Default Re: Zinc plate and passivate? Restoration.

Never had any problems, either on the High Street or ebay.

Used some citric yesterday to clean up a small mild steel bracket which was rusty in some places and covered with zinc plate in others. Cooked it up to about 50°C, and after about an hour, both the rust and the zinc were gone leaving a very a really nice surface to paint with primer.
