Well for my electrolysis I actually use a chemical called Sodium Carbonate.In a 50 litre bucket of water.I do use a stainless steel anode and a car battery charger.As per a manual I have to do this procedure.With this mix some items can be done in as short as an hour.For the badly rusted items yes it can take longer.In the manual I have it suggest that use use a Stainless Steel anode for better conduction.I certainly have had no problem with it,and I would recommend it to anybody who is thinking about it.Much easier especially for those hard to reach areas.Also save a lot of sanding.I hate sanding.
