Re: 2 ?'S. Rust removal by electrolysis.
I cleaned 6 stanley planes and several chisels using the battery charger electrolysis method and it worked very well. I used a cheap stainless steel tray as the anode. I understand that surface pitting can happen if the process is allowed to go too long. Just monitor the progress daily and stop when the tool is clean. And yes, cleaned surfaces will re-rust right before your eyes, but the rust is easily removed with fine sandpaper.
