Six Steps To Protect Your Corvette In Storage

It’s that time of the year…time to start thinking about storing your beloved Corvette for the winter season. But it’s not as simple as pulling into the garage and locking the door! Performing just six extra tasks now will ensure you won’t have any nasty surprises waiting for you in the springtime.


Probably the best first step you can take is to properly and thoroughly clean your car. Start with the engine compartment; remove any dead leaves or other detritus you might have picked up on the road over a long summer. Move around to the wheels and scrub those tires, getting any mud or stones out of the treads and making those whitewalls shine. Use a portable vacuum to suck up any dirt or food particles—you wouldn’t want any unwelcome visitors like mice or bugs—then spend some time detailing the dash, console, and seats. Lastly, grab some towels and a chamois to give the exterior a good wash and polish.


As secure as your garage or storage unit might be, there’s always the risk of a rodent nibbling its way inside and then, inevitably, into your Corvette. Oh, the horror when you unveil your car months later to reveal chewed wires, torn fabric, mouse droppings or perhaps even a dessicated corpse. Close any vents beforehand and make sure all windows are tightly closed. A wad of industrial steel wool stuffed into the tailpipe will cut off one easy entrance but make sure to seal it off with some electrical tape.


Worried about insects? There are many organic, non-toxic repellents on the market which use lemongrass or mint as the base. These are great because they smell nice but bugs can’t stand them. A concoction of water, hot pepper flakes, and habaneros (used sparingly) will effectively repel rodents. A few squirts from a spray bottle with either repellent around the tires and baseboards will help. Some folks even use dryer sheets to ward off unwanted company!


Keeping your Corvette off the floor will also deter curious passengers who might sneak into the garage looking for a warm place to hide. So jack it up! The tactic of raising the car even a few inches has the additional benefit of allowing access to the floor underneath, so you can sweep up any dust that accumulates during the off-season. Got a hardtop? Lift it with a hoist to get it out of the way and protected from accidental damage.


Over the course of time during storage, your battery may lose its charge. You can remove it altogether, but that’s not always necessary. Technology has given us a better solution with automatic chargers and maintainers. Hook it up for a fully automatic trickle charge. These maintainers can also be used to bring dead batteries back to life.


There are other dangers than creepy crawlies. Light and just plain old air can fade your interior or degrade your custom paint job. Combat that with a tight-fitting car cover or even a full body car capsule. Covers have the added bonus of making dust cleanup a snap. Make sure to toss in a few STA-DRY Dry Packs to cut down on moisture.

It may be sad to say goodbye to your Corvette for the season, but it would be even more heartbreaking to find a host of ills to clean up or fix in the spring. Minimize that risk by rolling up your sleeves and giving your ride the attention it deserves now.

  1. I have a C2 that I have owned for 15 years now. I also highly recommend changing oil and tranny fluid and fogging the motor if you are not going to use the car for a prolonged period of time.

  2. Temperature and humidity fluctuations are a huge problem. The ideal temperature for preservation is around 64 degrees. The Philadelphia Museum of Art likes a range of 68-degrees to 72-degrees. That’s a four-degree variation over a month’s time. The same with humidity. In an ideal world your cars should be stored in an area that has between 45% and 55% humidity. What’s more important though is that the humidity be consistent. Wild fluctuations will cause more damage than any given level.

  3. Is it not a good thing to start your car at least once a month and bring it to operating temperature? I’m concerned about seals as well.

      1. Not really. The problem is starting the car creates condensation. You need to drive it at least 20 miles to eliminate all of the moisture. Everything has to come up to temperature.

      2. Yes, driving the car would be a huge bonus. For the people who can’t though, starting the car when possible is much better than just letting the car sit.

  4. Great article, as for the tires, over the last 16 years, I have placed 12 x 12 inch, 1/2″ thick plywood on the garage floor, followed by 4 layers of thick carpet remnants, for under the tires and have never experienced any flat spots, plus this is a very inexpensive step in preventing flat spots on your tires!

  6. Great article! What is the best way to prevent flat spotting the tires, or is that not a problem? My mechanic says that my tires are too far out of balance to balance, probably due to flat spots due to storage. The tires were on the car when I bought it, so I don’t know what the previous owner did in terms of a storage procedure. Thanks

    1. Some sort of thick padding has been known to do the trick. As Michael Mikolajczyk posted above, he used 12 x 12 inch, 1/2″ thick plywood on the garage floor, followed by 4 layers of thick carpet remnants, for under the tires and hasn’t experienced any flat spots from storage.
