Is it safe when cleaning your car to use a pressure washer on the wheels or can it affect the discs/calipers? I usually do my wheels by hand but it takes ages with the multispokes on my new scoob!! Id only use the pressure washer to loosen the grime slightly then to wash off the wheel cleaner, so wont be sticking the nozzle right in and going hell for leather.

 

Not a problem to use a washer. Discs will go a rusty colour but will clean up once you use the car
