For people in the south or the west, the thought of using salt on the roads seems ridiculous. Why in the world would the food additive get tossed down on the road during a snowstorm? But if you live in the east or the north, you know it is a necessity to winter time. And unfortunately, there are some consequences of using salt on the roads and you vehicle can end up paying the price.
The salt on the roads isn’t simply table salt. It is industrial grade calcium carbonate that is in bigger chunks and pebbles. The salt is spread over the roads when the sun will be out or the temperature reaches more than 15 to 20 degrees outside. The salt works in two ways in this instance. The salt makes a chemical reaction with the snow and the sun to melt ice and the snow. If the snow is not melting, then the salt chunks will also give a small measure of traction on the road.
Salt can also be made in to a liquid from that trucks can spray down before a storm hits to prevent ice from developing in the first place. This technology has improved road conditions tremendously for those who have to go out and drive, no matter what. But the technology comes at a price, to the cars, unfortunately.
Salt is hard on the undercarriage of a vehicle. The salt reacts with the metal and it can advance the rusting or decay of the metal. Cars twenty and thirty years ago didn’t have as much protective coatings to use on the bottom side, so they rusted out a lot faster than they do now. But it is still important to keep your vehicle cleaned and washed in the winter months to prevent the salt buildup. Salt can also get in to the engine, up in the air filters and generally cause havoc inside of the engine too if it isn’t cleaned and kept free from the particles between storms.
