   It's certainly worth trying Simple Green before you use anything
more drastic.  It's strong enough to get ordinary congealed lubricants
out of a Teletype that's merely dirty.  If there's corrosion, you
might need something stronger.  But at that point you're probably
removing subassemblies for cleaning.  The more elaborate solvents
are useful on machinery that's in really bad shape.

   Simple Green evaporates at roughly the same rate as water, so
you don't have the problem of removing the cleaning agent after
cleaning.

   WD-40 may get things unstuck, but it leaves behind too much
gunk for something like a Teletype.

   Motions in the mechanical teletypes are generally powered in
one direction and spring-return in the other.  Gunky lubricants
in the works generally result in the spring-return actions being
slow, so the machine semi-works but mistypes.
