I tried lots of different types of cleaners, trying to get old built up wax off the trim of my car. Up to and including WD-40 (didn't work very well, lol). Out of all the cleaners tried, this Back to Black Heavy Duty Trim Cleaner did the job. I waited a bit before doing this review to ensure that, like most of the others I tried, this one did NOT cover the wax. It actually took it off instead of covering it up.
