The answer to 'how to clean pressure washer yourself' is to follow a regular maintenance routine to keep your pressure washer in top working condition. This includes cleaning the nozzle, hose, and other components after each use, as well as performing more thorough cleanings and inspections on a periodic basis.
Start by disconnecting the pressure washer from its power source and water supply. Use a soft-bristle brush or cloth to gently scrub the nozzle, wand, and hose, removing any dirt, debris, or mineral buildup. Rinse these components thoroughly with clean water. Inspect the hose for any cracks or wear, and replace it if necessary. Finally, check the pump oil level and top it up if needed, following the manufacturer's recommendations.
