As a fellow cheesehead, don't drive on Wisconsin roads when they are wet. You'd think the salt would be washed away by June, but it's not. That salt compounds the problem immensely.Wash it down with clean water, and get it dry if you do. Shop-vac with a blower and a long hose to get it dry. If you're on a budget, old drained motor oil works good, make sure get it in the nooks and crannies. That leaves a smell though.
