Leaving your car parked for a few months without getting it ready can lead to dead batteries, rusty parts, and unwanted pests. Whether you are traveling, storing a seasonal ride, or keeping a second car safe, taking a few simple steps now will save you a lot of headache later.
If you live anywhere near the coast, humidity and salty air make rust (coastal corrosion) happen much faster. Here is a simple checklist to protect your car while it sits.
Step 1: Clean the Outside and Block Pests
Dirt and bird drops left on your car will ruin the paint. Sea air and moisture will rust the underneath.
- Wash the Car Well: Hose down the underbody and wheel arches to remove dirt and salt. Put on a coat of wax to block moisture.
- Keep Critters Out: Mice and rats love to sleep inside quiet engines and chew on wires. Plug your exhaust pipe and air intake with steel wool. You can also place peppermint-soaked cotton balls around the tires and under the hood—pests hate the smell.
Step 2: Fresh Oil and Fuel Care
Dirty oil contains acid and water that slowly eats away at your engine parts over time. Good engine preservation starts with fresh fluids.
- Change the Oil: Put in fresh oil and a new filter right before storing the car. Drive it for 5 minutes so the clean oil coats all the engine parts.
- Add Fuel Stabilizer: Gas goes bad in 1 to 2 months. Pour a bottle of fuel stabilizer into your gas tank, then fill the tank up completely. Drive for a few minutes so the treated gas reaches the engine.
- Top Up Other Fluids: Make sure your coolant, brake fluid, and windshield washer fluid are full.
Step 3: Battery and Tires
A car battery will go dead in a few weeks if left plugged in because of the alarm and electronics inside the car.
- Use a Battery Tender: Connect a smart battery tender (trickle charger) to keep the battery alive. It automatically keeps the charge full without damaging it. If you don’t have power nearby, disconnect the negative battery cable.
- Pump Up the Tires: Fill your tires to the maximum PSI written on the tire wall. This keeps them from going flat on one side.
- Don’t Use the Handbrake: Leaving the handbrake pulled for months can cause the brake pads to stick to the wheel rotors. Use wheel chocks (blocks) behind the tires instead.
Step 4: Clean the Inside
- Clean Up Food: Vacuum up all crumbs and trash so you don’t invite bugs or mice.
- Stop Mold: Put a couple of moisture-absorber tubs on the floorboards to catch damp air and stop mold from growing.
Safety First Before You Start the Engine
When you come back to your car, keep these basic safety rules in mind:
- Never run the engine inside a garage or storage unit: Exhaust fumes contain carbon monoxide, which is odorless and deadly. Always roll the car out into the open air before starting it.
- Don’t turn it on just for 5 minutes: Unless you are going to drive the car for 20 to 30 minutes to get it fully hot, do not turn it on. Short runs create water inside the exhaust and engine, causing rust.
