Battery Corrosion

[RyMoeller]

Hi, I'm looking for some tips on how to best deal with removing battery corrosion from a plate.  

The plate below is from my father's Accutron 218.  The battery failed and leaked at some point leaving a salt-like deposit that seems to be insoluble.  I've tried an acid bath (vinegar), alkali bath (sodium bicarbonate), and good old fashioned elbow grease to no avail.  At this point I'm thinking of just letting it be since it seems the plating is flaking off beneath and the corrosion shouldn't impact the function of the movement.

If anyone knows about a magic bullet though I'd sure like to hear.

You need to neutralise the acid else it will continue to eat away.

Plenty cheap ways of doing it.
Have a quick search on this forum as I remember at least a couple of threads.

yes,  neutrolize "after acid".  i think you will find it has been etched down to basic metal (aluminum ?)
