Much like a motorist would like to keep their vehicle clean and up to legal road standards, so should someone who owns a pressure washer. After all they’re both powered by fuel and an engine. It’s important to keep in mind that the pressure washer gets dirty very quickly and easily.
In terms of performance in order to keep it to running optimumly, cleaning it is a must as you could find many common issues such as the metals rusting away with time, tubes and pipes being clogged up with particulates, over heating of the engine and just general grogginess of operation.
Keeping all of these facts in mind, you can begin the clean by giving the surface of the washer (including the engine) a wipe down with a damp cloth and a micro fibre. Afterwards you can progress to checking for damage and oxidisation of the fixings such as any nuts, bolts or screws lubricating them or replacing any that are un useable.
After this you should check to see the condition of the wheels and if they’re rolling smoothly. If not, you should attempt to put oil or lubricant on to the bearings or outright replace them. You should also test the oil and perform an oil change if needs be aswell as refuel.
