Preparing Your Car for Long-Term Storage: A Checklist
Updated Jul 2026 · 3 min read
Parking a vehicle for a season or longer isn't as simple as locking the doors and walking away. A little preparation keeps your car healthy while it sits and makes for an easy, worry-free start when you return. Here's a practical checklist to run through before you drop your car at a storage facility.
Clean it thoroughly, inside and out
Start with a full wash and dry. Dirt, road salt, and grime left on the paint can cause problems over a long storage period, and any moisture invites corrosion. Clean and vacuum the interior too — food crumbs and debris can attract pests. Let everything dry completely before the car goes into storage.
Top off fluids and change the oil
Fresh oil protects the engine better than old, contaminated oil over a long rest. Top off other fluids as well, and make sure the coolant is appropriate for the storage climate. Full fluid levels help prevent internal condensation.
Fill and stabilize the fuel
A nearly full tank leaves less room for condensation to form inside it. Adding a fuel stabilizer helps keep the fuel fresh and protects the fuel system during a long sit.
Protect the battery
A battery slowly drains when a car sits unused. Connect a battery tender or trickle charger if power is available at your storage space. If not, ask the facility about options, or plan to disconnect the battery to reduce drain.
Set the tires
Inflate the tires to the recommended pressure before storage — tires lose air over time, and underinflated tires are more prone to flat spots. For very long storage, some owners raise the vehicle to take weight off the tires entirely.
Think about the parking brake
Leaving the parking brake engaged for a long period can cause the brake to stick. On a dry, level surface, many owners leave it off and use wheel chocks instead. Follow your vehicle's guidance.
Guard against moisture and pests
Moisture and critters are the two biggest enemies of a stored car. Consider moisture absorbers inside the vehicle, and block openings where pests might enter. A breathable car cover keeps dust off while letting the vehicle breathe — avoid non-breathable covers that trap moisture.
Choose the right storage environment
For a long-term rest, an enclosed or climate-controlled space offers the most protection, especially in harsh or humid climates. Match the environment to your vehicle's value and how long it will sit.
Document and confirm
Note the car's condition before storage, and confirm the facility's access rules, insurance requirements, and whether you can periodically start the car or check on it.
When you return
Before driving off, check the tire pressure, look for any signs of leaks or pests, reconnect the battery if needed, and let the engine warm up. A careful send-off and a careful return keep your vehicle ready for the road.
