problem is I learn more, and then have even more questions.

You’re better than me. I’ve never figured out the nozzle chart or cared what my ratio is. I’ve used the same type of equipment for a couple of decades and just know what I need for them
