No, don't use desiccant to remove moisture from the components, especially not something corrosive like table salt. Most desiccants are likely not good enough to suck enough moisture out at room temperature, or it will take forever.
Just bake the parts using standard baking procedures (see Google). Using high enough temperature drives the moisture out in sensible time. The idea is to use lower-than-reflow temperature so that the parts won't crack from water evaporating too quickly; but high enough temperature so that the water is eventually (in a hour or two) forced out, through the plastic.
