My guy I have been searching countless videos all day trying to understand what downstreaming and how this sh mixing works and this is the first time it’s clicked. THANK YOU
Excellent video, Joe. Its been fun watching you grow and learn, and then turn around and give it all back to us. I'd put you in the same class of people as Billy Davidson in Louisiana. He's also an awesome guy and great teacher as well. Keep up the great work!
finally someone explained this mixing process I am in NYC and I recently added power washing to the retail store front where I am doing floor maintenance, this was a great video and I am doing it tomorrow 😂
Hey, first video of yours I've seen. Starting a pressure washing business soon and this was extremely helpful. Thanks for the info! Liked and subbed, I'll stay tuned. Edit: Also have family from CT and you remind me of some of my folks!
Thanks for the numbers. I like it. Just a few things to consider (you May have mentioned it, and I missed it). 1. Running a 1.8 injector will cause you to draw more SH 2. The hose length will make a difference. 3. Your pressure at the pump will make a difference. Less pressure means more draw. Thanks again brother!
Mike Carmody Thanks Mike. Yes all of those things are absolutely factors. That’s why the first step of doing a draw test is key. As you know. I really appreciate your input.

Helpful, TY. Just a slight correction on your ratio, it’s actually 9:1 not 10:1... if you filled your graduated bucket with 1 gallon chemical and the result is 10 gallons total, then it’s 9:1 which would be slightly stronger shock to water ratio than your stated 10:1 ratio.
Hey Joe. Thx for the awesome video Ive been wondering if I can downstrean effectively with so many variables that impact draw rate and therefore no way to tell what I’m shooting. I’m going to do some draws tests now. If u ended up with 10 gallons, Wouldn’t u actually be a little hotter at 9:1 or 1.38? Also, I have to wonder if I throttle down will my SH ratios increase or do u think less gpm will pull less SH? Let me know what u think. Im gonna run several tests
The difference between 9.1 and 10.1 is negligible. 10.1 is just easier math. You really just looking for a range. You’re never going to get a shock that’s perfect anyway. You just need a rough idea.
Thanks for your vid. I’m getting the same 10 to 1 from mine and I was wondering what would be a safe mix so I wouldn’t burn plants or grass. (I know about pre soaking). Looks like 2 to 1 or even 3 to 1 SH to water I should be ok.
First and foremost, love your channel brother. Some things in the video are a bit confusing, and some have commented on it, and I agree. In the video, you say that your ratio is 10:1 (bleach to water). How is that possible when you start with 1 gallon of bleach, and then end up with 10 gallons of water? Should not your ratio read water to bleach? And should not the ratio be 9:1 (9 parts water to 1 part bleach.) If you end up with 10 gallons of water, and 1 gallon of it is bleach, 1 minus 10 is 9...1 part bleach, 9 parts water. You would then add the two numbers of the ratio together, in your case, 9 and the 1, which gives you 10. You would then divide 100 by 10, which is 10. When you subtract 10 from 100, you get 90. The "10" is your bleach, and the "90" left over will be your water ratio, giving you a 9:1, or 90% to 10% (water to bleach) mix. You would then take your bleach number, which would be 10%, and multiply by the percentage of SH that you would have. In your case, you're carrying 12.5% SH. 12.5 times 10 equals 125, which is 1.25% bleach at the tip of the gun if you're pulling straight bleach out of your chemical tank. If you're pulling a straight 10:1 (water to bleach), then in your case, you would add the two ratio numbers (10 and 1) which gives you 11. You would then divide 100 by 11, which gives you roughly 9.09. You then subtract 9.09 from 100, which gives you 90.91. So, 90.91 would be water, and 9.09 would be bleach, a 90.91:9.09. 9.09 times 12.5 equals 113.62, which comes to be 1.13625, basically 1.1% bleach at the tip. Not a big difference from the 9:1 ratio. The test works, just the ratio numbers are out of order. Water to Bleach, not Bleach to Water. Please check me to see if I'm right, hope this helps. You're doing an awesome job brother, keep it up!!!
You’re not wrong. Just over thinking it. Use the easy 10:1 math if you are in the 9-11 range. It truly doesn’t need to be that precise for what we do and just makes it more complicated. 10:1 = roughly 1.25%. Also if we are getting technical, how do you know what % your SH is to start? You can’t test it, might be older 🤷🏼♂️. Just keep it simple. You clearly are smarter than most. Again not wrong.
@@powerfulimprovements I tend to over think things a lot. Your videos inspire me brother, and I appreciate the feed back. I'm now 4 years into my business now, and still learning so much. Your channel is another tool in my tool box. Keep spit'n that wash knowledge, and thank you for what you do my friend, and keep spaying!!!
Hey how’s it going? I’m new to down streaming I have been soft washing for the last three years looking to get into downstream but my numbers are not coming out right I have 2-4 gallon a minute running siamese I’m getting 8.8 gallons a minute when I do my ratio test I’m getting about 17-18.1 on a 2.1 injector how do I do the math to get house wash mix at the tip.
Hello!! Little late to this party, but I do not currently have big tanks like you do. I have to start with 5 gallon buckets and a downstream injector. This is my first year power washing. My question is, just so I know I’m doing the math right, my chemical mix in my 5 gallon bucket would be 3 gallons of SH per 1 gallon of water? Then I also read 1/4 cup of surfactant for every gallon of bleach used.
Hey, would you be able to describe the parts of your pick up line? I am trying to find the right parts, but i am having a little trouble finding them. Thank you.
Hi Joe. I know you made this video a while ago so I’m hoping you still see this. In your draw test you said when you emptied the 1 gallon jug you had 10 gallons in the other jug. Wouldn’t that make your draw ratio 9 to 1 instead of 10 to 1? Thanks Joe. I love your videos 👍
I finally threw in the towel on xjetting residential houses. I just purchased my downstream injector and did my pull test. 1 gallon was emptied and I sprayed roughly 22 gallons into my tank. What would be my ratios? Or how do I calculate that? Running a 8gpm machine Awesome video.
10-1 is a great ratio for vinyl, but when you have a stucco home are you switching out your injector to something with a higher draw? if so which one??
Hey Joe! I just did a test on my 2.5gpm machine and I came out at 6:1. My question for you would be how is that possible? I got a 1.8 injector for the proper gpm but feel as it's drawing too fast. I'd rather not refill buckets all the time. Should I increase dsi size to pull less? Or just dilute my chemical 50-50 to get closer to 1% for housewashing. Thanks!
Thanks for the info Joe! So I have a 1.8 general pump injector, I did a draw test like you showed and I got a 20:1 ratio. So if I’m right, if I run a full strength 12.5 SH I’ll get .625 at the gun..right? If so, my next question is, is that strong enough for house washing??
@@powerfulimprovements I retested this morning and I was able to get 12:1 with my black tip. My JRod low pressure came out to 20:1, high pressure soap on my JRod came out to 13:1. I got a new siphon tube coming in tomorrow which I think will help since I’m using a cheesey little stock one for now. Think I’ll get me a new JRod and I should be on the right track. Appreciate a your help!
Great video!!! Quick question, if I'm running 12.5% straight through downstreamer, what is my dwell time on brick and or vinyl siding? Thanks in advance!
Depends on how dirty, how much organic growth there is, but downstreaming is only 1% at tip of gun, which is very weak, dwell time mostly 20-30 min but since it is such a weak mixture sometimes need to reapply
Hey Joe, for real bad gutters and such what ratio would you recommend? I deal with mostly people trying to flip houses so their usually in pretty rough shape and I can't seem to get them clean with just one or two passes. Should I increase dwell time? Roughly how long do you let the chemicals sit? Thanks!
@@powerfulimprovements thanks. Just starting and your videos have helped a lot. My four year old daughter asks if we can watch joe Darry with power improvements 😂
@@powerfulimprovements she's more excited about starting this up then me. Said as soon as she's big enough she's working for me. Hey one more question, how long do you typically let the mix dwell? Thanks again
I did a draw test and ended up at 5 gallons. So with a 5:1 ratio how would I mix up a batch? I have 12.5% SH. And also, what are you multiplying or dividing to get that middle number on your notes(9.375, 8.375, 6.25)? Thank you! Love the videos, learning a lot from you
3:1 = 3 parts SH, 1 part Water, meaning 4 parts total. 3 out of 4 parts is the same as saying 3/4, or 75% of the mixture being SH. 75% of 12.5% (base SH strength) = 9.375% effective SH in the batch. Then your 5:1 ratio means you divide 9.375% by 5, which gives you 1.875% effective SH at the wand.
Hey guys, finally gave in and got a downstream injector. I pulled test and pulled a little over 20gallons of water to 1 gallon of 12.5%sh. - using a 8gpm and jrod I am confused and new to downstreaming. I usually xjet but tired of lugging a bucket around.
Thx for the very informative video. I jist did a drop test. Can you please help me with some extra info? Ive putt a bottle of 1liter and filled 17 liters with it. ( black tip ) How can i make sure that i spray 3% sh (12.5) When i do it with a handpump i normaly putt 1liter sh (12.5) and 3 liters water. It takes a long time. That why i want to use the pressure washer for this. I really hope you have the time to reply. Thx again.
Plan on trying the draw test in the morning. Just wasn't sure because of my bleach is only 10.8% Truly appreciate the help and loving the videos. Will let you know how I make out in the morning. Thanks
Hi! I am from Slovakia EU and I started softwashing. My ds ratio is 10:1 and I have 10% sh. So my final percent will be 1%? This is not effective at roofwash or stucco wash
Hi .. ok i have a 4 gpm 4200psi.. its not a belt drive like yours.On my draw today... I got 24 gallons per 1gallon of soap ...So what does that mean..?? Is the injector clogged.? I know my down stream injector is built on there.. So i cant switch it.. feeling a little stuck... What do you say Joe.. Thanks in advance...
Yeah so roughly 20:1 has you putting out .50 at the tip. Won’t clean that great. I’ve heard of some guys plugging the injector. And adding a better one after it. However I don’t have any experience doing it
So i did my draw test. For 1 gallon of chem I am putting 12 gallons out of my wand. Woul it be safe to use straight 10.8 shock downstreaming and what would my on the wall % be? Thanks
I literally bought the same 15 gallon water jug after seeing this video, lol. I just did the draw test downstreaming a gallon of water and the jug filled up to 12 gallons. My math sucks. What would I be pulling with straight 12.5 SH? Thanks in advance.
The video clears a lot but ive got a few questions. Wouldnt your SH be 9 to 1 if you equall 10 gallons? And if you do your test run and it draws a 20 to 1 ratio how do you increase the draw rate of chemical to 10 to 1. to obtain a 1 percent solution
How do you come up with those numbers? Im trying to figure out what my percentage is at the end of my gun running 10%SH. And about 7ish to 1 on my bucket test
Im still having trouble finding an answer,,,, so if im using a 5 gallon bucket, how muh SH and how muh water to fill the bucket? Like half gallon sh and the rest water or,,, i dont understand all the 3 percent out of the gun etc stuff yet so im just teying to figure out a good safe mix thats hot enouh to do a vinyl siding with algae and a driveway,, whats a standard mix people use,, every video has giys woh huge 100 gallon tanks and i cant understand the ratios,, im just gonna use a 5 gal bucket and i dint how much sh to get and how much to put in the mix or do i run straight sh if my washer has a built in injector? Thanks in advance!
A draw test will determine what ratio your washer is pulling. If you have a smaller store bought washer with a built in Injector it is likely pulling 20:1. If you were to pull straight shock you’d be around .625 on the house. This will clean but may take more than 1 application
@@powerfulimprovements oh i forgot to ask! Also,,, im pretty sure my generac 2.8gpm has a 20:1 built on injector like you said, is that too diluted if im running straight sh? Would it be better to get an external 10:1 injector and attach it and run straight sh?
For roof washing if I need hotter like 3% what can I do? Is it just hit the area couple of time? As xjet bucket can’t get to roof is too risky carrying stuff while climbing the ladder.
can someone answer why can't you just downstream straight SH instead of mixing to get more than 1%, and also does that mean if 10:1 your highest you can pull from a powerwasher would be like 2%?
Well...if I squirt 10 gallons out of my wand while drawing 1 gallon from downstreamer my actual ratio would be 9 gallons water plus the gallon that came from soap jug. So I'd be working with a 9 to 1 ratio not 10 to 1. That would make all the rest of your figures change. You're running a little hotter than you thought. Nevertheless you found a mixture that's been working for you.
Hey bud, I probably be very dump to don’t understand very well.. I am doing it right now at home and I took a milk jar which is 3L and I got 36L out of my gun so my ratio will be 36L per 3 😑 can’t figure it out tho can you help me please?
@@powerfulimprovements just a couple questions I thought of, so is batch mixing just for soft washing? And if you’re using 10% bleach downstream if with a 1:10 pull ratio does that make what you’re spraying only a 1%?
Quick question.. say I pretreat a driveway with a DS injector do I just pull the siphon hose out of sh mix and start surface cleaning? Or will it suck to much air while cleaning and need to be in a fresh water bucket? I know I need to rinse it out with fresh h20 after im done but just wondering if the ds injector sucking air affects surface cleaner to bad
Josh Parks at minimum put the ds tube in water. You’ll get better flow to the surface cleaner if you remove the ds injector. Most of us put quick connects on ds so easy to remove
CC customs llc basically correct. Every once in a while I will make a 1% batch and soft wash siding but normally I Downstream lately and only use 12v for roofs
What is a good quality pump for soft washing you would recommend, I seen a diaphragm pump 5gpm 60psi for around 100 bucks or so. Think that'll be worth my time?
@@powerfulimprovements cool Thank you, do u know if sh is ok on painted aluminum railings on a porch, like gutters too. Is oxalic acid ok for those railings also and is it ok to mix those two sh first rinse then add oxalic acid to a deck or is that bad or piosonous

I added a downstream injector to the machine and I am pulling 5:1 with 10% SH. I figure that is 1.66%SH at the tip. Not really sure now how much to cut the SH with water to get it down below 1% for vinyl siding. Thanks for your help.
I believe, if I heard him correctly, his first number was SH and the second was water. So a 3gal bleach to 1 gal water would be stronger than a 1 gal bleach to 1 gal water
I thought the same but it’s correct. If his first number is his chem then of course the less chem in the mix, the less will be produced out the gun The only math error I’m seeing is writing the ratio as 10:1 to represent 10%, which would be incorrect. It would need to be written 9:1, 9 parts water to 1 part SH for a total of 10 parts. It’s written correctly in the list of mixes (3:1 = 75%, 2:1 = 67%, 1:1 = 50%) but not a huge difference so even if someone is misled I doubt they fry off someone’s siding or flower beds over it ya know
@@powerfulimprovements I really need to get a high draw 10:1 or something easier for Calculating ratios really thank you for the tip and your videos they have helped me a ton
So you’re never shooting more than .9% which seems really weak and he’s right! Not effective for roofs! That means. Downstreaming doesn’t work for roof cleaning! You would have to pump spray after wetting the roof prior. Maybe a little post wetting as well!
