Thank you to Brad B. I used PB on my black wax stained trim. It worked. All the wax residue is gone. It's been 10 days, and no sign of it returning(touch wood). I just spread it on with my fingers, and wiped it off with a towel and then car washed it. Dawn and rubbing alchohol did nothing to remove the stains. PB was my last on hand solution. It also removed the stains that were left by the mothers back to black i used all of 2x. My trim looks like the day I got the car. Forget 303 and EF Black opal, I'm using PB to dress my black trim.
