I live in MD, and no matter where I drive, if it has snowed, I get my car dirty because the salt trucks come out diagonally across from my house, which means when I drive to the main road, there is always salt. New salt. So my car gets pretty dirty in the winter. I wash it when it gets too dirty, but as little as possible because it'll just get dirty again and I feel my energy is wasted if I do it too frequently
yes, salt kills your car. We dont have salted roads here in the winter They spray a chemical that keeps the roads from getting icy. That makes a mess out of your windows. It there is any road spray, your windows just blur and it smears everywhere. It makes it very hard to drive some days.
They don't salt the roads too often here. They're more likely to spread sand and gravel on the main roads. That makes our car a mess but if we wash it in the middle of winter, it will just get dirty again. We wash it at the end of the snowy season here.
