The answer to 'why is my pressure washer dusty' is that a dusty pressure washer is often caused by a clogged air filter or intake. Over time, the air filter can become blocked with dust, debris, and other contaminants, preventing proper airflow and causing the pressure washer to become dusty. This can also lead to reduced performance and efficiency.
To address a dusty pressure washer, you should first check the air filter and clean or replace it if necessary. Additionally, make sure the pressure washer is stored in a clean, dry environment when not in use to prevent dust and dirt from accumulating.
