How to remove interior plastic scratches in the Scion xB?

I have a small, not so deep scratch on the interior plastic of my 2010 Scion xB and was wondering how to remove it. I've heard of using vaseline, the mr.clean magic eraser, and something called a "whitestick". Does anyone out there know what would work the best out of these products or any other that is known of?? Thank you!!
