Hello, I downstreamed this vinyl siding house the other day and got a call back that there are these lines all around the house.
I have a 2.5pm pressure washer. I downstreamed it let it dwell and I don’t think I rinsed long enough. I rinsed enough to clear the chemical. It’s about a small ranch type home and I rinsed maybe 30 seconds to a minute probably per side.
I’m pretty sure this is the cause of this just want another opinion? Also how do I fix this, should I downstream it again, dwell, and then rinse it very thoroughly?
Share with us more details about your process and paint us a better picture: What did you downstream, how long did it dwell, did it dry, was it just this one side, air temperature outside, etc.
It was a hot day about 80+ degrees. Started the work in the afternoon like 12 or 1pm.
Just downstreamed SH & soap. Used the 12.5% SH but it get diluted when the downstream injector comes into play.
Let it dwell about 10 minutes or so I would say. Don’t think it dried, it was all sides he was saying that had these lines, the front left back right.
Previously I asked for help on a topic that had white spots leftover and was advised to let the SH dwell a bit longer so I haven’t made that mistake since then…
Process I pre wet most plants and then applied the SH batch mix all around the house, let it dwell, then went to rinse it off. But like I said I think I just rinsed too fast.
Pressure washing 101 - 70% of your time is spent rinsing. You can’t rinse a dog house adequately in 1 min with a 2.3. Hard to tell from pic but it looks like dirty water dried on it. Do you have any better pics, like from further away.
Reclean with a weak mix. It’s dried now, just water may not break it loose. Take before and after pics and don’t leave a job again with it looking like that.
It sucks cause I also cleaned the windows and will have to redo the outsides. Window cleaning is my specialty, soft washing not so much… but I am getting there.
Don’t take this as snarky, but seriously after soaping you will get a whole lot more rinsing power just using their garden hose and a good distance nozzle. 2.5gpm is about what my kitchen sink puts out, a typical outdoor spigot belts out at least 5.
Just a thought until you get that snazzy 8gpm machine.
This is a pic, used it many times to blast off pine needles from glass enclosure patios.
Is there an 8GPM or 5.5 machine you can recommend.
I have / used the 4 GPM dewalt pressure washer but that thing is a nightmare it’s hard to turn on and leaks a bit so I have to get a better setup soon.
Sometimes I hear you guy say 8GPM or 5.5 but is that just like a 8GPM pressure washer?
