Another solution that my Dad uses on a regular basis for "de-rusting" old tools is to submerge the parts in white vinegar. He uses an old cast iron kettle and has a piece of electrical conduit laying across the top with coat hangers used as hooks to suspend the parts and ease their retrieval. I've used a paint can for small parts. Works surprisingly well, but it will take a day or so for surface rust. A week or two on a badly rusted part. Might I suggest that you find a place outside that you can cover the container and avoid stinking up your shop. The vinegar "bubbles" so I'm guessing that you wouldn't want to seal it up tight. Hope it helps.
