Leaky Batteries (was: Lisa 2/5 Startup Problems)

I have seen a number of cases where the battery leaked and the area was cleaned up without neutralizing. Looks fine until a couple of years later when things start getting flaky and finally die. A close look will usually show the area where there USED to be traces! I usually use Muriatic Acid as it does a good job of neutralizing without damaging the circuitry or the solder joints. BTW, I only use a few drops straight muriatic acid (= 33% HCl) and after all the foaming stops, rinse it well with water trying to only get water on the affected area (makes drying easier). I use tap water but DI or distilled water is best since it won't leave a residue when it evaporates. A thorough drying follows.
