How to Prepare Your Car for Safe Storage for Several Months
Practical steps to safely store a car for more than two months while avoiding battery, tire, and fuel system damage.

The short answer
- A completely dead battery when trying to start the car after long-term storage
- Leaving the battery connected without disconnecting or trickle-charging it long-term
- Wash the car thoroughly inside and out, ensuring no food residue that could attract rodents
- You can disconnect just the negative terminal to prevent gradual drain, or better, use a permanently connected trickle charger that keeps a full charge without needing to manually disconnect anything.
Background
Storing a car for several months, whether due to extended travel or temporary non-use, requires more than just parking it and walking away. The battery gradually loses its charge, tires can develop flat spots from sustained weight on one point, and old fuel can degrade and cause problems upon restart. Rodents also find a parked car an ideal nesting spot, chewing through electrical wiring. Following proper preparation steps before storage protects the car from these issues and ensures a smooth restart when it's needed again.
Numbers first: what you'll pay
Preparing a car for safe storage typically costs SAR 100-300 ($27-80) including fuel stabilizer, a trickle charger, and a car cover, while skipping these steps can lead to repair costs exceeding SAR 1,500-4,000 ($400-1,070) for replacing a ruined battery, cleaning the fuel system, or fixing rodent damage to wiring.

How to spot it yourself
What actually causes it
- Leaving the battery connected without disconnecting or trickle-charging it long-term
- Not jacking up the car or slightly overinflating tires before long-term storage
- Storing the car with a partially full fuel tank and no fuel stabilizer
- Not cleaning the car or leaving food residue that attracts rodents and insects
- Storing in a damp or poorly ventilated place that promotes mold growth
Step-by-step inspection plan
- Wash the car thoroughly inside and out, ensuring no food residue that could attract rodents
- Fill the fuel tank completely and add a fuel stabilizer to prevent fuel degradation
- Disconnect the negative battery terminal or use a trickle charger to maintain its charge
- Inflate tires 5-10 psi above normal to reduce the chance of flat-spotting
- Jack the car up onto stands if storage will exceed 3-4 months to fully avoid tire damage
- Place rodent deterrent or wire mesh around air intakes and exhaust openings
- Cover the car with a breathable cover that protects it from dust and moisture without trapping heat
Prevention
If the storage period will exceed one month, follow the full preparation checklist, and if possible ask a trusted person to run the car for 10-15 minutes every two weeks to maintain battery charge and circulate fluids, avoiding storage in a spot exposed to direct sun or high humidity.
Quick answers
Should the battery be fully disconnected when storing a car?
You can disconnect just the negative terminal to prevent gradual drain, or better, use a permanently connected trickle charger that keeps a full charge without needing to manually disconnect anything.
What is tire flat-spotting and does it go away on its own?
It's a temporary or permanent deformation at the tire's contact point with the ground from sustained vehicle weight; minor flat-spotting disappears after driving a few kilometers as the tire warms up, but severe flat-spotting after many months can be permanent and require tire replacement.
Should a fuel stabilizer always be added before storage?
Yes if storage exceeds one month, since regular fuel begins chemically degrading and losing properties after 30-60 days, and a fuel stabilizer slows this degradation, keeping fuel quality intact for additional months.
How do I protect the car from rodents during long-term storage?
Clean the car of any food residue, place rodent deterrent (like mothballs or peppermint spray) around air intake openings, and consider putting protective mesh over exhaust pipes if storing in an area known for rodent activity.
