Nice machines and cabinets. My Dad restores old rusty engines and gets them running again. He helped me get an old Universal running that was rusted up. We used "Rust Off" and WD 40. He said both are equally good. It helps to let them sit awhile after you put the spray on. It has really cleaned things up and got screw to turn that wouldn't before.
I am from south western Kansas; are you?
