But honestly I still stand by cleaner wax and an orbital. This is one instance where I've learned to just move past the least aggressive method first...when i can pick up the PC and a chemical cleaner with wax in it and one step the process instead of cleaning and then going back to wax later...win / win for me. Plus some of that track rubber can be really stubborn and if you're doing anything other than lightly rubbing the surface even with a microfiber towel you're scratching it in the process.
