I have had this problem with many cars and don't really know how to fix it. I can't remember if I had this problem with my NSX or not, but thought it would still apply here too. How the heck do you get the wax build up off of a vinyl, rubber, or plastic strip/piece on a car? I have tried rubbing alcohol, formula 2000, etc. I try to be careful around that stuff, but still somehow end up getting a little on there and it leaves a chalky white residue that doesn't come off. Any tips on how to fix this would be appreciated?
