PRESSURE WASHING CHEMICAL MIX

PRESSURE WASHING CHEMICAL MIX

One of the questions I often receive relates to PRESSURE WASHING CHEMICAL MIX ratios from a downstream injector.  To be straight and honest with you right up front, I have never really measured the final ratio using a downstream injector.  We use 5 and 8 gallon per minute machines, but mostly 8 gallon per minute machines.  We use a 3-5 gallon per minute injector with a check valve. This PRESSURE WASHING CHEMICAL MIX video will delve into many of the details around this important question.  Pressure washing business startups might want to watch and listen carefully to increase efficiency, preserve solutions, and maximize profits.

COLOR CHANGE

I am not too concerned with the precise pressure washing chemical mix ratio.  What I do look for is color change.  The main thing I look for when down streaming is will the mix change the color of organic stains.  If I do not see a change in color, this means my mix is not strong enough.  At this point, I will need to use a dedicated pump such as my KINGSLINGER soft wash system.  This will certainly provide a higher, stronger mix than a downstream injector.  This is a 27:00 video so make sure you view the entire video to absorb all the details.  I also provide job site before and after pictures for demonstration purposes.  Always prewet the surfaces and saturate the grass or landscaping in the area with water.  This is fairly quick and easy to do with an open ball valve.

MUSTARD MOLD

This pressure washing chemical mix video includes a brick cleaning project with gold mold or “mustard” mold.  This particular organic stain will not undergo much of a color change.  This mustard mold stain is very popular in California, especially on various roofing materials.  It is extremely difficult to remove.  It’s very important to set customers expectations when you see this particular organic stain.  You might also be interested in checking out my full line of pressure wash cleaning solutions.  I hope this information helps!  My passion is training pressure washing startups to succeed, improve their skills, and expand their pressure washing business services.

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.

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.
