LITTLE ROCK, Ark. (KTHV) -- When heading onto the roadways, you may notice the salt and sand mixture left behind by crews working to make the highways safe.

But does that salt-sand mixture cause damage to your vehicles?

The Arkansas Highway and Transportation Department, along with AAA helped THV11 answer this question. Turns out, it's quite costly.

AAA says nationwide, drivers pay roughly $3 billion per year in rust-repairs caused by de-icing methods.

Salt and brine mixtures can wreak havoc on brake lines, fuel tanks and exhaust systems. It can also cause body damage to your car.

AAA says in the last five years, 22 million drivers experienced rust damage.

In Arkansas, the transportation department sprays super concentrated salt water on roadways, along with salt rock treated with beet juice.

Spokesman Danny Straessle says you don't really have to worry too much about it here.

"Not really because the amount of salt that we use is intense per event but we don't really have enough events to repeatedly get that material on your car. so, what we recommend, is if you did get out today and picked up some salt residue, a simple run through the car wash will take care of it,” said Straessle.

So we can verify because we live in a warmer climate and don't have much exposure to salt mixtures, damage to vehicles is minimal, if there's any at all.

Straessle says there is no need for any pre-treatment or solvent to protect your vehicle either. Just a good cleaning at the car wash in the next few days.

He did give a piece of advice: don't park in your garage until after you wash the dirt and salt off your car. Otherwise you may have another mess to clean up!
