Radio cleaners,

Here is some lore from the folks who restore antique radios (including those
metal cabinet Atwater Kents with the heavily wrinkled paint):

The cleaner of choice is NON-abrasive Lemon Go-Jo.  Repeat, NON-abrasive. You
glop it on and scrub with a toothbrush or better yet a real "hospital brush"
(fingernail brush). scrub with moderate pressure in small circles.  You'll see
lots of dirt loosened up. Clean off with paper towels, and maybe Windex.  Then,
REPEAT the whole thing.  You'll see more dirt loosened up.  A third cleaning
may get even more dirt out.  

Finally, clean with the brush lightly with Windex. Wipe with cloth or paper
towels.

THEN, if you like, apply bowling alley wax, butchers wax, or for ultimate
protection, Renaissances Wax (Expensive, but developed and used by top museums
in England.)

DO NOT use Armor-All.  It  has silicone in it. That means your antique radio
will LOOK good - for a while, but may attract dirt and dust and cannot be
cleaned again.  Silicone compounds are best removed with solvents/cleaners that
have been removed from the market due to environmental regulations.

(I can neither confirm nor deny that I have a small quantity of the legendary
Cramolin at my place.)

Good luck.
