A scotch brite will give it a brushed look. If you wanted to do this, I think the best way is to polish it first to a mirror finish, and then very lightly run the scotch brite pad over it almost so lightly that you don't think its doing anything. Repeat numerous times, always moving the pad in the same direction, and you will end with a perfectly brushed look.
Edit: whoops, i was talking about the actual tube, not the contacts. Yeah scotch brite would be perfect for contacts... Or a small file.
I really just wanted a thread with these keywords in it; now it exists, with super answers. You guys rock, keep it coming!It really depends on what you bought! Some mechs like REO you can throw in the sink and wash ... others you may want to just clean the contacts, the threads, naolox the threads, etc.
If you tell us what you bought then it will help.
