First off, i have been reading a ton on here and learned so much so thank you all! I am up to page 66 in the residential section, and it has answered so many questions for me, but I have a few of my own.
For residential house washing - it seems like everyone has their own mix, but a very common one is something like (for a 5er): 2.5 gal 12%, 8-16oz simple cherry, squirts of dawn, and the rest H20.
I am wondering, is this for downstreaming, or X-jet (I will be starting off downstreaming)? I have seen some people say not to mix H20 in at all for downstreaming, and just run it straight, so that is where the confusion is for me. Also, how can I know or calc what final % I am laying on the house in terms of the 12%? I want to end up only laying like 1-2% right? Is there a straight formula for this so I can make sure I am not overly aggressing on someones house?
Next question - for roof washing, is the best way to apply your chems with a low PSI high gpm pump (shurflo), not your pw? Do these pumps just mount to their own lance, or is it basically through a garden hose and nozzle? then just use your pw only for the rinse? From my reading it seems like the roof chems need to be much stronger, like a 50/50 of the 12% and the h20. Is that sounding right?
I am honestly not trying to be lazy, and I do use the search button and have read tons, its just there are so many conflicting reports, so I would love to get some help from the pros (all of you). Thanks in advance all!
FYI, since I am in MN, I am planning on researching all winter then hitting it hard in the spring. Starting out very small with the machine I already have (3000, 2.5gpm), and then moving up after the first few jobs land me some $ hopefully :)
