So, we.'ll need a pack of chemical soda. I used one pack per bucket.

Take that rusty car part, that you want to clean up from rust and some kind of another iron part, that will infuse rusts of the good part.
Also you will need an accumulator (battery) charger.

Connect the chargers plus (+) wire to the part, that will attract rust and minus (-) wire to the good but rusty part

Fill the bucket with water, put both parts into it, but that they would'nt touch each other and start the charger.

Last thing that you should do is to clean the good part with sandpaper or something rough like that,to take off the top grey coat and you are done!
Hope that will help
