Best to use the high test (20% & 30%IIRC) acetic acid/vinegar which is used as a pesticide/herbacide. Be careful handling it. It's potent. You can get it from most garden supplies or AMAZON. About $22/gallon.
Works great on rust. Strip any paint and degrease. Let it soak. Nuetralize and buff with a wire wheel. I cleaned the rust off some pretty knarly tools with the solution. Same for electrolysis.
