almost free rust removal using battery charger and washing soda?

GSS340 said
I just tried the battery charger baking soda thing on one of my parts, its only been in there a couple hours but its bubbling and the rust is moving off the part...I guess I'll leave it in for a couple days and see what happens

Got a question though...Is the electrolysis turning the baking soda water into an acid; something I don't want be dipping my hands into?

It shouldn't, the soda is very alkaline, but don't forget about the part, keep checking on it every few hours. TO be safe wear gloves when sticking your hands in it, if you go too extreme either side of neutral, it could harm you. Just be carefull.
