I know that paraffin (kerosene) washers are used in the car industry.
They have a short metal hose over a grid in a round enclosure. A pump moves
the paraffin up through the hose.

I worked for an office equipment store back in the

concrete laundry tub filled with kerosene or some similar solvent, with
some metal racks in them. Any major repairs to typewriters or mechanical
calculators was proceeded by a dunk in the solvent, perhaps over night.
I think they used the other half of the sink for a second dunk. Might
have been more kerosene or maybe kerosene with a small amount of light
machine oil dissolved in it. They only dunked the metal parts. I'm not
sure if the removed each plastic key first or not-- maybe they did.
I've been thinking along those lines for my ASR33. It's got a lot of
old sticky lubricant all over the typing unit, and I heard recently of
one that was dunked. Mine doesn't always work reliably when it's cold,
but usually is OK after running for a while and has warmed up.
What do people think about that? My feeling is it wants a good clean
and a proper re-lubrication, and cleaning would be easiest by the
"dunk". Obviously a lot of electrical or plastic parts want taken off
first (the motor, for example!).
