   I got an old AM-FM pocket transistor radio which looked good and clean   
   till I opened the battery compartment. Very corroded carbon zinc   
   batteries were in it. After removing them, I cleaned off as much of the   
   corrosion as possible by scraping with a plastic stick, and scrubbing   
   with q-tips and rubbing alcohol. That got rid of most of it, and I was   
   surprised to find the battery clips are not badly damaged, but I had to   
   use a fingernail file (sandpaper strip) on the ends of the springs.   
      
   Better yet, the radio works perfectly.   
      
   But there is still a little of that battery corrosion still in there. In   
   all the years I've worked on electronics, I have never found a perfect   
   way to clean up leaked batteries. Is there some sort of spray or a   
   chemical that will dissolve or deactivate that crap?   
      
   Of course it has to be safe for the circuit board and components too. I   
   use the 91% isopropyl alcohol, so it evaporates quickly and leaves   
   little water residue behind. (Then leave it dry well before use).
