Waxed the E but got some spots of wax residue (whitish spots). The ideas to prevent this will definately be utilized moving forward. But I do need to get rid of the wax already on the plastic. Any tried and working solutions to this delemma? When I apply Turtlewax 2001 plasticl/rubber conditioner , the spots fade away. But over the span of a week, the same spots reappear.
