Can loose zincs lodged in heat exchanger heads be safely chemically dissolved?

I have numerous "broken off" zincs loosely lodged in their respective heat exchanger heads on my Yanmar engines (four on each engine). Does anyone have any experience with safely chemically dissolving them without corroding the exchanger's metal components? Removing and reinstalling the heads to clear the zincs will be an absolute nightmare due to lack of physical access (very poor design layout).
Any feedback would be appreciated, but unfortunately, I think I already know the answer to my inquiry... but just incase, thanks anyway,
