Avoid prime salt times
If you have to get on the highway in bad weather, don’t do it right after and before a storm, because you are more liable to run into fresh road salt at those times.
Guard against the fresh snow
For both car care and security reasons, don’t drive in deep snow. To begin, you can get stranded and stuck. And deep snow can put salt in the undercarriage, where it’s hard to remove. This usually leads to corrosion and even drivability issues.
Wash while it’s warmer
In washing the salt off in the winter, do so in the daytime so your car has time to dry. You won’t like the wet stuff to freeze on your finish after the temps fall. The outside temperature has to be 40°F or higher. To ensure a clean vehicle all season long, do again every eight days. To not have the locks freeze, open and close the doors after the work is done.
Let’s be real, winter can be tiring. Between snowstorms, having to wear all those layers, and frowning your face like an MMA fighter each time the wind picks up, most of us want to be outside as little as possible.
You rather not have to deal with a garden hose that sprays icy water and red-raw knuckles. Though, one peek at the wavy white lines of salt on car bodies, wheel wells, and even floor mats is enough to realize the obvious: you have salt in your car.
Find an Undercarriage Cleaner
The car area that is most vulnerable to the rust and corrosion of winter is the one part you can’t clean by yourself: the underside. You really need to wash your car every week during the winter to get the salt off.
