Many drivers take their cars off the road to avoid harsh winter weather, but improper storage can lead to as much, if not more, damage than exposure to the winter elements. Taking a few critical considerations for automotive winter storage can make the springtime return to service virtually trouble free.
Pests are a major consideration in stored vehicles, and some pests can actually damage a vehicle's interior. Before storing the car for the winter, thoroughly detail all surfaces--including under the seats--to remove any residue, spills, dropped food or other scraps that may seem interesting to insects and animals seeking food and warmth during the winter. For some extra security, consider adding a couple of boxes of d-CON or other pest repellent while the car is in storage.
Even if the car is to be stored in a garage, a quality car cover likely will prevent erosion from dust, wind, sand, the sun and other natural elements. Be certain to securely attach the car cover at all latch points, as a car cover flapping in the wind can quickly scratch and damage expensive paint jobs. If the car cover is not waterproof, be sure the car is located somewhere with enough sunlight to dry any moisture that may accumulate.
While this step may seem like a minor consideration, car computers can become erratic and even damaged when faced with a diminished source of power. Since car electronics continue to draw a small amount of electricity even when not in use, a stored car can drain even a fresh battery in a matter of weeks. Before disconnecting the battery for storage, though, be certain to write down any radio or security codes that may be required to restore full operation in the springtime.
If possible, and if allowed by local ordinances, consider jacking the car up and using either jack stands or concrete blocks to keep the tires off the ground. If the car is in storage more than a month and is not driven, tires may develop flat spots that create a rough ride when the car is returned to service. It may also be a good idea to reinspect tires before attempting to drive on them after storage, as dry rot can become a serious problem.
