Your problem here is to disolve the zinc without disolving the part itself. Nitric acid is likely to disolve the base metal of the part because all nitrates are soluble and nitric acid is an oxidising agent as well as an acid. For stainless steel parts i would use a strong base because zinc is amphoteric and stainless steel is not. Amphoteric means it reacts with both acids and bases. Since bronze is also amphoteric, a different approach is needed. A weaker acid that will not disolve copper or tin oxide but will attack zinc might work. I would start with vinegar and then try oxalic acid and dilute hydrochloric and see what works.
