How to DIY Winterize Your Car for Storage (Classic & Collector Cars)

How to DIY Winterize Your Car for Storage (Classic & Collector Cars)

Posted by Emily R. on 18th Sep 2025

If you’ve got a classic car, sports car, or just a “nice ride” you don’t want braving the snow, salt, and slush this winter, proper storage prep is key. Winterizing isn’t just about tossing a tarp over the car and calling it good—doing it right can prevent costly repairs and keep your vehicle road-ready when spring arrives.

Here’s a step-by-step guide (and some tools that will make your life a whole lot easier)

1. Clean Inside and Out

  • Why: Dirt, salt, and grime can eat away at paint and chrome. Even crumbs inside the cabin can attract pests.

  • What to Use:

Pro tip: A good wax coat adds a protective barrier against moisture during storage.

2. Top Off and Treat Fluids

  • Why: Old fuel can gum up lines, while unprotected cooling systems and oil can lead to corrosion.

  • What to Do:

    • Add a fuel stabilizer

    • Change the oil and filter.

    • Check antifreeze levels with a coolant tester to ensure proper freeze protection.

3. Protect the Battery

4. Mind the Tires

  • Why: Cold temps can cause flat spots if the car sits too long.

  • Options:

    • Inflate tires to recommended PSI.

    • For extra peace of mind, lift the car with a hydraulic floor jack and secure it on jack stands to take weight off the tires and suspension.

5. Keep Out Moisture and Critters

  • Why: Mice love warm garages and car interiors. Moisture can cause mold and rust.

  • Tools and Products:

    • Place desiccant packs or a car dehumidifier inside.

    • Use steel wool in the tailpipes to deter pests (remove before driving!).

6. Cover It Right

  • Why: Not all covers are created equal. A breathable cover protects paint and interior without trapping condensation.

  • What to Get: A car storage cover designed for your vehicle type—avoid cheap plastic tarps.
