Quoted from YeOldPinPlayer:Vinegar is a mild acid. Suitable for neutralizing alkaline. https://pinside.com/pinball/forum/topic/terrybs-guide-to-repairing-alkaline-battery-damage
Actually, vinegar it's not acidic enough to do much of anything in this case.
Zep toilet bowl cleaner is a better option, which is more acidic and will actually react with and remove the alkalaine. It's also a viscous material, so it won't get all over the board.
Quoted from YeOldPinPlayer:I disagree. Acids and bases will always neutralize one another. That's the way the chemistry works. The stronger your acid the more abundant the hydronium ions. The stronger the base the more abundant the hydroxide ions.
Vinegar (pH about 3) has fewer available hydronium ions than Zep (pH about 1) so it will take more vinegar to neutralize the same amount of alkaline. It will still get the job done from a chemistry standpoint.
terryb goes into other advantages/disadvantages in his guide.
I need to record a video the next time I do a repair. The difference is night and day between using zep and using vinegar.
Two passes of zep does what vinegar simply can't, even with a dozen passes.
You can watch as the zep removes all of the alkaline and corrosion from the surface of the board and metal. With vinegar, it's barely touched.
After treatment, desoldering is a breeze, and I'm not getting all that nasty material all over my soldering/desoldering equipment. Then it's sanding time, another round of treatment, cleaning, and then ready for re-population.
