If you’ve ever tried scrubbing a driveway with a stiff brush, you’ll know it’s hard graft. That’s where a pressure washer comes in – making light work of tough cleaning jobs with the power of high-pressure water. Whether you’re freshening up your patio, cleaning down tools, or preparing a surface for treatment, it’s a tool that delivers fast, effective results with minimal effort.
Used properly, a power washer can save you hours of work and achieve a finish that’s hard to beat, but there’s a right way to go about it. In this guide, we’ll break down the basics of using a pressure washer safely and effectively. We’ll cover what they’re good for, clear up a few common myths, and explain the differences between models so you can choose the right one for the job.
What Pressure Washers Are Good For
If you're tackling a weekend garden project or cleaning up after heavy site work, the right pressure washer can make the job faster, cleaner, and more satisfying.
Here are just a few of the jobs they’re perfect for:
- Driveways and patios: Remove moss, algae, and ingrained dirt from stone, concrete, and block paving.
- Decking and timber: Clean off mildew, dirt, or old coatings (just be sure to use the right pressure to avoid damage).
- Garden furniture: Restore wood, plastic, or metal furniture that’s been left out over winter.
- Fences and sheds: Wash away years of grime before treating or painting.
- Brickwork and external walls: Remove pollution stains, algae or old paint – ideal before rendering or repointing.
- Tools and plant equipment: Clean off cement, mud, or grease quickly and thoroughly.
- Vehicles: Suitable for vans, bikes, and even cars – but stick to low pressure settings and the right attachments to avoid damage.
Top Tip: Always check the surface you’re cleaning can withstand pressure washing. Delicate materials, loose pointing, or flaky paintwork can be easily damaged if you go in too hard.
Common Pressure Washing Misconceptions
Pressure washers might seem straightforward: connect the hose, press the trigger, and blast away. But like any powerful tool, there’s a bit more to it if you want to get the best results and avoid damaging the surface you’re working on.
“The higher the pressure, the better.”
Not always. It’s easy to assume that more power means better cleaning, but too much pressure can damage softer surfaces like wood, mortar, or painted finishes. The key is using the right pressure and nozzle for the task – sometimes, less really is more.
“You can use any detergent.”
Pressure washers require specific cleaning solutions designed for the machine and the task at hand. Using standard household cleaners can damage the internal parts or leave residues that affect performance. Always check the manufacturer’s recommendations, or ask us in branch if you’re unsure.
“You can’t do any real damage.”
This is where many first-time users go wrong. Pressure washers can strip paint, gouge wood, and even shatter glass if used carelessly. It’s not about brute force, it’s about control, distance, and using the correct setting for the surface.
“A pressure washer is a pressure washer.”
There’s no such thing as a one-size-fits-all model. From compact electric washers ideal for patios and furniture, to petrol-powered units for heavy-duty site work, each is designed with different jobs in mind. Choosing the right type will give you a better result and a much easier time doing the job.
Choosing the Right Pressure Washer
The right model of pressure washer can make your job much easier, while the wrong one can leave you frustrated, or worse, with a job half-finished. Whether you’re cleaning a patio, prepping a building for treatment, or blasting years of grime off tools, it’s worth knowing what to look for before you buy or hire.
Electric vs Petrol Pressure Washers
Electric Pressure Washers
Ideal for domestic use. They’re quieter, lighter, and perfect for tasks like cleaning patios, cars, and garden furniture. Most plug straight into a standard socket and are easy to store.
Petrol Pressure Washers
These are the workhorses. Best for large-scale or heavy-duty cleaning jobs. They’re more powerful, don’t need to be plugged in, and can handle bigger areas, stubborn grime, and regular use on site.
Key Features to Consider
- Bar Rating (Pressure)
Measured in ‘bar’, this tells you how forcefully the water comes out.
100–130 bar: light-duty (home and garden)
130–150 bar: medium-duty (larger patios, driveways)
150+ bar: heavy-duty (trade, industrial use) - LPM (Litres Per Minute)
More water flow means faster coverage – useful for large areas or stubborn dirt. - Nozzle Attachments
Look for models with variable nozzles or interchangeable heads. A fan nozzle is ideal for broad surfaces, while a pencil jet offers more concentrated cleaning. Turbo or rotary nozzles combine pressure and rotation for deeper cleaning. - Hose Length and Reach
A longer hose gives you more freedom to move around without shifting the whole unit, handy on large driveways or building sites. - Detergent Tank or Feed
Some models include a built-in tank or suction hose to add detergent, helpful for oily stains or mildew-prone areas.
