    Default Neutralizing battery acid on board

    Just got a brand new Tandy Cordless Mouse I wamted to start using but the barrel battery inside leaked pretty badly. I think I can save it but is there any good way to neutralize the acid that's already soaked into the board? I've never tried before because all the motherboards I had with battery damage were too far gone to be saved

    Ditto... there's no acid coming from those batteries. It's a base so you need an acid to neutralize it.

    A spoonful of baking soda made into a 'paste' and scrubbed with an old toothbrush using distilled water from Mama's iron.

    Not 'baking power' or baking powder, or even baking soda which is what you really want to use to neutralize an acid. They're all basic. These batteries leak a basic compound and you need an acid to neutralize a base.

    Yep. White vinegar to neutralize the caustic bases and scrub with a q-tip or toothbrush. Then follow with some isopropanol to clean off the vinegar

    Well, I wanted to start the year off right with a nice snafu. Mainly, I wanted to see if you were on your toes this morning.

    Ok, I didn't realize the leakage was alkaline, guess I'll get some vinegar on it asap. Kind of weird everyone refers to it as "battery acid" even when it's not

    Lead acid batteries are very common (motor vehicles, security systems, battery backups, etc.) and they do in fact contain acid. People just started referring to all battery fluids as "acid" because of that.
