A. Use a very brief electrocleaning step for zinc. Longer durations in electrocleaning solution will open pores (porosity), causing blistering during subsequent plating steps.

B. When copper-plating zinc, the copper deposit must be thick enough to prevent gassing during the acid dip step. If gassing does occur, rinse well and plate with more copper. Then repeat acid dip and following steps.

* Copper over steel provides durability and acts as a barrier against rusting; however, silver will plate directly onto steel if desired for a particular application.

** HCI dip is a 20% hydrochloric acid solution.
