Best Petrol Pressure Washer Reviews UK

If you are looking at doing some serious do-it-yourself power washing around the house, it’s time to look into getting yourself your own power washer. Lower-priced, consumer models have helped make power-washers available to anyone who needs one, on any sort of budget. But how do you know which is the best petrol pressure washer for you?

When looking at power-washers and deciding which model is right for you, the first choice you will have to make is between electric and petrol-powered models. Electric-powered power-washers are much cheaper and easier to use, but do not have nearly much as power as their petrol-powered counterparts. They are better suited for decks, patios, furniture, and smaller jobs where cleaning, rather than stain removal, is more important. They are much quieter, easier to use and control, and much smaller and lighter, which makes them easier to move and store.

The downside to electric washers is that they are much less powerful. This makes cleaning slower, and limits the kinds of tasks you can take on with it. Your mobility is also limited, as you need to be near a power source.

A petrol power washer, on the other hand, can easily have twice the power of an electric model. They can put out on average anywhere from 2000 to 2,800 PSI, though some models get into the 3000’s. Electric models usually put out between 1300 and 1700 PSI. That’s about 60 times the pressure put out by your garden hose, making them excellent, easy ways to power away mould, mildew, dirt and even driveway stains. They are better for washing siding, fences, and much larger projects than electric models, and work much faster than electric models. The downside to petrol models, of course, is that they are much larger, much heavier and harder to manoeuvre. Their sheer power makes them more efficient, but much harder to handle and use. They are also significantly louder, and harder to maintain. You will need to mix fuel properly, keep it properly tuned, and pump it with anti-freeze in the winter. There is also the danger of damaging vinyl siding and soft surfaces like wood, so proper care and technique must be taken when using petrol power-washers.​

What else to look for in a power-washer? Pay attention to the size of the washer, to make sure it’s a size and weight you can handle. Look for models with wheels, to make them easier to move. An added soap tank makes if far easier to mix soap and water and saves you extra hassle.

For our reviews of the best petrol pressure washers UK guide, we will solely focus on petrol-powered models. Below you’ll find some of the most popular and well-reviewed models on the market today.

Tips For Using Your Petrol Power Washer

Once you’ve picked the best petrol power washer and you’re ready to get to work, here are a few tips to keep in mind when using it, and a few pointers for safe storage and maintenance.

Pressure washer nozzles often use colour-codes to mark how powerful the spray pattern is: White is 40 degrees, green is 25 degrees, yellow is 15 degrees, and red is 0 degrees. Black nozzles are used for soap, and are quite low-pressure. It is best to use the lowest-pressure nozzle you can to achieve the results you need, as a higher-pressure nozzle may damage or mark the surface being cleaned. Always test a nozzle before using it. Spray it in a place no one will notice, before using it in a more conscious place. Hold it an angle and from a good distance; don’t just go full-on from the front. You may damage the surface.

When cleaning a vertical surface, start by washing in an upward direction, and then by rinsing down. Be careful not to spray water behind or under siding, doors, lights, etc. Water can easily damage surfaces behind these, and if they do not dry out properly, may result in the growth of mould and mildew in dark, closed spaces. Always keep the nozzle moving constantly as you wash, to prevent the water from damaging or cutting into the surface – especially on soft surfaces such as wood. It’s also recommended to use a pump preservative to store the machine over the winter, to protect the pump corrosion or freezing.
