This video details how to mix bleach properly when pressure washing or soft washing. If you have questions about how a chemical injector affects the mixture, this should help you in particular.
Unfortunately his math isn't accurate. An 80/20 mix is 20% not 2%..he says .2 is 2% but .2 is 20% he's not adding the extra 0 so he's saying 2% but his calculations are 20%
I came up with a simple equation to make mixing bleach easier when you know your target percentage of SH and your draw ratio: x = y*z x = SH % y = draw ratio (i.e. if your ratio is 5:1, then you'd do 5+1=6, so y=6. Or if its 10:1, 10+1=11 so y=11, etc) z = target percentage you want coming out of the gun This way, if you know your draw ratio and what percent SH you want, this equation will give you the correct percent of SH to be pulling from either a downstream injector or x-jet. And then from there you can use an online mix calculator, or the one in this video, to figure out a batch mix - how much water needed to dilute your bleach to get that percent SH drawn into the ds injector or x-jet. Great video!
Mixing ratios, have you ever asked the so called gurus and they always say join my monthly membership, I have and it sucks, especially starting out. A guy named Billy Davidson saved my ass, many times. No matter what job you pull up to, stucco, Btick, Vinyl, , whatever. The last thing you want to do is kill landscaping, grass, etch windows, etc. You will have to pay to fix it. Billy has put together a mixing ratio table that takes all the math and guesswork out of it for you, being xjet, jrod or whatever you use. This is in my truvk and I use it everyday, think smart guys. The price was 50 bucks, I got him down to 39 dollars, thats nothing in this bizz but it will save uour ass. aparker.kartra.com/page/hqI53
Great Video! I have been asking this question and watching hundreds of videos and no one has explained both dilutions the SH goes through to get the final product, thank you. It makes so much sense now!
This is the best video I have found about mixing and using a down stream injector. I'm trying to get down to 1.5% SH on certain jobs and I have a better understanding how to get there now. Thanks!
I have put together mixing ratios for 5 gallon mixes, weather your downstreaming or xjetting. so called gurus they want to charge you enormous amounts of money or buy into their program. I have cut that price over half. Please email for info. satmanjf@gmail.com. also includes roof mix and 1 gallon pump sprayer. All you will ever need
Absolutely Best Video out there to help understand both down streaming and Soft Wash. I looked everywhere to try and figure out what the percentage of water to bleach was coming out of my pressure washer. Thanks
Excellent job. You think the people that sell the pressure washers would tell you this but they don’t leave it up to you to figure it out. Which I did 25 years ago. Great job
Thank you, thank you, thank you. I've been asking for months and just getting roundabout replies. This made it so simple and easy to understand. Thank you again.
I want to take this opportunity and say thank you. In the world 🌎 we live in, so many people would not share this information. You took the time to help and I really appreciate that. I not only subscribed to your channel, but I gave you a thumbs up. Once again thank you and God Bless.
Man I’m a 21 year old young man yano starting a pressure washing business and I felt like I had everything down and you just helped my biggest struggle I appreciate the hands on learning for people like me 🤟🏼❤️
Yo.. yooooo, was I the only one that noticed This guy is using both he’s hands to write on the board! Haha very nice. This helps your brain to think with both parts of the brain that is used for either the right or the left hand. Very smart. Also great video! You knew how to explain in detail, thank you. This will help a ton
I loved the vid and the math is flawless. The nerd way or if this is not the first time you had to watch the video ;) desired concentration = how strong you want your mix to be concentration of your chemical = how strong your bleach indicated on the label bleach content = gal of bleach in each gal of water. 0.1 bleach content means 1 gal of solution is made out of 0.1 gal of bleach + 0.9 gal water. Replace gal with liter if metric ^.^ Soft wash: [desired concentration] / [concentration of your chemical] = bleach content 2 / 10 = 0.5 5 / 15 = 0.33 Downstream: ([desired concentration] / [concentration of your chemical])*5 = bleach content, if bleach content is larger than 1, then to desired concentration cannot be reached with a venturi/down stream application. (2 / 10) * 5 = (0.2) * 5 = 1 (5 / 10) * 5 = (0.5) * 5 = 2.5 ==> impossible to mix with DS (2 / 15) * 5 = (0.133) * 5 = 0.665 ==> have to dilute the chemical before down stream application. ***image of a potato***
i use a small barrel like 30g. i set my mixer to pull from it thru my ef7000 pump and softwash spray the mix i did in the barrel. I always rinse then rinse the shrubs that were pre soaked again. i really like the video you did
Thank you! There is so much to know about pressure washing, roof washing, etc. That is why David is a big proponent of power washing journals. It’s a great tool to be able to look back on knowledge you had once attained but have since forgotten.

I skipped over the video at first because I thought he was going to talk out of his ass but then decided to give it a chance. This is by far the best video I have found where they explain in detail everything you need to know.
I watched this video a couple of months ago when I was first was looking to do this and I was like WTF??? Now I knew what he was gonna say before he said it! Lol thank you bro for the video!
