Hi all. I have a 2001 Mustang GT convertible, and no matter how much I clean the interior of my car, I cannot get rid of that plastic-y smell out of my car!!! I've used a 15:1 OPC mix and the seats and panels are spotless but that smell remains... I don't know if anyone knows what I am trying to describe, but it's almost smells like plastic toys from the 90's... PLEASE HELP!!
