[Hallicrafters] Cleaning metal

[TC Dailey]

One of my favorite discoveries is "4-O" steel or brass wool.  "Four Oh" is
the softest one can get; brass being better but harder to find and more
expensive.  You can actually clean up chrome, brass, and other corroded
metals with it, and the microscopic scratches that are inevitable, are
practically invisible.  Take a corroded screw and turn the head inside a
'bush' of 4-O, and it'll come out shiny.  Yeah, I know it's not a perfect
way, but caveat emptor.
