Three Ways to Avoid Salt Damage to Your Car this Winter

If you live in an area that gets a lot of snow, then you’re probably used to seeing rock salt build-up on your vehicle each winter. It’s unfortunate but necessary – salt lowers the freezing temperature of water, which means that rather than turning to ice at 32 degrees, water may freeze at 20 degrees or lower. The result is that the snow and ice on the road melt even in freezing temperatures, making driving conditions safer. Unfortunately, a side effect of ice-melting rock salt is the corrosion it causes to car bodies and undercarriages. Read on to find out how salt damage works, and a few ways you can protect your vehicle from corrosion.

Three Ways to Avoid Salt Damage to Your Car this Winter

How salt corrosion works

There’s a complicated scientific explanation for the way salt speeds up the corrosion of metal, but the basic idea is simple. Water contains oxygen which oxidizes metal, causing it to rust. Salt speeds up oxidization, which is why metal near coasts, which comes in contact with salt and water in the air, is more susceptible to rust.

Three ways to avoid salt corrosion

1. Wash and wax your car regularly – During months when roads are heavily salted, it’s a good idea to wash your car every one to two weeks. And adding a layer of car wax every three or four car washes can provide extra protection against the salt. Doing so can prevent long-term salt corrosion, and save you money on body repairs down the road.

2. Repair paint flakes – The paint, clear coat, primer and other layers that cover your vehicle aren’t just there to make your car shine in the sunlight. The various coats protect the metal of your vehicle from oxidation and corrosion. Over time, these layers can peel, leaving the metal vulnerable to rust. Look for places where the paint or clear coat are peeling, and consider getting them repainted. Catching these patches can prevent rust before it starts.

3. Get rid of rust when you find it – Keeping an eye on your vehicle’s body paint is a good rust prevention method, but rust often begins on the undercarriage of the car. Since this surface is closest to the ground, it has more contact with salt and water. Have a mechanic inspect the undercarriage after each winter to look for signs of rust. If caught early, rust can be ground away, primed and repainted.

Salt isn’t the only risk your vehicle faces this winter. Road conditions can become slick in areas where salt hasn’t been applied, or if the weather drops below about 15 degrees and the salt is less effective. Car accidents resulting from dangerous road conditions cause a lot more damage than rust in the wheel well, but the cost of repairs can be minimized if you have automotive insurance. To find a policy that protects your vehicle, compare car insurance quotes online, and to protect it from rust and corrosion, remember to wash your car regularly this winter.

  1. That was a big problem in Michigan because we were on salt for months on end. I always made sure to wash it regularly and include the undercarriage too.

  2. I’m feeling really lucky that I live in So Cal right about now!

  3. Just got a carwash yesterday. So sick of the salt. Meh!

  4. I never knew paint chips needed to be dealt with immediately. I think our car has a few spots that need attention. Good thing to know. Yikes!

  5. First of all I love your redesign!
    I never thought about washing my car in the winter even though I’ve seen people do it.. I always thought it was too cold. LOL! Thanks for the information. I def don’t want to ruin the paint on my car.

    Thanks for sharing these tips. I hate what salt does to my car during the winter.

  7. i hate that salty stuff

  8. My husband had the same problem last winter and you really explained it in detail here. I never even know how salt can actually damage the vehicle until now. I just knew that it damaged our car last winter. Since we didn’t know back then how we can actually prevent salt from damaging the car, we spent a hefty amount for car repairs. I guess people are not the only ones who get to experience the disadvantages of too much snow during winter.

  9. Salts is a pain in the head so as the winter season. We just have to properly maintain our vehicle to avoid any incidents affecting it’s performance. Thanks for the great tips!
