These are before and after images (well technically after and before images) of the rear cylinder exhaust manifold on the Virago. I built an electrolysis 'tank' out of an old rubbermaid bin to remove rust from the old manifold. I left it 'bake' for about 5 hours and saw really great results. I plan on using this method on other items such as that stubborn subframe pin, motor mount bolts, etc. Here's some pics of the tank setup.
Basically you use 4 pieces of rebar as the 'collecting' rods. Those are charged with the positive lead from a battery charger. The piece to be de-rusted is connected with steel wire to the negative lead. The water is filled with Sodium Carbonate to make it more conductive. The passing of electricity extracts the moisture and rust from the steel and moves it toward the rebar.
