If you drill out the center of the old zinc ti say 1/4", you can use an
easy out to unscrew it from the brass plug. I clean the threads with a
small  sort of bottle brush with metal tines  I  put it in an electric
drill and clean out the threads that way.  They come out shiney and clean.
No acid needed. I do put a dab of Koppershield or silicon grease on the
threads when I assemble it.  That seems to make the  zinc unscrew from the
brass more easily.
