The brine solution goes on wet but dries after contact.
So What is Brine? Brine is a mixture of salt and water and it's used in place of salt crystals on roads because it stays in place better. When rock salt crystals are spread on a road, a large percentage of them bounce and roll off to the side where they are of no help keeping the road free of ice and snow. But when those crystals are dissolved in water before they are spread, they stay on the road longer and increase the effectiveness.
Why is Brine Bad for Your Car? What makes brine so desirable as an ice fighting road treatment also makes it harder on your car. Brine not only stays in places on roads, but when kicked up by driving over pavement treated with it, it stays on the underside of your car too. Crystals of salt bounce of roads, and they also bounce off your car. But brine coats every nook and cranny on your vehicle's under body with two things that cause iron and steel to rust: water and salt. Either water or salt on their own are capable of causing rust of course, but the two combined are much more corrosive.
Brine Also Often Contains Magnesium Chloride. It is not just the fact that brine sticks well that makes it a good ice melter however. In many cases, brine is made with magnesium chloride. Magnesium chloride is a salt like the more familiar sodium chloride crystals, or rock salt, but it melts ice at lower temperatures. Unfortunately, if rock salt is bad for your car, then magnesium chloride is worse. Any salt is bad news for the iron and steel in your car when it mixes with water. That crust of salt your car develops in winter is just waiting to mix with water and eat away the steel. Fortunately, sodium chloride requires fairly high humidity levels to wick moisture from the air. In the cold dry air of winter, there isn't enough water in the air for the sodium chloride crystals to dissolve in. So they stay crystals and do relatively less harm to your vehicle. Magnesium chloride however mixes with water readily at low levels of humidity. Even in a dry time of year like winter, your vehicle's crust of magnesium chloride is busy sucking moisture out of the air and combining with it to form the water/salt combination that is so corrosive. And because it was spread as a brine to begin with, there is more of it, in more tight places on and under your car.
