Figuring Downstream Bleach Dilutions

Figuring Downstream Bleach Dilutions

I am often asked about figuring downstream bleach dilutions when pressure washing.  I have never really cared to know what the exact precise percentage of bleach to water is coming out of my gun.  What I am concerned with, is one important fact, is the bleach mix strong enough to change the color of the organic stains or not.   If it isn’t then I know I need to use my dedicated pump, like our Kingslinger Soft Wash System, or a pump up sprayer.  Always remember, that all a Soft Wash System is, is a pump up sprayer on steroids.  It allows you to get a stronger mix, like with a pump up sprayer, without having to re-fill the canister and continuously have to manually pump air into the sprayer.

The strongest bleach solution you can usually achieve using a General Pump Downstream Injector is around .8-10%.  If you have green algae which is easy to remove, then downstreaming will work for that. Once you get in to the darker and black mildew stains, then you need a stronger mix than downstreaming can deliver.  A pump up sprayer or soft wash system that can get you 20% or higher, is great for that.  For Roof Cleaning, you definitely need stronger mix ratios then what downstreaming can deliver.

If you are one that likes figuring downstream bleach dilutions, then here is a bucket method test you can perform. Also be sure to check out my Online Pressure Washing Video School if you are starting a pressure washing business.

How to manually figure out your dilution ratio on your pressure washer.

Step 1:

Check your flow rate on your pressure washer for 1 minute to see how many GPM your pressure washer is putting out. Use a container that measures gallons along the side of it and fill the container up for 1 minute and try to make sure to not allow any water to get out of the container as you are doing this test. (Ideally you will want to do this test with your rinse tip on the end of your wand)

If your container doesn’t have the markings, or a graduated scale, then you can manually mark them by using a measuring a cup to pour desired amounts into the container, and then mark them.

Step 2:

Test your upstream or downstream injector by getting a metering jug that measures ounces and fill it with water and put your soap line into the metering jug and draw the water for 1 minute. This will allow you to see how many ounces your soap injector is drawing in a minute.

Step 3: 

Doing a little math

For example:

If you have a 5 GPM pressure washer then you will do the following math to figure out your dilution ratio on your pressure washer.

5 X 128 (128 ounces in 1 gallon)=640 ounces

Draw rate in a minute: 40 ounces

640/40= 16 total parts, 15 parts water to 1 part chemical, so your dilution ratio would be 15:1 or some in the industry will say 1:15.

I am also including a link to a calculator that you can play around with, and may help you as well.

Five Roof Cleaning Tips

FIVE ROOF CLEANING TIPS

This FIVE ROOF CLEANING TIPS post is helpful for anyone providing professional roof cleaning service.  If you are new to the pressure washing industry, you may not be able to provide roof cleaning service at the start.  But as you grow your business, you can purchase equipment and expand the services you offer.  Roof cleaning is certainly a great service to add for any pressure washing business.  I hope these FIVE ROOF CLEANING TIPS help you decide if this service is right for your company.

MOSS AND LICHEN

Setting customer expectations is the first of my FIVE ROOF CLEANING TIPS when dealing with moss and lichen.  It’s important that the customer understands that moss and lichen will not be removed from the roof.  It will change color and usually turns white.  We explain that the mix we use will kill the moss and lichen, which is why it turns white.  With wind and rainfall over time, it will eventually loosen from the tiles but we never discuss a specific time frame.  We suggest explaining that it didn’t get there over night, so it won’t go away over night either.  Using pressure to attempt to remove moss and lichen from the roof will only do more damage to the integrity of the roof.

SPRAYING TECHNIQUE

The second of the FIVE ROOF CLEANING TIPS is DO NOT FLOOD THE ROOF!  The shingles just need to be wet but when water runs off, you’re simply wasting product and could possibly harm plant life below.  We use our 10 Gallon Per Minute Kingslinger soft wash system with a 2 Gallon Per Minute tip. This helps me control and preserve solution.

REMAINING TIPS

For the full details of the remaining FIVE ROOF CLEANING TIPS, be sure and watch the entire video.  We demonstrate use of Tyvek House Wrap from Lowe’s to assist with property protection.  Wetting plants before, during, and after the project is important to protecting the plant life from any degree of damage.  I also explain the use of guns versus using a ball valve.  If this post has been helpful, here is another one you might be interested in.

XJET MODIFIED FOR DOWNSTREAM

XJET MODIFIED FOR DOWNSTREAM

Have you ever wanted to use an XJET but without all the mist and pressure that the XJET puts out?  The good news is that you can do exactly that!  I’m going to walk you through an XJET modified for downstream.  Remember that as you are evaluating a job, you are evaluating three things.  You are looking at the surface type and stain presence, which then helps you determine which application method to use.  Application options include downstream injector, dedicated pump, XJET, or even a pump up sprayer.  The XJET is just one application for applying your bleach mix.

XJET SET UP

Here are a few preliminaries before the XJET MODIFIED FOR DOWNSTREAM is executed.  The XJET comes with hose, nozzle and proportion attachments that help meter the mix coming out of the XJET bucket.  Its very important when using the XJET bucket, which comes separately, to ensure the back valve is open.  This allows for ample ventilation.  Otherwise, the bucket will collapse as a result of vacuum suction upon draw.  One end of the hose will attach directly to top of the XJET bucket.

XJET MODIFICATION

The main step for an XJET MODIFIED FOR DOWNSTREAM is to install the main part of the XJET in between the gun and the lance of the pressure washing gun.  For more information concerning the BEST SOFT WASH GUN, click here.  Remove the quarter inch plug fitting from the XJET nozzle and the spring and orifice from inside.  Install a quarter inch threaded fitting directly into the gun.  We always recommend using teflon tape with lock seal to secure the fittings.  Next, screw the XJET fitting directly into the threaded fitting now attached to the gun.  Then there is another quarter inch  fitting with threading INSIDE which screws on to the XJET nozzle.  After you reinstall the wand, place the quarter inch coupler on the end of the wand.  Now, using the JROD for downstreaming along with the XJET modification, you have much lower pressure.  The same down streaming distance of 40 feet can be acheived with this XJET MODIFIED FOR DOWNSTREAM process.

X-Jet modified for downstreaming

EXTRA HOSE

The XJET arrives with an approximately 15 foot hose.  This will require needing to move the XJET bucket every 15 feet.  This will add needless time to every project that the XJET bucket is used.  We always recommend purchasing a 50 foot hose to use in place of the 15 foot hose it comes with.

XJET XTRAS

One of the great advantages of this XJET MODIFIED FOR DOWNSTREAM process is that your bleach mix is not running through more equipment, which means this equipment will last much longer.  In addition, this method means you will use more bleach.  This modification allows you to use your XJET as a downstream injector, which is great for post treating concrete surfaces with heavy landscape.  Mist and overspray is greatly reduced and much more controlled with an XJET MODIFIED FOR DOWNSTREAM.  I have provided a detailed video on my YOUTUBE channel link here which provides further insight and details for this.

Downstream Injector Check Valve

Downstream Injector Check Valve

For about the last eight months to a year I have been using a Downstream Injector Check Valve for Soft Washing. These not only help the injectors last longer, since we are removing the ball and spring, but they also actually make the mix a little stronger. We have been able to clean some porous surfaces that have the black algae stains on them, a little faster than using the injectors how they come. They are available on my store HERE .

Very easy to install, you simply remove the hose barb from the Downstream Injector.  Then you remove the ball and spring, which will pop out anyway. Attache the check valve where the hose barb was, and you are ready to attach your hose and start downstreaming.

Downstream-Injector-Check-valve

For the last few years there has has been a lot of mis-information about what soft washing is and isn’t.  As long as y9u are using low pressure to apply your chemical mix, and rinsing under low pressure, you are Soft Washing.  The use of a dedicated pump does not dictate that you are soft washing.   Downstreaming is the original soft wash method that I was taught to use way back in 1979.

While a dedicated pump will allow you to apply a stronger mix than downstreaming,  just like a pump up sprayer will.  In fact, thats all a dedicated pump is, a pump up sprayer on steroids.  If you want to clean buildings and houses faster, then using a downstream injector check valve is the way to go.  Your mix will be much stronger than a traditional injector.

I always encourage people starting a pressure washing business, to learn how to downstream first. This will help you learn to clean in a traditional way, and help prevent damage to landscape.

Pressure Washing Hose Care

Pressure Washing Hose Care

How you take care of your Pressure Washing Equipment plays a big factor in how long it will last.  One of the most often overlooked is Pressure Washing Hose Care.  We all try to prevent cars from running over them, dragging them through rough terrain, and other obstacles that our hoses face. One of the easiest ways to prevent damage is in the rolling up of your hoses onto hose reels.

In this video I show you a kink I found in one of our pressure washing hoses that was caused by the hose not being stretched out straight as it approached the hose reel. When at all possible always make sure the power washing hose isn’t twisted or kinked when rolling them up.

On our residential rig’s we install the hose reels on the passenger side of the trailer or truck.  This makes it easier to roll out and roll up because we position the reel to feed down the driveway.   When parking in front of a house, we always block the driveway with the trailer or truck.  The hose reel can then easily feed down the driveway.  Blocking the driveway also prevents cars or trucks from rolling over our hose.

Pressure Washing Hose Care

On our commercial rig, our hose reels feed off the back of the trailer.  With wide open parking lots, or areas to park, this makes it easier.  Especially if you are cleaning large concrete areas or need to move the truck and trailer while working.  Disconnects at the hose reel allows us to drop the hose from reel before moving.  Dragging a hose while moving the truck or trailer can cause damage to your hose.

Be sure to watch the Pressure Washing Hose Care video, and subscribe to our You Tube Channel  and hit the like button.  Leave a question or comment and I’ll be sure to respond as quickly as I can.

Starting a Pressure Washing Business?  I have a great online pressure washing school with over 215 videos.  I also have monthly Hands On Pressure Washing Training here in Houston that also covers Soft Washing and Roof Cleaning.  If you have any questions bout our training please contact me at pressurecleaningschool@gmail.com or HERE.

Pressure Washing Equipment Oil

Pressure Washing Equipment Oil

When owning pressure washing equipment it is very important to properly maintain your equipment.  Using the correct Pressure Washing Equipment Oil for your machines is very important.  I have switched all my equipment and trucks to the High Performance Lubricants brand of oils.  My equipment and trucks run much smoother and I also have more time between changes.  This saves me time and money.

There are many options out there to consider for Pressure Washing Equipment Oil, and most of us do like I have done.  Go to the auto parts store and get the oil that we feel is the best value.  That’s all well and good, but those oils are not really the best for the equipment we use, and how much and often we run them.

The High Performance Lubricant brand of oils do exactly as they say, give you High Performance.  I stock and sell them in our store, because I feel so strongly about them. You can find the ENGINE OIL HERE.

Also available on the store Site is Pressure Washing Pump Oil as well as Air Compressor Oil if you use an AODD pump for Soft Washing like I do.

These oils are competitively priced, only a little bit higher than the store bought brands.  The little extra you spend, you will make up on extended equipment life, less failures, and more time between oil maintenance changes.  Always remember to change your oil filter when changing engine oil.

If you have any questions feel free to email me or use the contact form on this site.  You can also text me at 281-883-3630.  Be sure to check out our online pressure washing school if you are starting a pressure washing business.  With over 200 training videos you will drastically cut your learning curve.
