Storing a car in a storage unit can be a practical solution for various reasons, from seasonal storage to freeing up garage space. However, a standard storage unit isn’t the ideal environment for a vehicle and requires careful preparation to prevent potential issues. This guide, drawing from expert advice in car communities, outlines essential steps to protect your car when using storage units.
Preparing Your Car for Storage
Proper preparation is crucial before placing your car in a storage unit. These steps will help mitigate risks associated with non-climate-controlled environments and ensure your vehicle remains in good condition.
Fuel Considerations
Fuel stability is paramount, especially for long-term storage. Always use a fuel stabilizer to prevent fuel degradation and potential damage to your car’s fuel system. For gasoline, it’s generally recommended to fill the fuel tank completely. A full tank minimizes the air space, reducing condensation and the risk of rust inside the tank. Experts also suggest using non-ethanol fuel if possible, particularly for extended storage periods, as ethanol can attract moisture and lead to fuel separation.
Battery Care
A car battery will naturally discharge over time, especially when not in use. To prevent a dead battery, disconnect the negative battery terminal. This simple step prevents parasitic drain and extends battery life during storage. For optimal battery health, consider using a battery tender or maintainer, if your storage unit has a power outlet. However, in a typical unit without power, disconnection is the most practical solution.
Tire Protection
Tires can develop flat spots if a vehicle sits in one position for an extended period. To prevent this, inflate tires to the maximum recommended pressure listed on the tire sidewall. Alternatively, you can use tire cradles or supports to distribute the car’s weight more evenly and minimize flat spotting. If you are storing the car for a very long period, placing the car on jack stands to take the weight off the tires entirely is an even better solution, but may be impractical in a storage unit setting.
Fluid Management
While not always necessary for short-term seasonal storage, some experts recommend changing the engine oil before storage. Old engine oil can contain contaminants that could corrode engine components over time. This is particularly important if you are storing the car for several months or longer.
Brake System
To prevent brake pads from sticking to the rotors, especially in humid environments, release the parking brake. Instead, use wheel chocks to secure the vehicle and prevent it from rolling. This avoids potential corrosion and ensures your brakes function correctly when you take the car out of storage.
Protecting Your Car Inside the Storage Unit
Once your car is inside the storage unit, further steps can be taken to protect it from the environment and potential pests.
Moisture Control
Storage units, especially non-climate-controlled ones, can experience temperature fluctuations and humidity. Avoid using plastic car covers as they can trap moisture against the car’s surface, potentially leading to rust or paint issues. If you want to use a cover, opt for a breathable dust cover to protect against dirt and debris while allowing air circulation. Consider using moisture absorbers or desiccants inside the car and storage unit to further combat humidity, especially if you live in a damp climate.
Rodent Deterrence
Rodents can cause significant damage to cars in storage, chewing on wiring and nesting in interiors. Implement a rodent control plan by placing traps and deterrents around the storage unit and inside the car. Some car owners recommend using dryer sheets or mothballs as rodent repellents, although their effectiveness can vary. Regularly check for signs of rodent activity and replenish deterrents as needed.
Dust and Debris Protection
While avoiding plastic covers is advisable, a light, breathable dust cover can be beneficial in keeping dust and debris off your car. This is especially useful in storage units that might not be perfectly sealed. Ensure the cover is indeed breathable to prevent moisture buildup. Regularly check the car and the unit for any accumulating dust or debris.
By following these guidelines, you can effectively protect your car while it’s stored in a storage unit. Careful preparation and proactive measures will help ensure your vehicle remains in excellent condition, ready for the road whenever you need it again.
