I try to use the least aggressive method necessary to get it clean. My method would be to start with naphtha and see what it removes. If not enough, move on to Novus 2. That was all it took for my Travel Time. Big hit needed more, so I went at it fairly aggressively with magic eraser. After ME, I go back to Novus 2 to shine it up. Last step is always carnauba wax.
