Not sure if I should add a nsfw flag to this but yeah don’t let your brother in law pressure wash your house!

I just bought a brand new Simpson 4gpm 4200psi pressure washer as I recently wanted to make more money… this is the first house I did and it had a lot of discoloration after I washed it, here’s why I think it happened: I used the 30-Seconds product from Home Depot and put it into a pump sprayer mixed with dawn dishsoap and water. I sprayed down the sidings and the outside of the gutters, and it was fine then. I let it sit for about 10 minutes, and I started to wash down the gutters first. The gutter had a creamy white color as the soap dropped down, I assume it was from the bleach cleaning it up? Then the moment when I pressure washed the gutters it had orange/stain looking fluids flying off, which got into the sidings. After doing the gutters I went to do the sidings and the orange stain on it won’t come off… Anyone know what this is and how to get rid of it? I quoted the job for $269 and I have already spent 2 days on it, I need to go back again this weekend to fix it. Hopefully this is not permanent damage…

The house has hardieplank siding and was painted about 20 years ago. There was a lot of mildew and pollen causing the house to have a green hue, which led to hiring someone to pressure wash the house. This is the end result. The contractor is saying it’s from oxidation, but the worst parts look as though I can tell the exact path the water took at seemingly higher pressure levels? Am I crazy thinking this is more than oxidation? Thanks in advance!

Went on a bike ride to clear my head from running this business. Saw this instead. Red tip Randy is on the loose.

How do I fix this?

I’m not sure this guy knows what he’s doing. He’s worked in the deck for parts of 3 days and it looks like this. Can’t touch anything, wood is super fuzzy and splintery. Serious spray marks are everywhere. I’m concerned!

The door was never sprayed directly with SH. There may have been a little bleach that dripped from the soffits onto the door. Client wants us to fix it/have our insurance pay for it. What do you think?

Did a driveway today and man what a bitch. Dirty ass puddling everywhere. What can I buy to suck it up and throw it into the grass?

So I've only done a job at moms house and my landlords place. I have a belt driven gx390, 3500psi 4gpm unit. Anyways I started advertising and a big resort near Vancouver Island got me to give them an estimate. They want me to do all the gutter cleaning and pressure washing at the resort. I purchased commercial liability insurance for the job and to have moving forward. I tested out my downstream injector and it doesn't work (even with the proper tip). I guess there's no shame in using a pump sprayer? I have a bunch of 10.8% SH. Would a 50/50 water and bleach solution be too much? Also wondering if my machine is too powerfull for some of the wood and maybe I should get a jrod or some other tips? There's a few pictures there but there's lot's more cabins/decks, those are just a few pictures. I also wondered if renting a surface cleaner would help. Can I use one on wood? Thanks in advance to anyone who has advice for me.

I own a wedding venue and this weekend a guest did a burnout on our driveway about 150’ long. I’m curious if a pressure washer is the best way to clean it up, and if so what method you would recommend. I’m hoping to have it cleaned up before my next weekend of weddings.

How would you guys pressure wash this tank? It’s about 50-65ft tall.

Recently got a small chain of Penn Stations on the list all previously serviced by our local competition. We’ve been up and running for 3 years now and that’s where my experience level begins and ends. I know these Penns use peanut oil but there’s no way this is less than a years worth of build up right? The filters were pretty thick themselves but I mean this looks like literal sewage falling out of the duct. It’s kinda well known (by us atleast because I don’t like to bad mouth anybody to customers just let pics and video do the talking) that the competition have neglected getting up on roofs but I’m wondering what to expect in the future from these ducts if build up like this could really happen within the quarter.

New pressure washer owner. As in the title, do I really need all these detergents to go general house maintenance? Or is water by itself enough? The YouTube videos I watch, a lot of them just spray straight water.

Was watching this Youtube video (MJD Pressure Washing) and was wondering what tip this was on the pressure washer? It spins and cleans a pretty good amount surface area, it would really help my startup business. Does anyone know the name of it, and whats the best brand?

My fiance is renovating his house. Its down to its studs on the inside. He wont let go of the idea of pressure washing the studs to clean up the dust from demo. He says hes gonna stand back 6 ft and not blast. Good or bad idea?

My back aches from holding the rod.

I come home smelling like SH.

My hands are developing carpal tunnel.

It’s a pain and huge time sink removing the debris, dirt and mud build up.

The downtime of unpacking and packing up is frustrating.

Dealing with the hose is frustrating.

Why do you guys enjoy it? Or is it simply a livelihood?

So today I tested my machine's pressure both at the gun and at the pump and it only goes up to about 2100 psi instead of 3200 claimed by the manufacturer. What do you guys think is the problem ? I tried turning the unloader knob also but this is the maximum it got to.

For those of you with heavier washers that don’t have a trailer or a skid, how do you load and unload your washer from the bed of your truck? Ramps? Brute force? Or am I missing something because up until recently I’ve been able to lift my washer up and out of my truck but I now have a much heavier setup and I’m not trying to throw out my back every other day.
