After trying assorted techniques suggested in the forum to no avail, the one that worked for me was mineral spirits. I applied the mineral spirits with a paper towel. Car was split into 1/4's. I used a medium brush and scrubbed each spot. I let the most stubborn stains sit a few minutes before wiping. Each spot was wiped with a very wet towel (make sure water washes mineral spirits off of plastic and any metal. I then applied "303" aerospace plastic protection (it was $12, time will tell if it's more durable then the $4.99 Tutrle Wax 2001. I WILL BE VERY CAREFUL WHEN WAXING IN THE FUTURE. WAX STAINS ON THE PLASTIC ARE VERY DIFFICULT TO GET OFF. PREVENTION IS DEFINATELY ADVANTAGEOUS. Hope this may help someone
