Getting paint off garage floor

Hello, I’m trying to remove paint that the previous homeowner left on the garage floor. It looks like they used a sprayer. I have a 3800/2.4 pressure washer but it’s not doing a great job, really taking forever to get even a small area complete. Any tips? Also any tip on what color nozzle I should be using? Thanks!

How do I clean black water stain off white siding?

I'm helping clean the siding of a church with vinyl. This black stain appears to be from the roof with rain runoff. I've tried the vinyl siding spray cleaner, which does a good job on mold and dirt in general. However, it isn't really working on this. I've also tried mixing water with LA Totally Awesome cleaner (more than 50/50 mix of cleaner), as well as Purple Power. I use a scrub brush on an extension pole, and it does help fade it some. However, it is still there and obvious. Are there any better options for this? Should I try 100% cleaner vs mixed with water?

**Hurricane Helene took off the added roof they had built, and the contractor just repaired the older trailer-style roof that was originally under that. I don't know why, or the history, but now it causes this water staining issue. We are in the process of painting the deck as well.

Dumpster Pads?

I’m looking to start doing dumpster pads

To test the market and stack enough cash to buy my own commercial rig, I’m planning on renting a hot-water pressure washer from a local yard to handle my first few route days.(4gpm hotsy trailer)

My exact math for a single rental day looks like this:

Fixed Overhead (Rental + Pickup/Drop-off): ~$220/day

Chemicals : ~$20 per pad (budgeting 1 full gallon per ~200 sq. ft. pad)

My goal is to walk away with $500 in pure profit per day to make the physical labor and rental hassle worth it. To hit that, I am aiming for route density—batching 4 pads on the same block or strip mall at $200 each ($800 total revenue minus $300 in rental/chem costs).

For the guys who have done this: Is it realistic to knock out 4 nasty restaurant dumpster pads in a single day using a rented machine, or will setup, breakdown, water source headaches, and rental return times kill my schedule? Is renting a smart bridge to validate the route, or should I just buy a machine upfront?

Anybody in around cypress or katy have a good recommendation for exterior house cleaning?

not looking for the cheapest guy with a pressure washer trailer, mainly want somebody reliable that won’t damage siding or leave streaks everywhere. we’ve got algae buildup on one side of the house and the driveway is getting pretty dark too.

would rather hear from people who actually used a local company recently. who’d you recommend?

Oxidation ?

One day after soft wash using Krud Kutter Housr and siding. Customer believes I stripped the siding. Looks like oxidation being more noticeable after a wash. I’m pretty new just side hustling.

Window Spots After Soft Wash

I have a clients that’s pretty upset about this spotting on their windows. I’ve been getting some complaints about this happening. Not sure what to do to prevent it besides rinsing after (which I do). Also how to explain to client who is upset with this.

Hardie board oxidation?

Customer would like their house soft washed. My question is whether or not this hardie board is oxidized. The shiny section in the photo is where I rubbed my hand over it. It also left a dark residue on my fingers. I told the customer there may be oxidation and that a soft washed will not fix this. Should I walk away? What problems could happen if I do a soft wash?

External bypass hose keeps blowing off on AR XRV 4G.32 pump, bad unloader?

I have an older pressure washer with an Annovi Reverberi XRV 4G.32 pump rated 4 GPM / 3200 PSI / 3400 RPM.

The small external bypass/return hose from the unloader keeps failing. I have replaced the hose multiple times. Sometimes it blows off the barb fitting, and other times it gets a hole and sprays water. I tried turning the pressure knob all the way down, starting the machine while holding the spray gun trigger open, and slowly increasing pressure, but the hose still blew off again.

If you can help please lmk

Somebody diagnose this issue

Was running fine until this started, it eventually was running fine afterward and I got the job done. Weird, no idea why it was doing that though it is a old ass motor

Skid ideas.

Ah I’m on the fence about building a skid in the back of my truck. Starting to get a lot busier these days. Where I’m from I can only pressure wash for about 5 months. If I build my skid in the bed of my truck I’d have no way of taking the skid out as I don’t have a forklift or anywhere to store it. But I definitely need something as I can’t have all my equipment flopping around the back of my truck.

Is this machine worth buying?

Good morning. My company manages several office buildings, parking garages, etc. in a small town. We occasionally need something pressure washed (cleaning stained sidewalks, parking areas, parking garage and ramps, graffiti, etc.) and have mostly just paid someone to come in and do it for us. I just saw this machine on sale through home depot and was wondering if it would be good enough to do the basic things I've described. Here's the unit: https://www.homedepot.com/p/Briggs-Stratton-3200-MAX-PSI-4-5-MAX-GPM-Gas-Pressure-Washer-with-Project-Selector-Powerful-208-CC-Engine-022020/331012048

thanks in advance!

Pressure washing a travertine patio

I have done A LOT of paver restoration jobs on traditional pavers but this stone is new to me. From what I’ve read online, one shouldn’t use a turbo nozzle on it because it will damage. So I’m wondering how I would remove all the weeds and grass from the gaps without using high pressure? This is only a small sample area of a huuuuge pool surround and patio.

Additionally, I normally do polymeric sand after cleaning but these stones have so many pits and imperfections idk if I should use that. Any advice?

Harbor freight 4gpm

So, I have been recommending the harbor freight 4gpm. I've used one for about 4 years on and off. I'm pretty sure u/imnumber1 pointed out that HF started putting cheap Chinese pumps on these, rather than the AR pumps. I used my warranty on one in March of this year and it came with the AR pump and a decent hose.

That washer had very little use from March until this week, under 10 hours. It got water in the cylinder during that time. It lives on my trailer, uncovered. I changed the oil and thought it was a fluke. I went to fire it up the other day and water was in the cylinder again. Not the oil, not the fuel, the cylinder. The engine was hydro locked.

I returned that one for a new one, and to be honest I had to drive 45 minutes to find one, the 4 stores local to me had none. This new one has the Chinese pump and the stiff, slick hose.

All this to say, I'm not sure if recommend them anymore. For $750 + $300 warranty it's still probably the best financial deal, but I'm not sure it's worth the fuss of returning a poorly manufactured washer.

When it comes to the pressure washing business what is the biggest problems that arise when it comes to clients and handling them.

I’ve been thinking about getting deeper into the pressure washing business, and one thing I keep hearing is that dealing with clients can either make the business easy or turn it into a headache fast. For the people already running pressure washing companies, what are the biggest problems you run into when handling customers?

Is it mainly things like unrealistic expectations, late payments, constant rescheduling, people trying to negotiate prices, complaints after the job, or just communication in general? I’m also curious about how you personally deal with difficult clients without hurting your reputation or losing future referrals.

What situations have caused you the most stress, and what systems or lessons helped you fix them?
