Preparing to pressure wash / soft wash

Josh Wagner - Power Wash Trainer (00:00):

All right. So the first thing that we're gonna be doing is just watering all the vegetation down on the front of the house. As you can see, I basically just hooked up a garden hose and I'm going around basically getting everything wet, making sure that the first thing that touches these plants for today is just water. I'm literally just doing the oldest trick ever. And just putting my thumb over top of it. You don't need anything fancy. You're just getting them wet. So that the first thing that they get is not some sort of detergent. The other thing that this does is it allows my garden hose to get completely flushed out. Let's make up something and say that the homeowner hasn't used this garden hose in six months, maybe even a year or so, there could be all kinds of bugs debris, all kinds of crap has just built up in it. By flushing it out like this. You basically just increase the filtration capacity of your machines. You're flushing out that hose before anything actually touches it and basically getting it ready for a day's worth of use. So that is step one, go ahead and shut it down.

Caller hose, rinse. We'll pull over our machine and fire up.

Chemical Mixing and washing brick façade

Josh Wagner - Power Wash Trainer (01:20):

All right. So like I said before, our primary ingredients are going to be Big Green Bruce and sodium hypochlorite. On the front of this house we need a little bit stronger remix for the brick. That's not that dirty. There are some inconsistencies with it. So what we're going to do,

Josh Wagner - Power Wash Trainer (01:37):

Throw a couple of splashes of that in there. And then for the back of the house, apparently I needed about half as much. That was not an exact measurement, but if I had to guess, I would say I'm somewhere in the 8 to 10 ounces for this. And on this side, I'm closer to the four to six ounces. It's a good mix. So it'll give me a decent amount of sud. It'll also serve its purpose as we're working around the building. So back of the house, front of the house, we're just gonna shake up the buckets and go ahead and plug everything in.

Downstream injections vs upstream injection with a pressure washer

Josh Wagner - Power Wash Trainer (02:04):

So real quick, we're going to do a little mini topic on downstream injection versus upstream injection. Uh, one of the questions a lot of guys like to ask is, "how are you applying soap?" Well, the most common way of applying soap in the industry is a downstream injector. On this side, we're using a 2.1 fixture, all downstream injector. In theory, this size of this machine should give us roughly a 10 to one mix on the surface. This is called downstream because there's downstream of the high pressure pump. You have our high pressure pump, you have all the fittings. And then after that, we have our quick disconnect that ends the high pressure pump and would start our hose. Downstream injection goes anywhere after the unloader all the way to the gun. So whether it's an X jet and M jet M five twist with a downstream injector downstream injector with the J rod downstream injector with just a low pressure tip, all of that is downstream injection.

Josh Wagner - Power Wash Trainer (02:51):

The only time upstream injection comes into play is when you're inserting a soapy solution before the pump head itself. This usually comes into play when you're off of a tank. Um, it's very popular on the Quadro series made by Kranzle. It's very popular on older, larger, hot water skids, where they have their own built in, uh, not only soap reservoir, but also built in, uh, what do you want to call that, uh, basically float tank, uh, for when there's not enough water coming out of the spicket and you need basically that built in reservoir. High pressure soap, it's very handy for doing things inside of a industrial atmosphere. When you're doing something like cleaning a commercial kitchen, downstream injection, it is a much more effective way of applying soap in my opinion. But more importantly, the soap never actually entered your high pressure pump, leaving you all kinds of reasons to say why it is a better soap injection method versus the upstream injection. So again, for house wash and most of the time we're talking about downstream injection. All right, so what we have again, I a 4 gallon a minute machine, downstream injector, a hundred foot of high pressure hose plugged into our house wash mix. We are going to soap everything up, starting with our concrete sidewalk, going all the way around, give that the most dwell time. That's why we're starting with that. And then we'll start at the foundation, go up to the top and then hit the gutter line and we'll see how far we get

Using a j-rod with your pressure washer

Josh Wagner - Power Wash Trainer (04:31):

All right. So what we did is on our J Rod, we switched from a low pressure tip to a high pressure tip. The reason we did that is on a low pressure I'm going to draw soap almost the entire time, but what I wanted to do was switch to high pressure, you saw me spraying it against the brick wall. I was basically letting all the soap run out of our a hundred foot line. Now we have just fresh water and no suds anywhere. I'm not drawing anything. What we're going to do is hit all the glass and then we're going to hit the wood trim work on our door itself. Remember I said, we're going to take some time, basically make a delicate right there. That's what we're going to do real quick and just make it so that again, chemical, isn't the first thing that's touching this and that it's going to be water

Josh Wagner - Power Wash Trainer (05:17):

[inaudible] [inaudible] [inaudible] [inaudible] [inaudible] [inaudible] [inaudible]

Josh Wagner - Power Wash Trainer (06:21):

All right. So basically what we did was we took our soap. We laid it all over our sidewalk. In a second. We're going to walk around and see how that's doing. Just treating again, all the organic growth on the sidewalk and that lower stairwell. The next thing we did was we switched over to a high pressure tip so that we could rinse out our a hundred foot high pressure hose restricting us from drawing soap, and basically letting us put fresh water on the surface. After we got to that point, we wet down our glass, basically our windows, and then we spent some extra attention on the trim work, hitting that with water, so that as we followed up, switching back that low pressure tip, allowing us to draw soap. As we followed up with a soap solution, basically it wasn't too chemically strong for the wood trim.

Josh Wagner - Power Wash Trainer (07:02):

Everything is decorative all around the front of the house. If we focus a little bit on the gutter line, you can see what was there. Originally, all those black dots, all the algae that was growing all of the runoff from the top of the roof, it basically has gone away with our mix because our mix was even, that's a very mild setup. It's a very effective setup and solution. If we look at our sidewalk, basically our sodium hypochlorite is starting to work there. Wasn't a whole lot of, uh, carbon buildup. There wasn't a lot of grease on here. So the only thing that's really mattering right now is the fact that we got that organic solution on the surface. It's cleaning everything up. We're going to hit our stairwell a couple more times, just cause that was real bad back there. Well, maybe hit this one more time before we move on, this is going to be one of the last surfaces that we touch up with our surface cleaner When we're done, we want to get the solution onto the surface and let it sit for as long as possible, giving it the longest dwell time. So we're going to go ahead and fire it back up. This has been sitting for approximately two minutes. The first thing I would do is hit the glass. I'm gonna hit the wood. Then we had the plastic around the, a stairwell right there and I'll give everything a good, low pressure rinse.
