Leaving a car unused for weeks or months calls for more than parking it and locking the doors. Dust, moisture, low battery charge, and old fluids can create problems while the vehicle sits. A few deliberate steps before storage can help protect its condition and make it easier to return to the road. Use this checklist to prepare the exterior, cabin, fluids, battery, and tires, then confirm the storage space is suitable for your vehicle.
Clean Inside and Out
Wash and dry the exterior before storing the car. Remove road salt, bird droppings, tree sap, and other residue that can damage paint if left in place. Clean the wheels and wheel wells, then apply wax or a paint sealant if appropriate for your finish. Make sure the car is completely dry before covering it; trapped moisture can encourage corrosion or leave marks.
Vacuum the cabin and remove food, wrappers, and anything that could attract pests or develop an odor. Wipe down surfaces, clean the windows, and check under the seats and in the trunk. Leave the interior dry. If you use a moisture absorber, choose one made for vehicle interiors and position it securely so it cannot spill or interfere with controls.
Check Fluids and Fuel
Check the oil, coolant, brake fluid, and washer fluid levels, and look for visible leaks. Follow the owner’s manual for fluid specifications and service intervals. If the oil is due for a change, take care of it before storage; used oil can contain contaminants. Do not open a hot cooling system, and have a mechanic address leaks or warning lights rather than treating storage as a substitute for repairs.
For a gasoline vehicle, consult the owner’s manual about fuel preparation. A fuel stabilizer may be appropriate for a longer storage period, but use the product as directed and add it before filling the tank if its instructions call for that. Keep fuel away from ignition sources, and follow the facility’s rules. Electric and plug-in hybrid vehicles need their own battery-storage guidance from the manufacturer.
Protect Battery and Tires
A parked car can lose battery charge, especially when security systems or other electronics remain active. If the storage location has a suitable outlet and permits it, use a battery maintainer designed for your battery type. Connect it according to the manufacturer’s instructions. Otherwise, ask your mechanic whether disconnecting the battery is suitable; this may reset vehicle settings or affect electronic systems.
Check tire pressure against the vehicle’s recommended cold-pressure setting before parking. Tires can lose air over time, so plan to check them when you return. For extended storage, ask the owner’s manual or a tire professional whether tire cradles or another method is recommended. Avoid leaving the car on a jack unless the vehicle and storage instructions specifically call for that setup.
Set Up the Storage Space
Choose a secure, dry space with enough room to enter and exit without scraping the vehicle. A breathable, well-fitted car cover can limit dust while allowing moisture to escape; avoid plastic sheeting that can trap condensation against the paint. Check that the parking area is clear of objects that could fall, leak, or block access, and follow the storage provider’s rules for covers, chargers, and fuel.
Before leaving, remove valuables and document the car’s condition with photos. Confirm the windows are fully closed, the doors are locked, and the parking brake is handled according to the owner’s manual and storage conditions; some vehicles may be better secured with wheel chocks for extended stays. Keep a record of the location and any maintenance completed. Arrange periodic checks if your storage plan allows them.
A clean vehicle, sound fluids, a considered battery plan, and properly prepared tires make a better starting point after storage. Check the owner’s manual for model-specific instructions, and resolve existing maintenance issues before parking.
