I got an external modem that has corrosion/staining/discoloring on the top.
I’m not sure how to polish it off, so the case looks close to new.
Furthermore, I do not want to shine it up to a mirror finish. I just want the cool brushed aluminum finish back.
I do not know what has caused the stains. But it probably happened long ago in bad storage.
I can not swap cases with another unit. The labels on the bottom are not easily removed without damage. I tried on a 'test unit'. They warp up with heat, or curl up just pulling cool, and give off a very had smell.
Thoughts
Thanks
