Does anybody else use electrolysis for rust removal? Depending on what I'm trying to remove rust on, I use all chemical methods listed here and electrolysis for the larger parts with really heavy rust. For those that dont know: http://www.instructables.com/id/Electrolytic-Rust-Removal-aka-Magic/

I like Evaporust the best though... sometimes I simply cant believe that the part that comes out is the same part that I put in!
