Question Regarding Wheel Cleaners

I have a 92 Toyota Supra with wheels that are in need of cleaning. I have used several different products in order to remove the caked on brakedust and grease, but none have worked really well. I just picked up Black Magic Wheel Cleaner and it has done a lot better than every other product I've used. It looks great on the other newer cars here, but the brakedust on my wheels must have been for too long a period of time and I am having a lot of trouble with them. I'd like to keep these on my car, but I really would like the wheels to shine and stand out. Are there any products out there that any of you recommend for caked on grease, or are there any other things I can get/do that will make them shine again? Thanks in advance.
