Keep it clean and coveredWhether you're driving your car every single day or only once every couple of weeks, the golden rule remains: a clean car is a happy car. Cleaning up the car's exterior with automotive soap, polish, and/or wax not only keeps it looking nice, it helps prevent the onset of corrosion and grimy substances, the ultimate enemies of any vehicle in short- or long-term storage. In addition to the exterior, you should give the interior a thorough cleaning as well to prevent dust buildup and ward off pests like bugs and mice. Whenever you do finally take your car for a drive, the last thing you want is to climb into the driver's seat and have a massive cloud of dust fly up into your face.Besides periodic cleaning, it might also be to your benefit to get some manner of covering for your car, doubly so if it's parked outside. Placing a cover on your car helps to protect it from damage from the elements while still allowing for a reasonable amount of airflow. If your car is left in an outdoor parking lot, you never know what kind of scratches and bumps can accumulate while you're not paying attention to it — a cover will help to protect it. Granted, you'll have to take the cover off to drive it and put it back on afterward, but this is less of a chore if you're only driving once in a while.Start it up once in a whileOne of the nice things about owning a car is that you don't always need a reason to take it for a spin. You can just start it up and take it out of the garage, even if it's just to take a quick lap around the neighborhood. In fact, doing this is actually good for a car you're not driving regularly because it gets the components moving and helps to loosen up its fluids.If you've got the time, you should try to take your car out for a drive at least once a week, even if it's just for a 15-minute jaunt around the block. Starting up and rolling your car around will ensure that any components that have been sitting dry for a long time don't get completely crusted over with rust or stuck in place, as well as circulating fluids like coolant and oil. You should be especially considerate of your car's brakes, as the rotors may have accumulated corrosion or grime while they weren't in use. Make sure you pump the brakes a few times during your little jaunt so they can shake off the crud.Incidentally, just for the sake of saying it, don't just start your car and leave it idling in the garage. Not only will that not help the internal components, it can lead to extremely dangerous carbon monoxide buildup.
