What To Look For in a Pressure Washer for Your Car
For jobs around the home, an electric mains-powered pressure washer will be sufficiently powerful. There’s no need to use a petrol pressure washer for cleaning the car
There are also battery-powered pressure washers on the market, but I haven’t included them in this list because they lack the power of mains-powered models. For cleaning the car, you’ll want a mains-powered washer.
For light or medium jobs, choose a max pressure of 90 – 120 bar and a flow rate of around 330 L/hour. In fact, when it comes to cleaning the car, you might occasionally want to use a lower pressure of around 80 bar. This will still clean well, without risking damaging the paintwork. Look for a machine with a dial to increase and decrease the pressure, or at least an adjustable spray wand.
To tackle heavy-duty jobs, I recommend a washer with a bar pressure of around 130. This will be sufficient for jobs like cleaning decking, concrete, and patios.
Look out for additional accessories if you want a more versatile tool. For example, angled lances can help with clearing gutters and different nozzles can offer more spray variation. The best pressure washers for your car will have a range of compatible accessories available, meaning additional tools can be purchased at a later date if necessary.
Of the five models we tested, the Kärcher K2 Power Control High-Pressure Washer came out on top. It’s suitably powerful for cleaning the car, as well as other tasks, with 110 bar pressure. It’s hugely versatile, with numerous attachments included; plus, it can be used with warm water up to 40°C, which is useful for tackling more stubborn grime.
