As a experiment, when you car is really dirty, hose your paintwork with a low pressure garden hose for a hour and see what residual contaminates are still left, in comparison, hose your paintwork with a decent pressure washer and most of the time, it will be almost clean in 5 min, when you think about it, the same contaminates are all under your car (if not more) so unless you also get under the car and wash your underbody/chassis/diffs with a sponge then rinse, I cant really see how you are removing much of anything, low pressure hosing may eventually dilute the salt ,but does not really "clean" the underside of your car good enough IMO.
