Here is an answer from a bakelite radio knob restortation from this post:
LINK "If the knobs are Bakelite, petroleum solvent stripper will remove the varnish. Like 5F5 or Strip-ease, etc.
If the knobs are some other kind thermoforming plastic then try an organic such as a lye based stripper or drain cleaner.
Orange based strippers are somewhere in between and may soften or craze if it is NOT Bakelite.
Always try a small daub of the stripper on the backside of the knob and leave it long enough to prove suitability.
I would suggest boiling water with Simple Green but that may deform some thermosetting plastics. It would ruin Tenite and craze Bakelite.
Good Luck!
