Does anyone know what the trade uses to remove chrome before replating? I have some bronze boat fittings which have been poorly plated some time and I want to revert to the bronze.

I would guess the reverse of plating ie: the plated part becomes the anode in the system (positively charged I think), whether the cathode then needs to be the the plated material in some form or other is beyond my limited knowledge. Chrome is usually deposited over nickel so could be an added complication.

I seem to recall the platers avoided removing chrome as it contaminated their tanks.
If you think of having them de-chromed, you may want to consider that in triple plating the first layer is copper, then the nickel/chrome. Which would imply that reversing the plating with bronze may corrode your fittings.

Hi Malcolm
Any chrome replater will be able to remove old chrome, they use various chemicals to strip it depending on the base metal and the under layers, it is not really a DIY job unless you wish to invest in a lot of kit.

Hi malcom - chromiun plate is removed by immersion in sulphuric acid , it always results in pitting and the need for re-polishing.
