Lasting Impacts of Treating our Roads

When winter weather strikes Texoma, the Texas Department of Transportation (TXDOT) does everything it can to keep our roads safe by spreading de-icing agents all over them. For the last winter storm, they put down salt and Meltdown 20. Both are capable of corroding metal because they contain chloride. Newchannel 6 wanted to find out if they could damage your car.

"Not in this area, if we were somewhere other than here, where it's winter 4 months of the year, and it's an extended period of contact then yes," said Nissan of Wichita Falls Shop Foreman James Woods.

Woods said it would take years for the corrosive damage to become evident and cause problems.

If you are still worried about it damaging your car, you still might want to wait to wash your car. There is still salt and Meltdown 20 on the roads.

Woods said, "it just takes time. [The city] is not going to sweep it off." We'll have to wait until the next rain event to wash it completely off the roads.

If you want to be safe than sorry, you should focus on some specific parts of your car and not necessarily on the entire thing. Woods said you should wash the undercarriage.

If you have an older car that has been through quite a few snow storms, and think some of the metal is corroding. There are a few things you can look for.

"You'll start to see some white areas on the aluminum and stuff underneath...possibly some bubbling in the paint from the rust," said Woods.

If you still want an expert's opinion. Woods suggest to ask he mechanic the next time you get your oil changed. He said it's easy to spot if you know what you're looking for.

TXDOT uses both salt and Meltdown 20 because they work the best in different weather conditions. Meltdown 20 is less corrosive, but it cost a lot more.
