Think I have done something stupid

What's that on those Zenith radio knobs? I let them soak for hours in a glass with dishwasher detergent and they came out with this yellow goo. Should I scratch this out?
|
Is it actually gooey or is it more like a dry haze? Either way, the soap may have leeched something out of the pores of the material... bakelite?
|
I think it is regular plastic, not bakelite. Anyway, as the hours pass it is looking like it is getting back to normal.
|
abby-normal... ;)

I've had certain materials get hazed over with simple cleaning techniques, but I never ruined them completely. They usually can be returned back with a good buffing.

Curiously, I have never had problems with dishwashing detergent . But never put some bakelite or plastic buttons from TV or radio in a dishwasher because it's too hot . I let them soak in a big bowl of hot water and dishwashing detergent only when I'm in no hurry. Otherwise I clean each button in warm water and dish detergent and an old toothbrush or denture brush simply. Yes of course I let it soak for a few minutes.

I have found that a dishwasher will remove the gloss from plastic or bakelite buttons and knobs, it's too harsh.
I haven't met a knob I couldn't clean up with warm soapy water, an old toothbrush, and a few wooden toothpicks to clean out the grooves. I like to let them soak a while, and then begin to scrub them. I suppose the same as most others here. |

I'll reveal a "secret" excellent plastic polish: Maguire's "Plast-X" It bites into bakelite and with a little elbow grease makes it smooth as glass. I actually us it after Novus #3 and #2, and then a buff with #1 with cheesecloth. |
Really gunky knobs I clean with a toothbrush and either Goop hand cleaner, or a liquid cleanser like Soft Scrub - basically a finer abrasive than Comet and in a liquid form so less abrasive.
