How To Keep Your Car From Rusting This Winter?

Winter is just around the corner, and it’s that time of the year when your old and even new car sits covered in the snow when not in use. As bad as Wisconsin winters are for the car’s engine with all the cold starting issues and stuff, they are equally bad for your car’s exterior paint, especially if you notice rust. Read on to this blog post from Frank Boucher Volkswagen of Janesville and find out how you can avoid your car from rusting this winter.

The first thing you should be doing before acting is identifying if your car has any rusting at all. Check the exterior paint for chipping and bubbles both on the outside and under the vehicle. Paint chipping off and bubbling can be signs of underlying rust which can aggravate during winter and spread to other parts. The most susceptible areas where you can spot rust are wheel wells, roofs, and your car’s undercarriage.


How Can You Drive Safely in Foggy Conditions


Wash and wax your car

Wash your car either yourself or at a car wash. Regular washing and cleaning will remove all the dirt, mud, and salt which could eat into the car’s paint and metal from the wheel wells and other parts. Apply wax to the car and make it shiny because a clean surface helps you spot hidden rust spots that would otherwise be covered with dirt.

Transport authorities pre-salt some roads in anticipation of snow (as a melting agent), causing sodium chloride to stick to the car wheels, wheel wells, and undercarriage. Salt is the best friend of rust, so wash your car at least twice every month. You can add baking soda to the soap and water to neutralize road salt.

Keep your car interiors clean and dry

Sometimes liquids spill inside our cars, seeping into the corners and remain there for a long time. This may trigger rusting. So, make sure your car’s interiors are fresh and blown dry using an air blower. Ensure that the car doesn’t smell moldy, as that could be because of moisture inside torn car seats.

Arrest the rust and spray

Once you’ve identified the rust spots and cleaned your vehicle thoroughly, you might want to arrest the rust from spreading. You can scrape off the rust with a razor blade or fine-grit sandpaper. Once this is done, apply an over-the-counter rust arrestor which should be available at most auto parts stores. Let it dry, and then apply a thin coat of automotive primer over the dried rust arrestor.

Finally, identify the exterior paint color option and spray it over the primer and let it dry. Avoid spraying on brake rotors, drums, linings, calipers, and parts that heat, such as catalytic converters.
