Better living via chemistry and electrical attraction. Took this rusty Winchester plane iron from a rusty mess to not so bad looking in a few hours. All you need is a battery charger, washing soda, water, some wire and scrap steel. Dissolve a hand full is washing soda in water. Connect the positive to the scrap steel and the negative to the item to de-rustify (invented my own word). Turn on the battery charger and let the fine bubbling begin. Works on rusty gun parts too. Only removes the active rust not in-rusted steel. Do not have any non-ferrous parts it will eat those to nothing. Before and after pics. So much fun you will look for rusty stuff to clean up.
