Here's how road salt can damage your car

As soon as the weather dips below freezing, local authorities place salt and grit onto the road. These prevent ice from forming, and improve grip – and therefore safety – but they can be doing hidden damage to the underside of your car.

Salt prevents ice from forming by lowering the freezing point of water. It prevents falling rain or snow from freezing into ice, and is widely used across the globe throughout the winter months.
