A local mechanic warns drivers to wash their vehicles very quickly this week to prevent road salt from causing structural damage.
Stacy Burton said road salt can rapidly deteriorate a car’s undercarriage if left in place. He noted that while local vehicles usually fare better than those from the north, the corrosive material still poses a significant threat to frames and essential components.
“It can destroy one,” Burton said. “Frame, brake lines, everything is rusted out and destroyed.”
While drive-through car washes often feature undercarriage sprays, he noted they are not always efficient enough to remove all debris.
“Wash it as quick as possible,” Burton said. “If you can pressure wash it yourself, of course it’s better off.”
The primary concern regarding rust involves safety, as corrosion can compromise critical contact points like control arms, shocks, and struts. Additionally, damage to these components can negatively impact a vehicle’s resale value.
“Especially brake lines, most brake lines are metal,” Burton said. “So if they rust they will fail and if they fail your brakes will stop, but not very well.”
Burton observed that vehicles from northern states or areas like Fentress County and Kentucky often exhibit more serious damage due to frequent salting. However, local cars generally avoid severe issues because the region experiences less frequent salt exposure and regular rain helps rinse the roads.
“Just try your best not to drive on it if you can,” Burton said. “And if you do try to clean it off.”
Drivers are encouraged to utilize pressure washers or drive-in car washes as soon as road conditions allow.
