How Can I Protect My Car from Rock Salt?

March 27, 2020
Rock Salt Hitting Car

Many of us drive in the snow and ice every winter. To help keep roads safer, road crews will usually spread things like rock salt on the road to help provide drivers with better traction. Although rock salt is great for making the roads safer during the winter months, it can also cause damage to your vehicle.

Rock salt, also known as road salt, contains sodium chloride that works to lower the freezing point of water. Water normally freezes at 3 degrees Fahrenheit, but when ice and snow are exposed to rock salt, they need colder temperatures to stay frozen, making it difficult for ice to form.

Areas of the Car That Are Affected Most by Rock Salt

Road salt keeps the roads safer, but it can wreak havoc on your vehicle. When rock salt comes into contact with metal, it can cause a chemical reaction with any exposed metal, resulting in corrosion. If this corrosion continues, it can lead to rust forming, which can lower the resale value of your vehicle. The areas of your car most affected by rock salt include:

  • Muffler and exhaust system
  • Coil springs
  • Body panels
  • Subframe

The undercarriage of your car experiences most of the rock salt damage. It is important to keep in mind that once the corrosion caused by rock salt begins to eat away at your brake lines or axle, you are at a higher risk of an accident, making it vital for you to check underneath your car for any corrosion during the winter season.

Tips for Preventing Salt Damage

While rock salt can lead to extensive damage, there are a few ways you can prevent this damage. At Freedom Collision Center, we’ve put together some tips to help you keep your car corrosion-free, including:
  • Prepare your car in early fall with a thorough wash and wax. You may also consider adding a sealant over the new wax or even try out a ceramic coating for longer-lasting protection.
  • Have your car inspected and have any rusted components replaced before winter. You will also want to repair any deep scratches, chips, or rust spots.
  • Be sure to wash your car regularly throughout the winter, at least every few weeks. Use a car wash that also washes the undercarriage to ensure the salt residue is rinsed off.
  • In the spring, take the time to detail your car inside and out. Rock salt can also damage the interior of the care, including the floor mats, exposed metal, and carpeting.
