When you need to leave your car for an extended period—whether for a long vacation, deployment, or seasonal storage—it's essential to take the proper steps to protect it. Many car owners in Santa Ana, CA, trust places like STORAGExperts for long-term vehicle storage. With options such as Uncovered Parking 10x25, you can safely store sedans, SUVs, or even trucks. However, parking it and walking away can lead to serious issues later. A thorough inspection, attention to the brakes, checking antifreeze levels, and remembering key car storage tips are all important things to remember. In this case, giving your vehicle the proper care can extend its life and preserve your rights to hassle-free use once you're ready to reclaim your space. 

This is to ensure your vehicle stays in top condition. At the same time, in a storage facility, you must be mindful of several things—from fluids and battery care to protecting the interior, paint, and engine. This detailed guide will walk you through all the steps, precautions, and tips to help you avoid common problems and maximize your car storage investment. Each car storage tip we share increases your chance of keeping your vehicle in excellent condition. We've compiled insights from expert articles focusing on the values of preparation, the types of storage available, and the details that often get overlooked but make a big difference. 

Choose the Right Storage Facility in Santa Ana

First, find the right car storage facility in Santa Ana, CA. Not every place is created equal. While Uncovered Parking 10x25 is ideal for larger vehicles like SUVs or trucks, you should also consider indoor storage options for more valuable or delicate cars, like classic sedans or sports cars. A secure, well-maintained storage facility will offer proper protection, ventilation, and even climate control if needed.

You'll want to look for a facility that offers flexible rates and prioritizes security—with locks, cameras, and gated access. This protects your car from theft, vandalism, and extreme temperature changes. Santa Ana's climate is generally mild, but humidity, sun exposure, and moisture can still cause long-term damage.

Clean the Vehicle Inside and Out

Before storing your car, give it a complete cleaning. Wash the exterior thoroughly, apply a good coat of wax, and rinse away any dirt, road grime, or salt that may have built up. Waxing adds a protective coat to the paint, shielding it from dust, moisture, and sun exposure.

Clean the interior as well. Vacuum up all crumbs, wipe down surfaces—especially leather, plastic, and vinyl—and clear the air vents. Food remnants and leftover trash can attract rodents and pests, which could chew on wires, insulation, or other critical parts under the hood. Use fabric-safe cleaners for seats, and leave a box of baking soda inside to neutralize any lingering smell.

Check and Top Off All Fluids

Long-term storage means your car will be sitting idle for weeks or months. Start with an oil change, even if you're not due yet. Old oil contains contaminants that can damage your engine if left to sit. Top off other essential fluids, including brake fluid, coolant, transmission fluid, and windshield washer solution.

Also, check for leaks. Look under the vehicle for any signs of oil, coolant, or brake fluid escaping. Minor problems today can become big, costly issues later. Keeping everything topped up reduces the risk of internal corrosion and mechanical failure.

Add a Fuel Stabilizer to the Gas Tank

One of the most overlooked car storage tips is treating your gas tank. Gasoline begins to degrade in just 30 days. As it breaks down, it forms gum, varnish, and deposits that can clog your fuel tank and injectors.

Fill the tank completely and add a quality fuel stabilizer to prevent this. Drive the car for 5–10 minutes after adding it so the stabilizer circulates through the entire fuel system. A full gas tank also prevents internal rust from forming due to moisture in the tank.

Maintain the Battery Properly

Another common problem with long-term vehicle storage is a dead battery. If left unattended, even new batteries can lose charge due to small drains from electronics or clocks. You have two main options.

First, you can disconnect the battery entirely. Remove the negative terminal to prevent slow discharging. Alternatively, if your storage facility has electrical access, use a trickle charger to keep the battery topped off. This is especially useful for modern cars like Honda, Toyota, or Subaru, which often have sensitive electronics.

Avoid Flat Spots on Tires

When a car sits too long in one spot, the tires can develop flat spots from supporting the vehicle's weight without movement. Check tire pressure and inflate slightly above the recommended PSI to account for air loss over time. If you want to go the extra mile, consider using jack stands to lift the car and remove pressure from the rubber and rotors.

If you store your car seasonally every year, consider replacing the tires with inexpensive ones and storing your good set elsewhere. This adds an extra layer of protection and saves your quality tires for when you're back on the road.

Use a Quality Car Cover

A breathable car cover is an affordable and effective way to protect your vehicle from dirt, dust, and moisture. Make sure it fits snugly and isn't made of plastic, which traps moisture and can lead to mold and mildew. Whether storing sedans, SUVs, or trucks, always opt for a soft material like cotton or wool that won't scratch the paint.

Covering your car also prevents sun damage to the interior and keeps pests from nesting under wiper blades or mirrors. IA high-quality cover is essential if you're using Uncovered Parking 10x25,

Protect Against Pests and Rodents

Small animals like mice and rats can cause severe damage to vehicles in storage. They chew wires, build nests, and leave droppings that can ruin the interior. Steel wool or rubber seals are used to block off entry points like the exhaust pipe or air intake.

Avoid storing snacks or food-related items inside. You can also set precautions like traps or scented deterrents (peppermint oil, dryer sheets, or even mothballs) in and around the vehicle. Some people place jack stands under the vehicle not just for tire protection but to make it harder for rodents to climb in. Facilities offering Storage Units in Santa Ana often recommend these preventative measures to help protect your car from pests during long-term storage. 

Skip the Parking Brake

It might seem natural to engage your parking brake when storing your car, but doing so long-term can cause the brake pads to stick to the rotors. This can result in problems when you finally drive the car again.

Instead of using the brake, block the wheels with sturdy chocks. This keeps your vehicle stationary without risking internal braking system damage.

  • Check insurance: Confirm your car insurance covers non-driving storage. Some policies offer storage-only coverage that reduces price while maintaining protection.
  • Roll up all windows to limit air and humidity entry.
  • Consider installing a small dehumidifier or moisture absorber inside the interior to reduce moisture and smell.
  • Leave your car in neutral if it's a manual transmission, and avoid using the brake.

Monitor Your Vehicle Periodically

Visit your car storage facility every few weeks to check on your vehicle. Look under the hood for any signs of leaks, nests, or chew marks. Wipe off any dirt or dust, check fluid levels, and boost the battery quickly.

Use a car maintenance app to track when you last checked fluids, cleaned the interior, or changed the oil. That way, you can stay on top of everything, even during long-term storage.

If pests are noticed in your vehicle, inspect for entry points, such as exhaust pipes and vents. If necessary, use traps or repellents to address the problem and prevent further damage.

Can I store my car with the parking brake engaged? 

Using the parking brake long-term is not recommended as it could cause the pads to stick. Instead, use wheel chocks to keep your car stationary.

How often should I check my car in storage if I can't visit regularly?
