I searched but can't find the answer, maybe because i'm not sure if im searching for the right thing so i'll just ask the question. This is a hypethetical question. If I have a 2.7-4.9 gpm injector and a 5 gallon tank, do i mix my chems per bottle instructions or stronger to account for the dilution rate of the injector? Not even sure I asked that right.

Bottle of what? Most of us use Bleach (SH), h20 and a surfactant mixed 2 gallons bleach 3 gallons water and surfactant. Or for a slightly stronger mix 3 gallons bleach 2 gallons water and a surfactant. Surfactant would be a soap additive. You can use gain dish soap, which is chlorine stable. Most pros use the vendors on these boards to buy contractor grade surfactants. If you are using a jug of concentrated pressure washing cleaner, just stick your hose in the jug and away you go.

OK that makes sense. Thanks

Most will give you a downstream mix ratio

Every job will be a different ratio, stronger = faster work but you'll have to make sure to take care of any plants.. weak solution is lots more work. Like I said though every job will need a different ratio.


Hey Kory did you get those roofs in arbor green awhile back? It was cool to finally meet you
