Welcome to the channel, where we provide the best tips and tutorials for all your pressure washing needs! In today's video, we're diving deep into a crucial topic: *"How to Mix Bleach for Pressure Washing."* Whether you're a seasoned pro or just starting your pressure washing business, understanding how to mix chemicals correctly is essential for achieving optimal results and maintaining safety.
*Why Mixing Chemicals Properly is Important*
When it comes to pressure washing, the right chemical mix can make all the difference. Using the wrong proportions or types of chemicals can damage surfaces, reduce the effectiveness of your cleaning, and even pose health risks. This video will guide you through the process of mixing bleach, specifically sodium hypochlorite, for various pressure washing applications.
*Understanding the Basics: Sodium Hypochlorite*
Sodium hypochlorite (SH) is a common bleaching agent used in pressure washing. It's effective for removing mold, mildew, and stains from surfaces like house exteriors, driveways, and roofs. Knowing the correct sodium hypochlorite mixing ratio is vital for ensuring effective and safe cleaning.
*Step-by-Step Guide to Mixing Bleach for Pressure Washing*
1. *Gather Your Equipment:*
- Pressure washer
- Downstream injector or x jet pressure washer
- Measuring containers
- Personal protective equipment (PPE) such as gloves and goggles
2. *Determine the Right Mix Ratio:*
The mix ratio depends on the surface you're cleaning. For general house washing, a typical mix might be 1 part sodium hypochlorite to 10 parts water. For tougher stains, and, or roof washing, a stronger solution will be needed. Always refer to specific guidelines or manufacturer recommendations for your pressure washing chemicals.
3. *Batch Mixing Soft Wash:*
If you're not using a soft wash system, you'll likely be batch mixing your chemicals. This involves preparing a large batch of your chemical mix and drawing from it as needed. Ensure your batch mix is consistent.
4. *Using a Downstream Injector:*
For downstreaming pressure washing, you'll use a downstream injector to mix the chemicals automatically with water from your pressure washer. This method is convenient for continuous cleaning without manual mixing. Learn how to set up and adjust your downstream injector pressure washer for optimal chemical delivery.
5. *Safety First:*
Always wear appropriate PPE and work in well-ventilated areas. Bleach can be harmful if inhaled or if it comes into contact with skin or eyes. Ensure you have a neutralizing agent like vinegar on hand to counteract accidental spills.
*Special Tips for Different Surfaces*
- *House Washing:* Use a softer mix to avoid damaging siding or paint. A typical house wash mix involves a lower concentration of sodium hypochlorite.
- *Driveways and Concrete:* Pretreat concrete before pressure washing to loosen dirt and stains. A stronger bleach mix can be used here.
- *Roof Washing:* Roof washing requires careful handling of chemicals to prevent damage to shingles and surrounding vegetation. A roof washing mix often includes additional surfactants to help the bleach adhere to the surface longer.
*Maintaining Your Equipment*
Properly mixing and using chemicals not only ensures a great clean but also helps maintain your pressure washing equipment. Regularly clean your downstream injector and other components to prevent buildup and extend their lifespan.
*Pressure Washing Business Tips*
For those running a pressure washing business, efficiency and safety are paramount. We'll share insights on streamlining your mixing process, managing chemical supplies, and ensuring consistent results for your clients.

Finally a video where the instructor is spot on and explained it so a child could understand it. Thank you
That's right!!
Amen!
I need that lol
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%
It’s me I’m the child

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.

50% chlorax 50% water in a bucket. I barely had tolerance for the math.
He keeps saying it's a 4:1 ratio which is a 20% chemical draw rate with 80% being water, but that would be a 5:1 ratio wouldn't it? 4:1 would be 25% draw with 75% water.
Thank you man, that is the first video that explains it so well. I really appreciate your knowledge. Keep up the great work.

Whats the ratio of Solvents to Surfactant. i.e. how much soap per 1 gallon of SH ... Thanks
So if Im using a Downstream injector and I want a 1% mix, opposed to a 2% mix, all I'd have to do is mix my 5 gallon bucket halfway with SH(10%) and the other half with water. Correct??
I almost never mix because down streaming dilutes it plenty
This actually explained how to mix unlike other videos that just say "Mix this with that and you're done." Thank You
How exactly is 80% water and 20% bleach a 2% mix? Correct me of I'm wrong but last time I checked 20% of 100 is 1/5 or...20%..just to be clear 2% isn't .2 it's .02
Adding the 0 makes a big difference
Excellent video. I finally know the mix percentage AFTER going through the downstream injector! Thank you. You earned my subscription.
🙏🙏🙏
Very informative.im planning to do soap washing.
Thanks so much man this video was super helpful and made things much easier to understand. Although 4:1 is a 25% mixture not a 20% mixture so the SH would he 2.5% not 2%
No, a 3:1 would be 25%. If you have 4:1, you have 5 parts. 4 of water 1 of bleach = 5 parts. In 10 gallons 8 would be water, 2 would be bleach this 20%
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!
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 🤟🏼❤️
Hey in 21 starting up my business aswell hows it going for you?
@@phntmkthis is his father . Cub killed himself last week. Business did not pan out
@@thomasburr9244I’m sorry for your lost, your family will be in my prayers. My deepest condolences
Thanks Dave. You cleared up a major question I had. Subbed.
Great video, though im a little confused... I did a draw test with my 2.5gpm simpson, running a GP 2-3gpm 1.8 DI, at the end a jrod 1/4 MEG 2540 tip. Filled a 5g bucket w/ water for the draw test and stuck the spray tip into an empty 5g bucket. I ended up pulling 2 gallons from my "chem" bucket by the time i filled the empty 5g. That tells me im pulling almost a 2.5% mix or 40% injection ratio. So how is that possible if what you're saying, that a DI will only pull 2% max?
Thanks again for the very informational vid. Ckean and concise!
The app for batch mix I have on my phone (BATCHMix) says 2 gal bleach + 3 gal water (assuming you're using 12.5% bleach) = a 5% cleaning solution. (4% if you have 10% bleach)
FINALLY!!! Thank you for your help. Everything finally clicked in my head.
what do i with 12.5 %? that’s what i have
Multiply your final number by 1.25 - 12.5% is 25% more than 10%.

Total rookie, here. Thank you for breaking this down. My take is that if I buy 30 Second Outdoor Cleaner and use the siphon tube connected to my machine, I should NOT dilute the cleaning solution. Did I get it right?
I wouldn't dilute but go to the pool supply store and buy liquid pool shock. Cheaper and will clean 5 times more than the gallon of 30 Second Outdoor Cleaner.

What are your thoughts on chem percentage at the tip for Xjetting?
Going to have my employee watch this. Thank you, good knowledge to refresh my memory also.
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 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
Watering is definitely key to landscaping. Look at using post bleach wash to reverse the effects of the sodium.

How much surfactant do you add to the 5 gallon example
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!
How do you find the draw ratio of your down streamer?

Sorry if this is a dumb question... So using 12.5% and aiming for 3% the equation would look like:
3 / 12.5 = .24
.24 x 5 = 1.2
Add 1.2 gal of SH and 3.8 gal H20 to get 3%... Is this correct? Thank you!
I liked the question but all I wanted to know after that was how to squeeze the surfactant into the equation without disturbing the maximum amount of gallons that could be used and if I used a bigger bucket and then added surfactant how would that work😢
Can we use chemical injector and foam cannon at the same time?????? Please help
You can probably but I wouldn't recommend it. However, if it works, go for it.

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!
Good explanation, thanks.
Thank you. You have made me a one happy guy. I’d give you hug if I could. Nice explanation.
Thanks for the instruction.
I’d love to know where you are finding a 4 to 1 downstreamer. I’ve experienced more like 10 to 1 or higher. Pretty much have to downstream straight 12.5 with surfactant
20 years in the pressure washer supply and service industry would also like to know who makes his 4 to 1 injector??? think it would be a top seller
@@EluderRacing they're literally the first things that come up on google when I google 'downstream injector"
4-1 is 8-2 and he said around that, 10-1 is relatively close.
Mine is 12:1...
Glad I found this video. Very much appreciated man
So I have a M-5 Xjet and I want to use as OPEN sucking up form a 5gallon of 10% SH.
What would the SH% actually coming from the Xjet ?
Wait a minute. So when downstreaming in a 5 gal bucket I should have nothing but bleach? I thought I was supposed to mix my batch in the 5 gal bucket?! I'm new to this! Lol
If you want a 2% mix then down streaming with a 4 to 1 high draw injector will put you at 2% with 10% sh...
We give you the equation though. Plug your numbers in and see what you need to mix.
And what do you mean batch? That’s sh, water, and some surfactant if you deem it necessary
@@TradeSchoolConsulting im confused... isn't 4:1 a 25% and 1:5 a 20%?
Josh parks, 4-1 means 4 gal of water coming out per 1 of bleach... 4+1 = 5 gal total
This definitely made more sense than other videos that assume. So, if I am downstreaming, would I just fill my 5 gallon chem tank up with 100% bleach every time and never mix it with water of any percentage? Let's say if I was cleaning concrete with a application of 3-4% and am using a 12.5% SH, just fill the 5 gallon up with bleach, put the chem hose in the 5 gallon, and what comes would be the 3% mix no matter what? Someone help lol
Awesome teacher .thanks
How much surfactant do I use for downstreaming out of 2.5 gallon of bleach?
if you run dual downstream injectors inline do you get a 4% mix? 3 would make 6% plenty hot enough for roof washing and stone work
I’m a first timer.. I want to clean my driveway at home, can I just use my solo sprayer that I use for my lawn care to pre treat the driveway? If so which nozzle should I use?
It doesn’t produce pressure though..
Some sprayer internal seals and O rings are not rated for bleach, and to do so will destroy the seals eventually.
Absolutely correct!

What about using a dual-port chemical injector? Does that change the ratio? Does it double it to as much as a 4% (bleach) rate for cleaning?
Dual barbs are relatively new. You would need to verify that the dual barb injector is a high draw with 4:1 ratio. A dual barb will allow you to double your draw rate. If using 10% sh, you could get as high as 40% mix ratio. 40% sh and 60% water
(Adjust if using 12.5% sh)
@@TradeSchoolConsulting Awesome! Yes, it is a high draw dual barb injector. But its s 4 GPM pw. Thanks for the answer!
It's a very informative video. The end of the downstream part is very unclear though. It's easy using a 4:1 ratio. My pw is 12:1. If i had a 5 gallon bucket of straight 10%, I'm doing your math and get lost at the end. It's not clear. Trying to get 1% or less.
12:1 injector with 5 gallons of straight 10% would give me .8333? Just under 1?
Lol my pw is 15:1 a 12.5% bleach can only give me like half a percent if i did my math right. Time to get a 12v pump
how much solution per square foot?
That will depend on how dirty, how much growth etc. I've cleaned 3k sq ft houses before with less than 1/10th of a gallon. I've also cleaned 1500 sq ft houses with 5 gallons of SH. You'll become skilled at determining the amount necessary as you proceed.

Thank you so much. Great explanation for entry level washers like myself!
I got some crystal 12.5% SH and I have a 15 gallon container I want to mix it in. How much SH should I put into 15 gallons. I'll be applying with a garden sprayer directly to the surface.
Projects we do are lots of decks that are black with algae and growth. And washing sides of vinyl buildings. And I use a garden hose to get it off.
So how much 12.5% SH should I use? Should I add any soap to clean or is the SH also cleaning?
Holy shit finally someone with good explanation 😭😭
I did a downstream test. I emptied 1 gallon of 12.5% bleach with 11 gallons of water, then how much % is the bleach now?
TYIA
I have a 5 gallon jug of sodium hypochlorite in my garage I’ve had for 3 months. How long does it takes for Sodium hypochlorite to degrade?
I appreciate you
Literally the best video that tells the difference with a great breakdown . Love the math as well . Definitely got a subscriber in me
If I have SH 12.5% and I'm going to just put it into a regular garden sprayer to spray on our deck for the bad algae that has made the wood even turn bark. What is the ratio of water to SH 12.5%
Awesome teacher.
So you are saying you can never get 5% from down streaming???
That is correct - most downstream nozzles are 1-2% pull. So even if your soap is at 100% - the injector will pull 98% water and 2% detergent. If you're doing roof cleaning, get a dedicated pump. That's your best bet.

@@TradeSchoolConsulting thanks
the best educational video on mixing chemicals. Thankyou for awesome content.
Beginners Question -------Is 2% the best ratio in cleaning a concrete driveway ? Can I apply that ratio in a 5 gallon bucket and then pour it on my driveway in sections using a broom to evenly spread it then finishing off with my electric pressure washer with a surface cleaner ?????.
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***
For down streaming using a 2.5 gpm do I still use only bleach in the bucket? Or does gpm not matter?
Doesn't matter, just the ratio the downstream uses
If you are at fault in an accident and have insufficient insurance to cover medical bills you will LOSE YOUR LICENSE. Don't trust cheap insurance.
Thank you so much for breaking it down so well
Is there a difference in injectors. I’ve read 20/1,,,,10/1. What does this mean?. I have a 4.2 gpm pump with an adjustable injector that reads. 2.0. What does that mean. I would be pulling straight bleach from a bucket, but still don’t know what my % is at the surface. Totally confused
4 to 1 downstream.. is with any gpm washer?
Great question. Gpm doesn’t effect the draw to a degree. It’s the chem injector . Make sure you have a chem injector meant for your gpm at a 4 to 1 ratio.
You certainly wouldn’t want a 4gpm chem injector on an 8 gpm machine because you wouldn’t be able to determine what the draw would be due to the fact that the ratio provided is based on the flow rate it was designed for.

I’m about to ask the stupidest question ever if you mix 2 gallons of SH both of them are 10% would you have 20%? Lol
So just to be clear right guys...so can i still use surfactant using downstream or not....thanks...dont get angry ok...😁😁😁
How many sq ft does that 5 gallon bucket at 2% down streaming cover ? I need to cover 24,000 sq ft
What am I missing here? Why do people in the softwash business say that a 5% mixture is 50% bleach + 50% water = 0.5? Where I come from 0.5 is 50% and 0.05 is 5%?
*watches 8 videos trying to piece all this shit together

Hello, my English is not very good so I haven't been able to understand everything. If I use DS and need a 5% bleach mix how many gallons would I need? my tank is 30 gallons.
Only one problem... Almost all power wash Mfg. Say do not run bleach through the pump, it will eventually ruin the seals in the pump.
What if I am using the x jet and filling 5 gallon tank. How much SH and water am I adding to the tank? Is using the x jet considered Soft washing or Down streaming? Thanks in advance

So if I'm dowstreaming and I have 12.5 SH I can use 4gallons and it would be around 3% more or less
i under stand the equation to an extend when coming to down streaming so i need a bit of help. if i want a 1% mix and i have 10% bleach its 1% / 10% which is .83333 so per 8.333 of bleach i need 4.16666 water with down streaming its already 4 to 1 for ratio how do i get the correct ratio? do i do .83333 water and ad the .16666 water to the down stream mixture? per gallon?
Good info, but on the math side of things 1/4 does equal 25% and not 20% , so you should have 25% bleach and 75% water. ( not that it matters)
THANK YOU. i needed this. i Wouldn't have realized durp the machine mixes with the mix to spray. Mmmm Math :)
Great video , I pump from 5 gallon buckets clean mostly concrete or pavers I use 12.5 bleach. Pump with a a 12 volt pump. You were saying to get to 2% was1 gallon of 12.5 sf to 4 gallons of water and I use a surfactant @ 1 oz per gallon . Is that a good starting point for driveways. And will that harm grass and plants ? I always rinse with a bleach neutralizer. Not sure how strong 2% is. Thanks any advice would be great.
I don't have a soft wash unit yet ( when I can spare the $ I'll be getting one ) ...so this is gonna be an odd comment I know lol
But since My down stream injector is only going to give me a 2% mix ..can I go ahead and spray the roof 3 times to get at the 5% required ?
The one that customer wants done is nasty ..
( if so then my reasoning is I don't wanna take my hand pump sprayer 3 gallon and try it as it'll take me forever and a day doing this 850 sq ft roof
maths isnt my strong suit but i gather its the same in metric? if I have a 5 liter bucket . so if i want a 3 % mix from 10% bleach, i go 3 divided by 10 = 0.3 then 0.3 x 5 = 1.5 litres of bleach into a five liter bucket . so 1.5 liter bleach and 3. 5 liter water gives me a three % mix and 5 liters total ? ( i am not down streaming )
Couldn’t you make your bleach 2/3 water and 1/3 chemicals? Then you’d have a higher percentage mix right?
Het mate. I use a 6liter hand pump to apply the mix. Quick question if i want a 3% mix how many hypo should i apply to the 6 liter hand pump. Thx in advance
Great video just what I’ve been looking for. Thank you. Can you create a video of what % to use for roof? Siding? Concrete? Etc.
Email info@tradeschoolconsulting.com
and ask for a ratio chart. We will email a chart to you that you can use as a guide and understand that stains or growths vary in each circumstance. This chart is a suggestion for the different surfaces you may encounter. Thanks
@@TradeSchoolConsulting is this still a thing? I could really use that chart
Thank you for your help, i needed this. Have a great evening😊
So basically in order to have to full control of your target percentage, meaning going from let’s say concrete to vinyl siding, you’d have to use a soft wash system so that you can achieve more or less than 2%, am I right?
If I downstream on a 3 gpm pressure washer and I fill my 5 gallon bucket with 10% sh what is my percent
2%, GPM doesn't matter in this case, it only determines how fast it's pushed.
Damn good informative video brother

What’s the difference between downstreamong and upstreaming?
Wouldn’t all this math for the down streaming depend on the GPM??
Had to watch it 3 times to truly get it...but that's because I was drinking... think I got it
I've never tested this but have always wondered what would happen if you added another down stream injector? I mean why wouldn't it work? For example we know our x-jet puts out 2% SH when the mix tank is 100%. That's the max percentage we can get out of any downstream injector (to be honest it's more like 1.5%). So in theory if we added another downstream injector you would think our percentage should go up another 2% but that's not the case or is it?
They have dual barbed chemical injectors.
@@TradeSchoolConsulting Just when I thought I was a genius you had to pull me back in! I've never ran across the dual barb but sounds interesting. My math tells me if you where running two down stream injectors the first one would be normal at around say 2-3% and the second injector would pick up the same plus 1- 1.5 % additional equaling 5-5.5%. Of course this depends on several Variables like do we have any suspected added and how much what type. Then you have the main variables like orifice size creates how much psi and machine gpm rating. I believe all of us have had our machines run a little wacky and have that happen when using an x-jet draining that 5 gallon jug pretty Damm fast for some reason. I also believe that most of us know that everyone soap nozzle is the same size. Any how's it would be a fun test to run. I know I'm a huge believer in running pumps parallel and will never give up my 42" and 48" surface washers.
When down streaming, how do I know how much water will automatically mix with the bleach?
I wish you went deeper in depth on surfactants. If I want to use surfactants how much should I use? Is there not a clear ratio like with bleach? Can i just eyeball it?
question please David, if I use your ds mix example and have a 2:1 injector would that give me a 4% mix ?
So I have my 2.5gpm machine which has a siphon that does a 7:1 ratio so if I use 10% SH and I want to get a 1.5% for vinyl wash I can just fill a bucket with just sh and soap, correct?
The equation is in the video. Use it. I said 4:1 just drop it in. Not 7:1
1.5 is pretty hot for house wash be careful
