This might be of interest to some. My neighbor down the block is
restoring a 1969 GM pick-up truck, and brought me the vintage radio
from it to see if I could do anything with it. He had *NO* interest in
converting to FM, much less stereo, all he wanted was to get the AM
back.

The radio looked like it had been ridden hard and put away wet each
and every day since 1969, fully encrusted with filth, grease, what
looked like melted sugar, plastic and more. To the point where the
tuning knob was locked, as were the preset buttons. This is a
solid-state radio, not tube, of course.

I took the attitude of kill or cure, so after partial dis-assembly,
removing the top and knobs, I put it on the top shelf of the
dishwasher (Bosch) and ran it through a full scrub cycle (alone), then
dried it in the oven for 2 hours at 175F. It came out sparkling clean,
and with (thankfully) the back-painted numbers on the dial intact.

What's that in Centigrade - apparently germanium transistors brew up
somewhere around water boiling point.

Boiling point is 220F.

Nice story

Where do you live, the bottom of a lake? 212F at 1 bar!
