If you get by the grocery store, buy a gallon of white vinegar....it's cheap. Get some rubber gloves to work in, and a few red scuff pads, and try scrubbing the surface rust off with the white vinegar. You will need to neutralize it with baking soda if it cleans the rust off, or it will flash rust back. I soaked a surface rusted crank in a 5 gallon bucket full of white vinegar, and it came out looking brand new. Maybe it will work on that surface rust also.
