Hey guys, I just found my first single-wide display case. I'm sure you're familiar with the 4-shelf X-Metal case. It is in really nice shape. I had a question about the aluminum vertical corners. What do you use to clean up the aluminum. So far I've tried a Mr. Clean Magic Eraser, a No-Scratch (blue) scrubbing pad, Goo Gone, Car Cleaner Wax, and extra fine steel wool. The steel wool seems to be the best so far. The Magic eraser does help a little, but the steel wool seems to be more effective. Do you have any suggestions for cleaning up the corner rails of this case? I already order the plexiglas restore the door and possibly the "walls". Any advice would be welcomed.
