DIY Rust removal

DIY Rust removal, Mikey writes-

I was looking around instructables the other day and saw a great howto about rust removal using electricity. “Hmm”, I thought to myself. I sure like to electrocute things. My neighbor gave me a rusty pipe wrench which came out impressively rust free after a few hours of soaking. I used a 12V .5A power supply and attached the negative end to the pipe wrench and the positive end to a old piece of steel remesh. Both pipe wrench and remesh were put in a bucket of water that had some baking soda. After a few hours of bubbling I removed the pipe wrench and let it sit for a hour in a vinegar bath.
