How to drive my 2007 Yaris forever - Toyota Yaris Forums

I have a silly question. I live in one of those mild winter climates. We can have freezing rain or five inches of snow one day, and then a few days later it warms up to 40 degrees. Oftentimes, on those mild days following a deep freeze, it rains. I avoid driving when the roads are salted as much as possible. I take the city bus to work and I live within walking distance of a grocery store, so I have the luxury of choosing not to drive if I don't want to. However, there have been a couple of times this year when I did have to drive on a freshly-salted highway. When that happened, I would take a long highway drive during the next big rainstorm, with the idea that the heavy rain would wash all the salt off the undercarriage. Would this actually work? Is driving in the rain a good way to clean off the undercarriage and prevent rust, or does it not actually do anything?
