How do I clean salt off of my car?

I thought salt didn't work too well as a de-icer under -10 degrees, as it only lowers the freezing point of water to that temp? It seems strange that they use it in really cold places if that's the case.

Thanks for the tips m8s. I'll go and try them. Unfortunately, I live in a place where they don't oil cars. After I wash the car, I'll check and see if they do any anti-rust treatement around here.

Every winter I put my car in a thick layer of carwax...
