creamy Peanut Butter will take off all of that dried up wax off of your plastic trim pieces and moulding. Its an old detailers trick but it gets all that stuff right out. I just use a paper towel and lightly rub the area with just a dab of peanut butter....... works every time.
no, Im not kidding, but thats the reaction I get almost every time I mention the peanut butter trick. Just put a little bit on a paper towel and rub it lightly across the black trim with the wax stains..... then come back and tell us how well it worked
