Rust dip success stories?

I have an electrolysis tank I made from a 5 g bucket. Used graphite sacrificial anodes, water/washing soda medium and a battery charger. You have to have it hooked up right, plenty of vids on YouTube. Run it overnight and good bye rust dirt paint whatever. Learning curve to it, but it works. No corrosive medium.
Ill blast chrome right off a wrench too if you have it hooked backwards. Use the chrome wrench as the anode. I did a cylinder head as described and I didn't have much luck with it. Used SS as the anode.
