After  restoring five Teletype machines, a few comments.

I start with  cleaning, using a soak in Simple Green
and de-ionized water.  2-3 days  may be necessary just
to get dirt and oil off neglected machines.  Rinse
with de-ionized water, so as not to leave crud  behind.

Evapo-Rust is very effective.  It's not an acid; it's a  chelating agent. 
It attacks oxides, but not metal. It will remove  Parkerizing, an 
anti-rust coating applied to many Teletype parts before  assembly, so
don't use Evapo-Rust unless you have to.

For un-jamming  stuck parts on shafts, I've used Loctite Fast Acting 
Corrosion Freeze and  Release Spray. This is a mixture of freeze spray
and penetrating oil. The  freezing process will shrink metal slightly,
opening up enough space for  the penetrating oil to get in.
This is effective in about two  minutes.  I wear eye protection,
gloves, and a volatiles respirator  when using this stuff.

I've used carburetor cleaner on a gummed up  selector. It worked.
