lines on vinyle siding?

hey guys im new to this and so far its been good and alot of learning on the way but last week i done a vinyle house and today i go by there and there are lines/strips on the siding how do i fix it?? what caused it?? i used a pressure pro 8gpw hot water with a jrod down streamer and washed it with the big hole end 0020 i think i would have to look but i down streamed 12.5 sh with elemonator help please and thanks i tryed to take a picture but you couldnt see the lines in the picture
 
We'd really need pictures to give you a good answer... But it could be oxidation... could be maybe you hit with a bit too much pressure... Maybe you didn't rinse thoroughly... Maybe weep holes that leaked and dried leaving discoloration... Try again to get us a pic, or at least try and explain the lines a little more and we may be able to help you out a little more

this is a picture i found on google its not that bad but thats what it looks like and about the pressure part i can put my hand in front on the wand its the big orface on the jrod from pressure tek how can i fix it the customer didnt see it or say anything about it but i wanna fix it if i can or learn from it thanks
 
Yea, that's an oxidation issue. the "lines" as you call them are the places where you got too close with the washer,..they are actually the really clean spots.

0020 nozzle would be the rinse nozzle, and not the "big hole" nozzle,...your big nozzle would be most likely a 0060 if you got Bob's J-rod setup.

Either way though,.sometimes oxidation will come off easier on some jobs than others,..manufacturer, age of siding, Sun exposer being a few things that can determine degree of oxidation.

Best way to fix it is go back and brush it with something like Purple Power, or whatever you gutter cleaner is,...and tie it together.
It will come back together on it's own over time,...you didn't damage the siding, but it's not aesthetically appealing.

Many topics here on oxidation and various ways it's dealt with. Darker colors are more challenging to deal with when there's alot of oxidation.

Shot in the dark on this one...

Could be HW mix that was applied and allowed to dry and or not rinsed well enough. On warmer days, if HW mix is applied top down without pre wetting, you get flash drying. You could try washing/rinsing again. I'm sure others will chime in. Good luck bro...
 
If it look like the pic, then plain and simple to much, and inconsistent pressure in those areas, and you removed oxidation (chalk). You should have rinsed using a garden hose or open ball valve and stayed way off the surface.
 
A variance of Dougs point,...Until you get used to the impact of the 0020,..use the 0060 for rinsing,...when you're ready to rinse, simply pull the DS hose out of the bucket.

BTW,..I made one of the DS by-pass contraptions,...I really like it. Not sure the exact name.

Part or most of the problem is the 0020 nozzle, should not be used on vinyl, wood, aluminum, etc..... just too much pressure.

Do some reading or ask for help if you are not sure of what nozzles to use.

Don't use hot water on vinyl, if your machine has a problem you can melt the vinyl fast and easy and that would be an expensive mistake.

DS by-pass contraption. That's good a name as any. I will never go without one now.
 
I agree Ralph,..I used Pat Normans modified version,..with the full flow being the straight path, and the DS through the curve. Just for the sake of it, for next year, I may make another one using 1/2" fittings and hose,..to open the flow through the 90 degrees better. Might not even make a difference, I don't know.

But yes, turning the soap off and being able to run soap nozzles without having to pull the soap injector out and sucking air and running full volume is a big plus.

Hook up the surface cleaner and turn the valve to full flow,..no shutting down.

Why not just have a bucket of clean water and drop the hose in it. Seems to me it would be faster and not have to build something.

I do it because you are still bypassing flow even if you put it in a bucket of water. I am using a 2-3 gpm injector so i get a lot of soap. I can just tell when using my surface cleaner that I am losing flow with the injector on.

I find it faster with the bypass. No bucket has to be there, no SH getting all over the place. Just turn the ball valve and you got full flow and can use a rinse nozzle. I used to use the water bucket too Doug. But I can hear it in the engine, and the unloader, that there is a load on and the unloader is bypassing.

Hey Doug,..sure you can do it that way. Rinsing with full flow can be beneficial or at least preferred by some. Or you can do as my helper did,..lay the DS hose on the top of the bucket so it pinches it shut,..that worked also.

I didn't "have" to build it,..I enjoyed every second of it,..I love building things for my work. Just easier and faster to turn the valve and shut the soap off. Some see the benefit some don't.

And the flow does make a difference when running a surface cleaner,..no doubt about it. And not having to shut down to remove the injector is a plus.

"Contraption" probably isn't a good description,..as "contraption" gives you visions of many moving parts going every which-a-way,.Ha,Ha,..

Only one moving part, the HIGH PRESSURE ball valve. You soap injector is a part of it, and the whole unit connects inline,..very simple concept.

The purpose is to be able to simply turn a valve for soap and back the the other way for full flow rinse, or running a surface cleaner without removing the soap injector.

NO,.it's not a game changer by any means,..but for some it does make the job just a little more convenient.

*Not always used when rinsing,..but very nice when you're in a porch area or other close quarter rinsing where lower pressure is desired.

Like any tool, it has it's place for some, and for some it doesn't.

The difference in flow with the bypass is just unbelievable to me. I always use the widest fan tip I can. I only use the 0050 for soaping way up high and an 0040 for rinsing high. An 0020 with 8gpm could surely leave "Zorro" marks on oxidized vinyl. You may need to try brushing with some butyl or something to even it out.
