Washing your car is probably the best thing you can do to prevent rust.

Washing every two weeks is a good practice to follow, with additional washes if a car becomes exceptionally dirty.

As you wash your car every two weeks, don’t forget the undercarriage, especially if you live in an area where it snows. During the winter, salt and other chemical deposits used on roads to melt snow and ice can coat a vehicle’s undercarriage with corrosive residue that can cause rust. Most automatic car washes offer undercarriage washes; if you wash your vehicle at home, find a safe way to jack the car up and spray it off with a hose.

It’s important to know how to fix rust spots on a car so they don’t spread. It requires scraping any rust you find off using fine grit sandpaper or a razor. You can then apply a rust arrestor. Once the arrestor dries, you can apply primer and color match your car’s paint to touch the area up.

Rust commonly occurs where two pieces of metal meet, especially when there is room for them to rub together. The rubbing can wear down protective layers on the car, making it susceptible to rust. Some of the key ways to check these areas include opening the hood, doors, and trunk as you inspect your vehicle, keeping an eye out for signs of bubbled-up paint.
