Just for everyone's knowledge base, salt on the roads does not cause corrosion. Water causes corrosion. Salt draws moisture and holds it. Salt stuck in nooks and crannies is the worst. This allows the water to do its dirty work.
Rinse away the salty water and it will dry quicker, reducing the chance for corrosion to fester.
Salty water also increases galvanic corrosion by making the ion "hand off" to happen more easily.
Winter driving ok with frequent thorough rinses.
