Connect the Negative lead to the part that you want derusted!!!
-for the solution: About a tablespoon of household / washing soda to a gallon of water. (Fine bubbles will rise from the object when cleaning is in progress)
-after some hours scrub with Scotch Brite , rust scale is loosened and can be easily removed. Un-rusted metal is not affected in any way.
