Removing Chromate Conversion Coating Without Damaging Cadmium Plating
What are the easiest methods for removing a Type II conversion coating from cadmium plated steel parts without damaging the cad plate?

A quick and easy method to strip chromate coatings is to simply immerse the parts in an alkaline cleaner. This will not damage the cadmium plating. You would then of course lose any subsequent resistance to oxidation of the cadmium.

If you boil it in distilled water for 15 minutes, you will have removed all of the visible color and most of the chromate. Anything stronger will attack the cad at a speed proportional to the concentration and temperature.
