Why it is effective: Should you let a spill or a stain linger for any period of time in your vehicle, it quickly becomes "personality" and is impossible to eliminate. Remember that time when Jim smacked his head on the doorframe and got blood on the armrest? Of course you do, now it's a stain and because you did not clean it up straight away you never have the time or the wherewithal to scrub away.
Don't eat in there
Why it's successful: If you're able to avoid eating in your vehicle, you wo not need to deal with all the wrappers, cartons, stains and crumbs that inevitably follow.
You can find these anyplace. And for good reason; they're wonderful at helping maintain your automobile organized and well-stocked. Keep one in your back for shopping bags groceries, and sports equipment. Hang one on the rear of the seat stuff: sippy cups, books, toys, and other essentials they need to get an automobile ride.
Keep it clean so it stays clean

Similar to the dirty laundry analogy: If you have one set of dirty socks on the ground, it's a lot simpler to place that second pair there, then the third, then the... Finally it becomes a mess. Additionally, if your passengers visit a clean car, they will notice and tidy up after themselves, not to mention compliment your ride.
