Another Job we did this week in Kingwood Texas. I also put in a couple pic's showing how well the green wash sticks to the roof. A still picture I realize doesn't really do it justice, but the green wash really does stick better than anything I have used.
Here's a funny story. On a roof cleaning job last week I ran out of Green Wash when making another batch of mix. So I had to use Dawn, you should have seen my ground man running like a chicken w his head cut off trying to get at the run off. With the Green Wash he is used to very limited and SLOW runoff, this batch w Dawn was coming off the roof so fast he was having to run back and forth trying to keep up with it. It was hilarious. Felt like the old days and a trip down memory lane.
This roof was cleaned with 12 Gallons 10%SH, 53 gallons of water,a nd 48 ounces Green Wash. A roof I cleaned earlier this week I used 16 gallons of SH 10%. Going down 4 gallons did not seem to hurt the cleaning at all. I think I have honed in on my mix ratio. This roof was a lot dirtier than the one I used 16 gallons.
Now that is very impressive. One could achieve that ratio with a chemical injector on a 4gpm pressure washer with a 100 foot hose easily. Could def run it when you get a fresh batch after the supply truck leaves. They come at 7:30am m/w/f at my supplier so I could time it.
Nobody has ever been able to obtain roof cleaning power strength out of a chemical injector on a pw. But this math proves otherwise.
Doug can you test this out?

Seems to me I would have to mix it stronger if I am DS'in. to compensate for the water coming throught he machine. I would also think it would dilute the Green Wash even more. I personally dont thing it wold work nor do I think I would use that method to clean a roof. I can test it sometime at my own house when I slow down a bit. My wife keeps asking, "when are you gonna clean OUR roof?
I'm thinking that a 4gpm pressure washer with a hi draw injector will pull the same ratio that you achieved when mixing it all together. It should mathematicaly??? that's 22% you mixed up. Get some of the real fresh stuff and you could possible pull stronger with a pw'r.

We'll see. Downstreaming a roof, in my mind, would seem to be a pain in the neck though. Seems it would be a Lot more labor intesive than using my roof pump set up. Care to expand your thoughts on why you would want to DS a roof. Would be interested to hear thoughts.
I don't want to DS roofs, and my helper would cringe if I told him he would be pulling pressure hose up the ladder all day hehe!
I really like the flow and pressure of my 5.6 gallon and 4 gpm pressure washers with 0060's in them. A pool cage for instance would really benefit with the boosted cleaner, again using only one hose. This is with my application obviously... not sws stuff.

Ahhh....yes I could see where pool cages would be great DS'in. When I was in Florida (clearwater) I always used 6% Store Bought, mixed it 40% bleach 60% water, and DS. Worked great, Rarely would use a whole 5 gallon bucket on a pool cage.
Here is an email I just received from this customer.
"Doug, my wife and I are absolutely amazed at the difference in the appearance of our house since you completed the cleaning. I feel the money we paid you was some of the best home improvement money we have ever spent. Thank you for doing such a spectacular job!!!!!!!!!"
