Here is something that I use and have had great results with downstreaming.
5 gallons of the 10% or 12.5% then add 1.5 cups (scoops) of PressureTek's Simple Cherry and mix then drop the downstream injector hose into bucket and start downstreaming.
This soap has a lot of stuff in it so on the Hot Texas Days, the stuff will dry on the windows, even very expensive windows and I just rinse off. I had 2 instances where it dried real good so I just sprayed it with more housewash mix and then rinsed the windows and they are sparkling clean!
This is the only soap that I can let dry on the windows and had good results with just rinsing with low pressure, I would not try this with other brands of soaps because I learned about this the hard way. Nothing against other brands of soaps, I just know this works great for me.
For housewashing, this is the only thing I will use because down here, everything dries very fast so you need something that will come off easily if it dries and this product is great for that.
Only mix what you need for the job as this will not be strong for house washing a week later, just the climate here.
If you X-jet then you could dilute the bleach a little bit so it will go further, I am not sure about how much soap to use as I downstream like 99% of the time but on some occasions, I will dust off the X-Jet and use it so you will have to experiment with the amounts of soap.
You will probably be ok with 1.5 scoops into a 5 gallon bucket, might just have a little more soap on the surface but it rinses off nicely.
Hope this helps.
