Vehicle Storage: How to Avoid Rust and Corrosion

When it comes to vehicle storage, rust and corrosion are two of the biggest concerns. Whether you’re storing a car, truck, or any type of vehicle for an extended period, protecting it from the elements is key. Rust and corrosion can damage the exterior, weaken the structure, and lower the vehicle’s overall value.

Fortunately, there are several ways you can minimize the chances of rust or corrosion while your vehicle is in storage. In this article, we will explore these methods and provide helpful tips on how to keep your vehicle in good condition.

Choose the Right Vehicle Storage Facility

The first step in preventing rust and corrosion is selecting the right vehicle storage option. Keeping your vehicle in a well-maintained storage facility can greatly reduce exposure to moisture, which is the leading cause of rust. Here are some factors to consider:

Indoor vs. Outdoor Vehicle Storage

Indoor vehicle storage is ideal for protecting your car from the elements. It shields the vehicle from rain, snow, and even humidity. By keeping your vehicle indoors, you reduce the chances of moisture building up on metal surfaces, which often leads to rust.

If you opt for outdoor vehicle storage, try to cover your vehicle with a breathable car cover. While this won’t provide the same protection as an indoor facility, it will still help reduce moisture buildup.

Climate-Controlled Vehicle Storage

If possible, look for climate-controlled vehicle storage units. These units keep the temperature and humidity levels stable, which is crucial in preventing corrosion. Temperature fluctuations can cause condensation, and condensation leads to rust. By choosing a climate-controlled space, you reduce the risk of moisture accumulating on your vehicle’s surface.

Prepare for Vehicle Storage

Before placing your car in vehicle storage, it’s important to take certain steps to protect it from rust and corrosion. Proper preparation can go a long way in minimizing the risks.

Clean and Wax the Exterior

Before storing your vehicle, give it a thorough wash and wax. Cleaning off dirt, salt, and grime helps prevent corrosion from starting. Any residue left on the surface of your vehicle can trap moisture, which may accelerate rust formation.

Waxing your car adds an extra layer of protection. The wax acts as a barrier between the metal and moisture, reducing the likelihood of rust. This is especially helpful if you’re using outdoor vehicle storage or if the storage facility isn’t climate-controlled.

Apply Rust Protection Spray

For additional peace of mind, consider applying a rust prevention spray to your vehicle’s undercarriage. Many areas prone to rust, like the wheel wells and exhaust, can benefit from this extra layer of protection. Rust protection sprays can help reduce the chances of moisture getting into areas that are harder to inspect regularly.

Make sure to apply the spray evenly and let it dry fully before moving the vehicle into vehicle storage. This step adds another level of defense against rust.

Control Moisture Levels in Vehicle Storage

Since moisture is the main contributor to rust and corrosion, controlling it is key when your vehicle is in storage. Luckily, there are several strategies to help you reduce moisture inside and around your car.

Use Desiccants Inside the Vehicle

One simple way to control moisture inside your car is by using desiccants. Desiccants are moisture-absorbing materials that help keep the interior of your vehicle dry while in vehicle storage. You can place silica gel packs or other desiccants in various areas, such as under the seats, in the trunk, or inside the glove compartment.

By doing this, you reduce the chances of moisture accumulating inside the vehicle, which could lead to corrosion on metal components and rust in areas you might not check frequently.

Ensure Proper Ventilation

If you’re storing your vehicle in an enclosed space, make sure there is adequate ventilation. Stale air in vehicle storage can increase the risk of condensation, especially in areas with high humidity. Ventilation helps reduce moisture buildup, providing an extra layer of protection against rust and corrosion.

Leaving the windows slightly cracked or installing a vented car cover for outdoor storage can help improve airflow inside your vehicle.

Check and Maintain Vehicle Fluids

Another essential step in preventing rust and corrosion during vehicle storage is ensuring that your vehicle’s fluids are at the right levels. Certain fluids, when left unchecked, can lead to internal rust or corrosion in the engine and other parts.

Top Off Fluids

Before putting your vehicle in vehicle storage, make sure to top off all fluids, including the engine oil, coolant, and brake fluid. Fresh fluids help prevent rust inside the engine and cooling system, as well as reduce the risk of corrosion in the brake lines.

If you’re planning to store the vehicle for several months, consider changing the oil before storage. Old oil can contain contaminants that may contribute to rust inside the engine.

Use a Fuel Stabilizer

If you’re storing your vehicle for more than a month, it’s a good idea to use a fuel stabilizer. Over time, gasoline can break down and form varnish-like deposits, which may lead to corrosion in the fuel tank and fuel lines. A fuel stabilizer can help keep the gasoline fresh and protect your vehicle from internal corrosion during long-term storage.

Regular Inspections During Vehicle Storage

Even while your vehicle is in vehicle storage, it’s a good idea to check on it periodically. This allows you to spot any early signs of rust or corrosion and take action before the damage becomes severe.

Look for Signs of Rust

Every few weeks, inspect your vehicle for any signs of rust. Pay special attention to areas where moisture tends to accumulate, such as the undercarriage, wheel wells, and door frames. If you spot any rust forming, address it immediately to prevent it from spreading.

You can gently sand off surface rust and apply a rust converter to treat the affected area. Taking these small steps can help extend the life of your vehicle and prevent further damage.

Run the Engine

If possible, try to run the engine for a few minutes during storage. This helps circulate fluids and keeps parts lubricated, reducing the risk of corrosion. Additionally, starting the vehicle can help remove any moisture that may have built up in the engine or exhaust system.

Conclusion

Rust and corrosion are common concerns when placing a car in vehicle storage, but with proper preparation, you can minimize the risks. Choosing the right storage facility, controlling moisture, and regularly checking your vehicle are all important steps to ensure it remains in good condition.

Although it’s impossible to completely eliminate the risk of rust, taking these precautions can help protect your vehicle and maintain its value over time.
