Rust Removal using Electrolysis

I don't recall any systems per se, but if you attach a ground strap to the chassis and let it drag it will provide a discharge path for all the static buildup acheiving the same effect. I remember the city using this process on all their equipment when I was a kid. I always thought something was loose until I knew what it was. You just need keep an eye on the length over time, it will grind away.
