Protect your car from pests. This means closing all air vents and blocking your exhaust pipe with steel wool to keep small animals and insects from getting in and making themselves at home. You can also try placing mint leaves or mothballs around your vehicle to deter pests.
Keep the interior dry and odour-free. Consider placing silica gel packs or another desiccant (dryness-promoting) product inside your car to prevent dampness from settling in. You can also place a container of baking soda on the floor inside your car to absorb odours and prevent the air from going stale.
Park the Car on Jack Stands
When a vehicle is parked for an extended period, its weight can cause flat spots and tire deformation, which could require tire replacement. To prevent this, park the vehicle on jack stands at all four corners, and inflate the tires to the recommended pressure.
