How often should I wash a vehicle exposed to salt?

AAA recommends washing at least every two weeks during road-salt exposure and more often after heavy exposure.

Should a salt-removal wash include the undercarriage?

Yes. AAA recommends an underbody spray because salt can collect on parts beneath the vehicle.
