    Default downstreaming

    newbie question...
    my downstreamer dilutes at about 10:1.
    The SH i'm using is 10%.
    These past few houses I've done I've been pouring the sh into a bucket, mixing in the soap, and stirring it up... adding no water.
    I've been assuming this means roughly 1% is hitting the surface but I just ran across a post with some confusing math that has got me 2nd guessing now...
    What do you guys suggest?

    also, how much soap per gallon should I be using?
    I usually just put a few big squirts.

    deluxe dish detergent oxi, oxide cleaning power.
    Some stuff I got from the dollar store.
    Doesn't have any warnings on it about mixing with bleach.
    I can upload a pic if necessary.
    and on the downstream ratio, I filled up a bucket with 1 gallon of water and it took roughly 2.5 minutes for it to empty (my machine is 4gpm).

    my downstream injector is adjustable if the solution needs to be stronger.
    I'm looking into getting a small drum from univar within the next few weeks.

    Default downstreaming

    Knowing the ratio of your downstreamer is helpful, but other variables include: ambient temperature; the temperature of the water you're using; the % of sodium hypochlorite - which will change depending on age/exposure to sun/air. The performance of the downstreamer itself will degrade over time - especially if you don't use a ceramic ball. All of these variables will affect the ultimate % that actually is applied to the surface to be cleaned.

    should I continue to use it like I am or dilute it in the bucket then let the downstreamer dilute the rest?
    I've only used it on a few jobs and the houses weren't really moldy so I cant really tell how good its been working.

    Jeremy, you can get the Green Wash from Paul, Kassander, Russ Johnson, Pete Marantey, and JRacenstein. I do use it occasionally, but I mianly use Roof Snot from Russ Johnson for all my Roof Cleanings and House Washings.

    As for your Down streaming are you have any problems cleaning?? I see you said you ran across a post about the math, and seemed confusing to you, but I didn't see anything about whether or not your mix is cleaning or not. also what type surface are you cleaning, vinyl? brick? stucco????

    Your math is basically right, technically 10:1 has a total of 11 parts, one part being injected, so your a little under 1% hitting the house. A quick tip for down the road...a common problem with downstreaming I used to have (especially with hose reel, couple hundred feet of hose whip line etc) is that there is a bottle neck a the trigger that reduces the venturi effect. You want a gun rated for at least 12gpm, the best I've found is a blue one rated at 13.2 gpm, can't remember the name of it right now.
