I have wondered on this for a while... I'm always leery to use anything that would be used on plastic materials on bakelite because, as I understand it the chemical make-up is significantly different. So have stuck to water and soap with a toothbrush.
Would like something to bring them to little bit of a gloss if possible.

What has anyone else used or done to them?

thanks.

I have had great results with Novus #2 or #3 depending on how dull they are. I have never damaged a knob this way.

Here's an earlier thread on the same topic you might find interesting: http://philcoradio.com/phorum/showthread...+polishing

I first clean them with purple power (best cleaner I have ever used) then I buff with cheap walmart rubbing compound and a dremel "cloth" cleaning wheel not the fiber wheels. They look like they are coated with wet oil after washing the dry compound off. This also works for scuffed/scratched and yellow plastic dial glass. Todd

I came across this youtube video a while ago on
bakelite knobs.

I have not tried his technique myself but he claims it works very well

It is in two parts, here's the first part:

Thanks folks! I'm obviously underestimating there durability! I read the other thread and it sure looks like the Mothers worked pretty well. I've got Novus as well just didn't want to use it on the Bakelite. I wondering now why i was so leery of using much of anything.

Thanks again ...very good information.

I agree with TAB10672 "I first clean them with purple power (best cleaner I have ever used)"
That stuff works on BBQ grills also!

I've had a cleaner like 409 dull Bakelite knobs before. Now I just spay them liberally with a furniture polish, let them soak, clean any nooks, crannies, or crevices with a soft toothbrush, and they come out looking like new.

Thanks Eliot,
My recollection is something on that order...because of what the bakelite is made out of compared to plastic.
I like the furniture polish idea.

I use Excalbur paste car wax with a soft cloth and minimum of paste.
Also use a very soft toothbrush for the cracks and grooves.

Thanks Chuck ...I was just looking at using some paste wax....the particular ones that brought this up are the thumb wheels on a 42-400 that have dirt/grease in the notches....have to pick up a soft toothbrush. I'm guessing the bakelite is fairly soft...

[Eric Adams]

I tried my wife's ultra sonic cleaner last night (don't tell her). I had to run it three cycles, but it worked great.

[jeffgniffke]

Cool Eric! Trouble with the big consoles it is not easy to remove the thumbwheels is not a simple task so have to do it in place.
