I wash them during the winter when I can't stand to look at them that dirty any longer. The Ranger has been washed twice this winter, the ION will be washed on Sunday. So far as not washing because the salt will go places it wouldn't otherwise is a load of S..., it goes to those places just as bad on the highway following a truck as it would by washing it.
+1 there. I have no idea where some of you guys are getting your crazy ideas from? Not washing because you're afraid the water will carry the salt to places it wouldn't go? That makes no sense to me whatsoever. But hey, it's your car(s) and you guys do what you want. I just bought a new car (took delivery Oct 23rd) - have had nothing done to it yet though I did put weathertech floor liners in her (both front and back). I wash it approx. once / week. I don't want that crude on my car, seeping into those places you guys don't want it too when it warms up and I'm driving in slop and getting wet salt and sand sprayed all over my car anyway. I take it to the auto spa where they do a hand wash and towel job when I can, if not I take it to a touchless laser wash. Idea here is to keep the salt / sand from getting in those nooks and crannies, and it definitely will if you 'never' wash it in the winter time.
Besides, with all that crude on it, one person rubs up against it and then you get to spend a few hours working your butt off getting those scratches out of the paint in the spring.
Man, never - good luck with that one
