How to Store a Car Long Term Without Causing Damage
Storing a car long term is not just about parking it and walking away. When a vehicle sits unused for weeks or months, small issues can quietly turn into expensive problems. Batteries drain, tires develop flat spots, fluids break down, and moisture finds its way into places it should not be.
Whether you are storing a classic car, a second vehicle, or a car you will not need during the winter months, preparation matters.
Start With a Full Cleaning
Before storage, wash the exterior and clean the interior thoroughly. Dirt, salt, and road grime can damage paint over time, especially if moisture is present. Inside the car, remove food, paper, and anything that could attract pests.
According to AAA, leftover food and organic material inside a vehicle is one of the most common reasons rodents damage stored cars.
Protect the Battery and Fluids
Car batteries slowly discharge when not in use. If possible, disconnect the battery or use a battery maintainer to keep it charged. Letting a battery sit fully drained can permanently shorten its lifespan.
Check oil, coolant, brake fluid, and windshield washer fluid before storage. Fresh oil helps prevent internal corrosion, especially for long storage periods.
The Car Care Council recommends changing oil before long-term storage to reduce engine wear caused by acidic contaminants.
Tire Care and Positioning
Tires can develop flat spots when a vehicle sits in the same position for months. Inflate tires to the manufacturer’s recommended pressure before storage. For very long storage periods, consider placing the vehicle on jack stands to remove weight from the tires.
If you are storing multiple seasonal items at the same time, strategies from seasonal storage swaps can help organize space efficiently without stacking items unsafely.
Choose the Right Storage Environment
Indoor storage protects your vehicle from temperature swings, moisture, and weather exposure. Climate-controlled storage is especially helpful for older vehicles, convertibles, or cars with leather interiors.

Cover and Secure the Vehicle
Use a breathable car cover designed for indoor storage. Avoid plastic covers that trap moisture. Make sure the parking brake is released to prevent brake pads from sticking, and use wheel chocks instead.

Check on the Car Periodically
Even in long-term storage, checking on your vehicle every few months helps catch issues early. Look for leaks, pest activity, or tire pressure changes.
Car storage is about preservation, not just parking. With the right preparation and the right environment, your vehicle can come out of storage ready to drive instead of needing repairs.
