Evapo-Rust is seriously amazing stuff. I can't say enough about it. It's a soaking rust remover. Safe, non-corrosive, and re-usable over and over. No effort required. Just soak. Only downside is you have to be able to soak your rusty item in it. So if it won't fit in a big tub or container, it's hard to use. Buy it at harbor freight or many auto parts supply stores. Like $34 per gallon. Expensive...but remember it's re-usable many many times.Dave Paine said:If superficial, the Kenbo and C'man methods work. If the rust is deep, then search in the Hand Tools forum for tool restoration threads where they have used Evapo-Rust or Oxalic Acid or Electrolysis.
