Finally here is my electrolysis setup,,,
I use old lawn mower blades as my anode
And the cathode is what you are de rusting
I bought this large tub at walmart for 10 or so bucks but there are alot better tanks for this than that.
I used baking soda and cheap powder washing detergent and they both work great. You don't have to use much to make it work but I always put in 1/4 of the box and checked it everyday to see how it was doing.
That's about it. Cheap, easy, and clean. Don't worry about electrocuting yourself; unless you drop your battery charger in the tub somehow.
****DO NOT USE STAINLESS STEEL AS YOUR ANODE****
