Is salt corrosive? Will it damage my vehicle?
All chloride products used for anti-icing can be corrosive. Fortunately, western Washington experiences relatively mild and brief winter storm activity, reducing the amount of salt needed over the course of the winter. Most winter storms are also followed by rain. Our wet Pacific Northwest weather quickly washes salt off the roads thus significantly minimizing vehicle corrosion concerns.

It is worth noting that vehicle manufacturing techniques have evolved in recent years. Many of the newer vehicles have components made of plastic, fiberglass, stainless steel and other materials that are less prone to corrosion than steel. In any case, it is advisable to wash your car periodically throughout the winter months to remove any chemical residue.
