Tight crevices and beveled edges are common in car design. Unfortunately, dust and sticky crumbs make them a headache. To clean these areas, wrap a tissue around a toothpick and have at it. Toothpicks are also good for gently loosening paint chips that are still stuck to the exterior. You can even use a little touchup paint on the end of a toothpick to address very tiny imperfections.
