I recently put some used cans on my bike and they have some rub marks where the old hangers where on the previous bike. It's not a huge deal but it's enough to bug me. Do you guys know of anyway to clean these up? I may be down for going ahead and doing a full polish on them but I'm not sure if I can considering they're titanium. I tried using some Mothers polishing compound on them just to see what would happen but it didn't really make much of a difference. I pretty much just want them to be a uniform color without having to resort to paint.
