In the world of Machinery cleaning, knowing your gear makes all the difference. Pressure is everything, too little and you’re just making things wet, too much and you might blast a panel off. Which is why EZWash, we don’t just rock up with a hose, we bring the right machine, the right pressure, temperature and the right mindset to get the job done right, always a "can do" attitude to get the job done right.
So let’s break it down: how machines work, why pressure control matters, and when it’s time to call in the 4,000 PSI workhorse… or unleash the 10,000 PSI beast (or more) when things get serious.
How These Machines Work (And Why It Matters)
Pressure washing gear is all about muscle and precision. It works by forcing water through a high-powered pump and out a narrow nozzle at serious speed, kind of like giving dirt a high-velocity eviction notice. The result? A powerful stream that cuts through grime, grease, dust, mud, and even hardened muck stuck to trucks, trailers, machinery, and heavy equipment.
But here’s the catch, it’s not all about maxing out the pressure. Every job’s different, and going too hard on the wrong surface can do more harm than good. That’s why regulating pressure is key.
So, what is pressure washing actually for?
✅ Cleaning trucks, diggers, trailers, and industrial equipment
✅ Blasting off road grime, caked-on mud, grease, or concrete
✅ Getting gear ready for inspections, resales, or relocations
✅ Making sure your machinery looks and runs like it should
And what’s it not for?
❌ Washing your dog ❌ Freshly painted items ❌ Giving your sneakers a “deep clean” ❌ Cleaning your mate’s ute… without asking
Why Pressure Control Is Critical:
Using the wrong pressure on a truck or piece of machinery can strip paint, blow seals, or damage delicate components or taking long time to do de job. On the flip side, not enough pressure just won’t cut it especially if we’re dealing with red dirt, road grime, or oil-stained underbodies.
That’s why our team always assesses the condition of your gear before touching the trigger. We tailor the pressure to the job, the temperature of the water, the manual work being to close or too far, so you get a proper kind of clean, without wrecking anything in the process and in the most efficient way.
Mid-Range Power: 4,000 to 10,000 PSI. The Industry Workhorse
This is where most of the heavy-duty cleaning happens. These machines are versatile, safe when handled correctly, and perfect for knocking out most commercial and industrial grime without breaking a sweat.
We use this pressure range for:
Surface Prep: Stripping away loose paint, rust, or concrete residue
Fleet Washing: Prime movers, rigids, refrigerated trailers, tippers, and more Degreasing: Engine bays, wheel hubs, chassis frames
Construction Equipment: Excavators, loaders, rollers, screens and bulldozers
Agricultural Equipment: Tractors, harvesters, and fertiliser spreaders
Mining Equipment Maintenance: Removing coal dust, red dirt, and lubricants
ESCADA & Quarantine Readiness: Ensuring compliance for inspections and relocations
At this range, you're getting a balance of power and control, ideal for most applications across transport, logistics, civil works, agricultural, and industrial maintenance.
Ultra-High Pressure: 10,000 PSI and Beyond. The Specialist’s Tool
Once you break into 10,000+ PSI territory, you’re in the world of ultra-high-pressure cleaning. This is not your everyday setup, it’s used for specialist applications where nothing else works.
These machines are ideal for:
Concrete Demolition & Surface Removal: It removes just the top layer of concrete, perfect for re-coating or resurfacing.
Bitumen and Tar Removal: It breaks the bond between bitumen and metal or concrete surfaces.
Heavy Mining Equipment: Cleaning undercarriages and removing mineral build-up
Marine & Offshore: Stripping rust and paint off ship hulls, tanks, and docks
Industrial Heat Exchangers & Pipework: Clearing blockages and scaling
Factory Floors & Workshop Bays: Deep removal of oils, chemicals, and embedded dirt
In sectors like mining, energy, defence, and civil infrastructure, ultra-high pressure is the go-to when deep cleaning must meet strict safety or regulatory standards. Some of these powerful units (20,000+ PSI) are massive machines that can't be mobile, used in industrial plants, shipyards, nuclear facilities, or pipeline servicing. They're too large, too power-hungry, and often need permanent infrastructure.
