Winter Storage Tips for Classic Cars

As winter approaches, owners of classic cars know that proper storage isn’t just about tucking a vehicle away until spring—it’s an essential part of preserving its beauty, performance, and value. Harsh winter elements and prolonged inactivity can take a toll on vintage vehicles if they’re not stored with care. 

At Altezza Restorations, we’re passionate about helping classic car owners in Connecticut keep their vehicles in pristine condition year-round. Here’s a step-by-step guide to prepping your classic car for winter storage so it’s ready to shine again come spring.

1. Choose the Right Storage Location

• Find a Climate-Controlled Space: Storing your classic car in a climate-controlled environment helps prevent temperature fluctuations that cause condensation, which can lead to rust. If possible, avoid unheated garages or sheds.
• Keep it Dry: If a climate-controlled space isn’t available, ensure the area is dry and well-ventilated. Placing a moisture-absorbing product nearby can also reduce humidity.
• Avoid Concrete Floors: Parking on a concrete floor can cause moisture build-up. Place a vapor barrier, such as a plastic sheet, under the car, or use a car storage mat.

2. Clean Your Car Thoroughly

• Wash and Wax: Before storing, thoroughly wash and wax your car. Dirt, grime, and salt can corrode paint, while a good wax layer adds protection.
• Clean the Interior: Vacuum seats, wipe down surfaces, and remove trash. Food particles can attract rodents, which might damage wiring and upholstery.
• Condition Leather and Vinyl: Use a quality conditioner on leather and vinyl surfaces to prevent cracking in dry winter air.

3. Address Fluids and Engine Protection

• Fill Up the Gas Tank: A full gas tank helps prevent moisture from forming inside the tank. Adding a fuel stabilizer will also keep the gas from degrading.
• Change the Oil and Filter: Used oil can contain contaminants that may corrode engine components over time. Changing the oil and filter before storage is a small but essential step.
• Flush and Fill Antifreeze: Verify that the coolant mix is appropriate for winter temperatures. This protects your engine from freezing and cracking.
• Remove or Maintain the Battery: Disconnecting the battery prevents it from draining over time, or consider investing in a trickle charger to keep it charged and in good condition.

4. Take Care of Tires and Suspension

• Inflate Tires Properly: Ensure the tires are inflated to the recommended PSI to avoid flat spots. Cold weather can cause tire pressure to drop, so keep them properly inflated throughout the storage period.
• Use Tire Jacks or Move the Car Periodically: If possible, use jack stands to lift the car off the ground, reducing the risk of flat spots. Alternatively, move the vehicle slightly every few weeks to shift the tires.
• Lubricate Moving Parts: Apply grease or lubricant to joints and moving parts, such as the suspension and hinges, to prevent stiffness or rust.

5. Seal Openings to Prevent Critters

• Close Windows and Sunroof: Fully close windows, the sunroof, and any other openings to keep small animals from getting inside.
• Cover the Exhaust and Intake: Use steel wool or other rodent-proof material to cover the exhaust pipe and air intake. This helps prevent animals from nesting in your car over the winter.
• Avoid Using Harsh Chemicals: If using mothballs or rodent deterrents, avoid placing them directly on or near sensitive parts, as they can cause damage over time.

6. Cover Your Car Correctly

• Invest in a Quality Car Cover: Opt for a breathable, weatherproof cover designed for classic cars. This will help prevent dust buildup while allowing air to circulate.
• Secure the Cover: Make sure the cover is snug to prevent it from moving or scratching the paint. Avoid plastic tarps, as they can trap moisture.

7. Schedule Routine Check-Ins

• Inspect Monthly: If possible, check on your vehicle every few weeks to make sure everything remains in order. Look for any signs of rust, leaks, or pests.
• Run the Engine Briefly: If feasible, start the car and let it run for a few minutes every month to keep the engine lubricated.
