If you’re too lazy to clean your car on a regular basis but still hate the mess, Jalopnik says, an ounce of prevention is worth a pound of cure. First, don’t eat in your car so that trash and stains never get the chance to build up inside. Don’t let kids inside your car, and if you must, be vigilant against the spills and trash they can bring. Waxing and garaging a vehicle reduces the need for exterior washes, and having a trash bag handy inside can keep detritus to a minimum. Finally, each time you exit the car, take something with you; whether it’s a piece of trash or something useful that shouldn’t be in the car anyway, it will help keep the car’s interior clean and clutter-free.
