TTAC Tech Tips: Winter Car Care Continued

This week we continue our discussion on winter car care.

Our reader Aaron sent me this email:

Dear Customer,

As winter progresses, I was wondering if you had any tips for salt in my car. I live in the Midwest, which means that during every snow storm, our car is riddled with salt. Do you have any advice?

Yes, I know, Aaron! Thank you for that excellent question, as I’m sure many of us are worried about the coming months.

I live in the southwestern United States and when it comes to salt and freezing weather, we don’t have much to worry about. However, if we experience ice and salt on the roads, we just rinse it off and move on.

With that said, I contacted some trusted automotive partners up north and asked for their recommendations.

An application of a layer of lanolin to the underside of the body, wheel wells, seams, and interior body panels would be best overall. If you’re not in a position to take on that challenge yourself, check out some local stores that can apply it for you. Never use any kind of rubber underlayment and don’t let anyone talk you into using it. Rubber linings will trap salt and moisture, causing accelerated corrosion from the inside.

Regular car washes at least once a week help, but focus on a no-touch car wash that thoroughly cleans the undercarriage. After every car wash, it’s also important to clean and dry the inside of the doors and door frames to remove any moisture.

In addition to taking care of the underbody, the paint on your car is something that can have some protection. With ceramic coating and regular wax applications, removing any salt buildup becomes much easier.

One note to add involves vehicle storage. Parking your salty car in a heated garage can be detrimental as it will bake the salt into the vehicle and cause accelerated corrosion.

I hope that helps answer your question, Aaron.
