I used enough water to cover the part. I didnt use stainless, just a steel rod. And i used a small amount of clr.
2 amp setting on charger, part you want to clean should be bubbling, not the rod. I think neg clip on part and pos on rod.
Can add more clr or washing soda if its not bubbling much.
Can use salt too. Part needs to be cleaned and painted immediately.
saw a video where a guy used a welder, a little much in my opinion.
