I'm currently using McGuire's Mirror Glaze 9, "professional swirl
remover 2.0". *It does the job and provides a permanent finish and is
easy to find.

I use a buffing wheel, but run it with a variac at lower RPM's so as
not to burn the knobs/plastics, etc. I just use the white buffing
stick for rouge and it really brings stuff upto a really nice shine.
Of course I have two buffing wheels, one for plastics and the other
for metals, never use the metal one on plastics!

Thanks for all the great ideas. I am going to order the Novus Plastic
Polish #2 from Antique Electronic Supply. That seems to do a great job
for a lot of different plastic items. I will give that a try on the
bakelite knobs.

Hello Randy
Have had good results with gloss black two pack automotive paint such as
Acran. It is a bit expensive here but seems to be both good looking and wear
resistant. Have also used it with many coats to replace that plastic dip
that is used on aircraft control yolks

I just polished some up with the plastic polish and it really came out
nice, maybe a little too nice. It looks like a brand new knob on 50
year old equipment. I would like something that gets the dirt off but
leaves a little age.

For all my old equipment, I remove the knobs and any screws, then give
them a good cleaning with a tooth brush in warm, soapy water. I use a
mild liquid soap like used to wash cars. They come out very nice
without being "too nice."
