Cleaning your high pressure washer is not just about cleaning the surfaces; it’s about maintaining its internal components as well.

4.1 Clean the Pump


The pump is the heart of your high pressure washer. Regularly flush it with clean water to remove any dirt or residue that may accumulate over time.

4.2 Rinse the Nozzle


After each use, rinse the nozzle with clean water to prevent clogs caused by leftover detergent or debris.
