Classic Plating
Electrolytic Rust Removal and Zinc Plating
Home > Visual Aids > Electrolytic Cleaning
This is by far the easiest way to clean rusty, greasy painted parts with little or no damage to the part being cleaned.
The kit contains two electrolytes. One for iron and steel and the other for softer metals and alloys. The kit contains chemicals to make up to 60 litres of electrolyte.
Suspend the items in the tank, as for plating. Note the electrodes are reversed. Positive to the item you are cleaning and negative to the steel elecrodes. Use enough current to get a healthy rise of bubbles. It doesn't have to be to vigerous.
The process will proceed faster if you use warm (50deg) water. If you are using a tank heater, switch it off while plating. After about an hour the process should be complete and have a rich head on the elecrolyte.
Remove the item being cleaned and rinse. If it requires more cleaning put it back in the tank. If you decant the electrolyte you can use it again.
Items like this bracket \ catch can now be disassembled ready for plating. Even if originally seized, they should now come apart easily.
This catch has a chrome handle and a steel bracket. The chrome bracket is in reasonable shape, but could be plated with replica chrome after dechroming. The steel bracket and the bolt and washe will be zinc plated
Although the parts have just come out of the cleaning tank, degrease and acid pickle before plating. Suspend the parts from the  bus bar and plate for 25 minutes at 0.1 amp per square inch.
The parts will come out of the tank with a bright shine. If left untreated these will dull after a few weeks. The zinc kits contain clear and yellow passivate dips to prevent the dulling.
Assembled, almost as good as new and ready for another 50 years of service.
