How to Store a Car

Need to store a car? A 10×20 indoor unit fits most classic cars; outdoor parking spaces are another option if you use a quality cover and prep the car first. Here’s how.

Indoor Vehicle Storage

A 10×20 unit is a common fit for passenger cars; some models may need longer spaces. Indoor storage adds shelter from rain, hail, and direct sunlight. Some locations offer climate-controlled buildings that help moderate temperature swings.

Outdoor Vehicle Storage

Outdoor spaces are typically more budget-friendly and easy to access. Because they’re uncovered, invest in a fitted, breathable car cover that straps down well. Park on a clean surface; avoid long stretches under trees.

Pre-Storage Prep

• Wash and dry: Remove road salt and grime to help protect paint and trim.
• Fluids: Change oil if due; top off coolant and washer fluid.
• Fuel: Fill the tank and add stabilizer, then run the engine briefly to circulate. (Do this outdoors and not in the unit you’re storing it.)
• Battery: Disconnect for longer storage. Loose or spare batteries cannot be stored separately inside the unit.
• Tires: Inflate to spec; consider rolling the car a few inches periodically to vary contact points.
• Interior: Vacuum and remove food or anything scented. Crack windows slightly only in controlled environments; otherwise keep closed.
• Cover: Use a breathable, fitted cover—even indoors—to reduce dust.

Organize the Space

Keep a small bin for microfiber towels, quick detailer, and a tire gauge. If allowed, place drip trays under the engine and differential. Store accessories (hubcaps, manuals) in labeled bins—not loose on seats.

Bottom Line

Pick indoor storage when you want more shelter and privacy; pick outdoor for cost and convenience with a proper cover. With a clean car, stabilized fuel, inflated tires, and a connected routine, you’ll roll out ready for weekend drives.

(Reminder: Public Storage maintains no liability for damage or loss to vehicles. Any stored vehicle must be drivable and roadworthy. You cannot store anything worth more than $5,000 in a Public Storage unit.)
