Road salt, typically made from sodium chloride, is spread on roads to prevent the formation of ice and snow accumulation, which can cause hazardous driving conditions. At Phoenix Collision, we understand how road salt can gradually damage your car, and we’ll explain why regular washing is crucial for keeping your vehicle in top shape during the winter months.
What is Road Salt and Why Is It Used?
Road salt, typically made from sodium chloride, is spread on roads to prevent the formation of ice and snow accumulation, which can cause hazardous driving conditions. While it’s effective for improving traction and reducing accidents, it can have a significant negative impact on your car’s exterior and undercarriage.
How Road Salt Damages Your Car
Road salt is highly corrosive. When it mixes with moisture from snow or rain, it forms a briny solution that can quickly find its way into every nook and cranny of your vehicle. Here’s how road salt causes damage:
Rust
The most significant risk posed by road salt is the development of rust. Salt speeds up the process of oxidation on metal surfaces, particularly when moisture from snow or rain is present. The undercarriage, wheel wells, and areas around the exhaust system are especially vulnerable.
Damage to Paint and Finish
The harsh chemicals in road salt can also erode the paint on your car, causing the finish to deteriorate. Over time, the paint can chip away, exposing the metal underneath to the elements. This makes your vehicle even more susceptible to rust and further damage. If not cleaned regularly, the salt can leave stains on the surface of your car, damaging its aesthetic appeal.
Brake and Suspension Wear
The undercarriage of your car, including the brake system and suspension components, is at risk due to salt exposure. Salt can settle on the brake lines, causing them to weaken or corrode, and can also impact suspension parts like struts and shock absorbers. If left untreated, this corrosion can cause mechanical issues and costly repairs.
Engine Components
While less common, road salt can even make its way into your engine components, especially through areas such as the grille and other vents. Once inside, it can cause the engine parts to degrade over time. This type of damage is more difficult to detect but can lead to costly mechanical failures if not addressed early.
How to Minimize Road Salt Damage
Washing your car regularly can help reduce the damage of road salt. It’s recommended to wash your car at least once every two weeks during the winter, especially after heavy snowfall. Washing your car during the winter months requires a bit more attention to detail. Here are a few tips to ensure you're doing it right:
Focus on the Undercarriage: Make sure to use a high-pressure rinse to clean the undercarriage and wheel wells, as these areas are particularly prone to salt buildup.
Choose the Right Soap: Look for a car wash solution that’s specifically designed for winter conditions and safe for your vehicle’s finish.
Don’t Forget the Wheels: Wheels are especially vulnerable to salt accumulation. Be sure to clean your wheels thoroughly, especially around the rims, where salt can gather.
Wax for Protection: After washing, consider applying a coat of wax to create a protective barrier between the salt and your car’s paint. This will help prevent the salt from sticking to the surface.
