I tried as we usually do it to mix a liquid dishwashing soap with hot water and soak the knobs and then scrub it with toothbrush.

Zero effect on that gummed up skin oil plus dust......it is lodged well.

A sharp object will take it out but I do not want to scratch the backelite.

Are there any solvents I could use?
WIll GoJo do it? I would use it but I do not know if it affects the backelite in an adverse way.
