You can remove rust from metal by soaking it in a mixture of feed grade molasses and water. Ive removed rust from washers, bolts, brake rotors, auto body parts, and more. Be sure to paint or treat the surface after rinsing to avoid flash rusting.
It is important that you use a sulfured molasses, which most often can be sourced from an agricultural feed store. I typically use a 3 parts molasses to 1 part water ratio for rust removal. (Hot water works best to dissolve the molasses) Submerge your rusty parts in the solution and check back in 2-3 weeks. Severely rusty parts will require additional time. The solution can be reused, but Ive noticed that it smells like it is fermenting after 2-3 months.
