We are having 'economic' dificulties in removing metal sprayed zinc from a steel bridge deck (30 years old). Currently we have to resort to locally disc grinding after a single pass with a motorised shot blast unit.

Is there some 'benign' chemical cleaner or etchant that might reduce the adhesion properties to the steel substrate, thereby making removal easier.
Thank you,
Steve Fry
