Restoring old black knobs.
 
Anyone have some ideas on restoring some old black knobs to the
original glossy finish? These are the black knobs possibly made from
bakelite? used on the HQ-170 receiver and many other old boatanchor
type equipment. I have a couple of the knobs on my old AT-1 that have
gone dull and I would like to return them to the nice glossy finish?
Thought about cleaning them real well and then spraying them with some
type of clear glossy finish? Possibly there is a better idea out
there. Thanks & 73, Randy, w5kcm

Hi Randy,
I have used repeated applications of motor oil on my Collins bakelite knobs.

Hi Randy,
I have used Amorall successfully to bring back the luster on both
knobs and black wrinkle finishes. KF6KXG Mike

I use a buffing wheel and jewelers rouge. After buffing, you may use
automotive wax for a nice shine.

The problem is that the surface gets etched, and you need the surface to
be smoothed out. Green jeweler's rouge on a rag and a little elbow grease
will do wonders.

I tried toothpaste... it is too fine. Just takes forever. Might be okay
to use toothpaste with a buffing wheel but definitely not by hand.

The "official" stuff here on Airstrip One, is called "Paste, Polishing, No.5"
and originally used by the GPO for cleaning Bakelite telephones. It's also
sold commercially as "Bake-O-Brite" ore somesuch, and can usually be found
on eBay.

Basically it's a wax polish with a mild abrasive added.

I wonder if automobile rubbing compound would work. This
is used for restoring badly oxidized finishes or for
painting where several coats of laquer are to be used.
Its sold under many brand names and can be found in any
auto parts house and most hardware stores.

Please don't use motor oil, WD-40, Armorall, wax, etc. Those are temporary
coatings which must be reapplied and actually attract dirt over time.

Use Novus Plastic Polish #2 and a soft toothbrush, followed by brisk rubbing
with a soft rag. The shine will last forever.

Available from many online suppliers, such as Antique Electronic Supply,
http://www.tubesandmore.com/ .

I have used #2 to polish hundreds of radio dials, knobs, bezels, etc.

Don't use #3 -- too abrasive for most situations. I also don't have much use
for #1, which is more of a protectant for something that's already shiny
(and could be cleaned up just as well with mild soapy water or Windex).

If you clean and polish the knobs correctly, there is no reason to spray
them with any sort of new coating. The knobs were not sprayed with stuff
when the radio left the factory.
