The baking soda fix myth should be killed :)
Baking soda is a base. The electrolyte in NiCad batteries is alkaline, i.e. a base.
I can't see how a base would remove a base, other than diluting it perhaps if the concentration is lower, but I don't think that's the point.
I guess it stems from the assumption that all battery electrolyte is acidic, as in car batteries.
It is probably the _cleaning_up_after_ putting baking soda on that helps, not the soda itself.
Diluted vinegar (being acidic) would probably be better to neutralize the mess after a leaking NiCad battery if it is "fresh", but I think the key is to wash the electrolyte leftovers off. Water would probably work fine, but isopropyl alcohol might be preferable.
In particular, if neutralizing with an acid, you definitely want to wash it afterwards, or the acid will attack what the electrolyte missed :)
If it has corroded metal already, you should remove that stuff mechanically.
That's my firm conviction at least :)

I had a NiCd leak on my Trident MKII; the corrosion also caused chips to have bad contacts with their sockets. Check.
Also, you have to stabilize the corrosion. Have been told cleaning the boards with baking soda is efficient; I've done this, and so far so good. Wash thoroughly and dry with hair dryer.
