Wire wheel, some sort of acid...whatever you prefer. I wire brushed all of my stainless for my glass (front, sides, rear) with a bench grinder to clean it and then mounted a couple of buffing wheels to polish it.
Be very careful if you don't have a lot of experience doing this. If you catch the trailing edge of the trim on the wheel, you WILL have a problem. Best case scenario, it scares the crap out of you and might bend the trim. Worst case scenario, the wheel grabs the trim and throws it into a soft part of your body.
Keep in mind, a 6" wheel at 3450 rpm is moving at 60 mph.
