First, I would send that crankshaft to Racers Toy Store or some other shop that deals in vintage cranks to have the
crank rebuilt with a new big end bearing. While it's apart, they can clean the halves and media blast the rod and
resize both ends. I don't know what else you have that is rusted, but WD40 Rust soak works great on steel parts.
Just put everything in and soak over night.
You can do a lot better than DC plastic. Try this site:

The ultrasonic parts washer will be useless for 90% of what you're doing at this stage. Once you get the steel parts
rust free, the Aluminum parts media blasted, all the paint and other crap off, you can start thinking about using it.
You will need to acquire metal specific cleaners to use in that kind of washer. It is great at cleaning carb bodies,
removing media and grit from freshly honed cylinders, etc.
If I were you, i would concentrate all of my efforts on getting that basket case engine running again. If you start
going in all different direction with shocks, plastic and other minutia, this project will get out of control in a hurry.
