I agree you need pressure, my car is all painted black underneath so sand is easy to see, garden hose simply does not remove all traces of sand, high pressure water does, but I use a water blaster with much more power than the local car wash places have.

Pressure washing the body paintwork is also much better IMO, as you can easy remove heaps more of the dried on abrasive salt/sand spray before you even go near it with a sponge and soap, hose pressure does not remove much of anything, the less you rub contaminates over paint the better.

This came up a while back about the car wash at Rainbow Beach, with some guy saying they use recycled water on the cars, as this is a wash I use/have used, I was interested to find out if that was the case, so i did some research and actually ended up speaking to the owner, while they do recycle some water for back flushing/driveway cleaning etc, the water going on your car is fresh water NOT recycled, and he pays a hefty bill for the water consumption.
