About a year or two ago someone on the wreck posted about how to use electrolisis to clean up a rusted plane (or any iron). It sounded cool so I saved it. A few weeks ago a friend who was moving gave me an old Stanley #4 that had been his father's. It was in pretty bad shape, rusted and all. I remembered the article and pulled it up. WOW! I can not believe how electrolisis cleaned up the rust. It is like it took the rust from the plane and put it directly on the old scrap angle iron I used as the sacrificial plate.
I never bothered to save the name of the OP, but you know who you are. Thank you.
