What is the best way to clean cigarette smoke residue off these vintage radios?

Thanks, Phil

Murphy's oil soap or any soap that is not harsh. Detergents like 409 can strip away the thin layer on some Bakelite's. The stripped surface will be very dull, sometimes exposing the filler, extremely difficult to polish if at all. This is deceiving as the stripped off phenolic looks and smells a lot like nicotine.

For wood cabinet, Murphy's is fine, do not soak, some folks like to use GoJo nonabrasive hand cleaner, use method, wipe on, wipe off. If the lacquer is tight and not flaking a wood cabinet can be refreshed with a polishing oil...

YMMV

Depends on the surface but you might try the original Gojo on cases and Windex or alcohol on chassis. Do not get cleaners like that inside of pots or volume controls. That stuff cannot do much damage to any other parts as long as it is dried out with moderate heat. I would apply the Windex to some rag and wipe if you cannot control where it will go otherwise. Pure alcohol at least is not potentially corrosive like the ammonia in Windex and evaporates easily enough. Windex and liquid cleaners can potentially remove markings from tubes and reverse painted glass dials. Pays to use something gentle on the painted side of a dial but the front is OK with glass cleaner. Knobs can be washed in warm water with hand soap and an old toothbrush, rinsed, and dried well. It is sort of situational, though, nothing is best for everything.

After a fire at our church, everything got wiped down with these:

We also had them in the Navy, for emergency reclamation after a fire. Vent systems like to pick up smoke and deposit it everywhere. Those sponges worked wonders. No liquids involved, but if you have a nicotine film, a mild solution of Murphy's works great.

I have had real good results with the 25 sheet packs of electronic wiped they sell at the dollar store. Seeing tar and nicotine lift off is gratifying. These work really well, and 25 for a buck? Hard to go wrong.

I use Greased Lightning cleaner from the dollar store on my bakelite sets. It eats nicotine like nothing else and cleans fast. $3.00 for a big bottle of it plus its safe on plaskon and bakelite sets.
