1. Clean the Vehicle Thoroughly

  • Wash and Wax: Clean the exterior to remove dirt, road salt, and contaminants that can cause rust. Waxing adds an extra protective layer.
  • Clean the Interior: Vacuum and clean all surfaces to remove food particles and prevent odors. Make sure to clear out trash and personal items.
  • Condition Leather and Plastic: Use leather and plastic protectants on seats, dashboards, and door panels to prevent cracking in cooler temperatures.

2. Fill the Fuel Tank and Add Fuel Stabilizer

  • Full Tank: Filling the gas tank prevents condensation from forming inside the tank during temperature fluctuations.
  • Add Fuel Stabilizer: Use a fuel stabilizer to prevent the gas from degrading and clogging the fuel system. Run the engine for a few minutes after adding it to distribute the stabilizer through the system.

3. Change the Oil and Check Other Fluids

  • Change the Oil: Old oil can contain contaminants that can damage engine components during long-term storage.
  • Top Off Fluids: Check and fill the coolant, brake, transmission, and windshield washer fluids. Ensure there’s enough antifreeze in the coolant to prevent freezing if temperatures drop.

4. Disconnect or Maintain the Battery

  • Disconnect the Battery: Disconnecting the negative terminal prevents battery drain. Store the battery in a cool, dry place if possible.
  • Use a Trickle Charger: If you plan to leave the battery in the vehicle, use a trickle charger to keep it charged and avoid starting issues when you return.

5. Protect the Tires

  • Inflate Tires to Recommended Pressure: Tires can lose air over time, so inflate them to the recommended pressure.
  • Avoid Flat Spots: For long-term storage, consider putting the car on jack stands to relieve pressure on the tires. Alternatively, move the car a few inches periodically to prevent flat spots if jack stands aren’t an option.

6. Prevent Moisture and Pest Damage

  • Use a Car Cover: Use a breathable car cover to protect the paint and keep dust off the vehicle. Avoid plastic covers as they trap moisture.
  • Close Windows, but Leave a Small Crack: Roll up windows, but leave a tiny crack for airflow to reduce moisture buildup inside the car.
  • Plug Exhaust and Air Intakes: Use steel wool or foam to plug the exhaust pipe and air intakes to prevent rodents from nesting in the vehicle.

7. Ensure Proper Storage Conditions

  • Choose a Dry, Cool Location: Ideally, store the vehicle in a garage or storage facility that is well-ventilated and protected from the elements.
  • Use Moisture Absorbers: Place moisture absorbers (like silica gel packs or DampRid) inside the cabin to reduce humidity and prevent mold or mildew.

8. Avoid Engaging the Parking Brake

  • Use Wheel Chocks Instead: Engaging the parking brake over long periods can cause the brake pads to stick to the rotors. Use wheel chocks to prevent movement.

9. Additional Security Measures

  • Cover the Vehicle Identification Number (VIN): Place a cloth or paper over the VIN if the car is visible to deter theft.
  • Lock the Vehicle: Ensure all doors and the trunk are locked for added security, even in a storage facility.
