Seems like that salt stays there forever. At least now people can go thru an automatic car was and get the bottom sprayed off. Then we have brine that eats at the car instantly. Good for brake parts companies!
With salt stuck under old vehicles and condensation/humidty, it can continually work on cars in barns.
Friend of mine had a guy bring him a Blazer that had been driven on the beach. That truck had rust in weird places until we saw sand falling out of it. I doubt anyone bothered to try and rinse it out

That car won't be restored. It'll be parted out on eBay...........

Is it better to leave newer cars outside after it has been in the salt driving due to the cold

stopping the rust effect, or put away in garage without rinse with water? What does the

warmth of the heated garage due to cars after they have been driven in the ice and snow?

Not just salt's the problem as winter washing and other wetness/moisture caught inside seams/welds etc can freeze/expand countless times throughout a winter season of above/below freezing temps w/ gap between growing larger each cycle.
More concerning than sightly rust may be today's unibody cars which although they passed structural strength crash tests when new, may not after 10 or whatever years of normal driving use in the rust belt?:hmmm:
