  • How to clean up battery corrosion...

    Anyone have any good suggestions? I had a new set of AA batteries go south and leak inside a remote control. Most of the leakage was on to the plastic parts and I got that all off, but there was a little on the battery contacts too. I cleaned them off with Caig Deoxit. I've also used Coke on car battery terminals, but never on electronics. Baking soda might also neutralize it...

    I'm just looking for THE best method / suggestion, and appreciate everyone's advice.

    Make a paste with baking soda.
    Nice and gooey so it sticks.
    Leave it on a little while, then wipe it off with a damp paper towel.
    Should work in tight spots just fine.

        I've used a warm water and vinegar concoction with leaking batteries on old computers. Go 50-50 with water to vinegar, dab it on, neutralise that acid. I've used baking soda on bigger messes but preer the vinegar method for small delicate clean-up jobs.

            Baking soda isn't going to neutralize it becaus alkaline batteries aren't acidic. That's why they're called alkaline batteries.

            Coke/Pepsi/Vinegar should work since they're acidic. Acid neutralizes base.

            I usually just clean it up as well as possible with a Q-tip/paper towels, and let it be, especially on something like a TV remote. The crust on the contacts is still conductive, and it isn't like it's going to make your next battery pop.

                What I didn't mention is that it's a music remote (a Frontier Design Tranzport - one of the coolest products ever - seriously! ), so technically it's only semi-OT.

                    You used carbon batteries? They control remote warmer.

                      I would use soda and a hard bristle.

                        Cramoline R5, which they discontinued because of the fluorocarbons, so the new stuff that used to be Cramoline is: Caig R5

                        That IS the stuff to use.

                        Trust me on this Phil

                            This is how Internet rumours get started.I sure didn't read Alkaline in Phil's post.Did anyone else??

                              I assumed alkaline since he just said AA batteries without specifying a type, and alkaline is the most common.

                              There are people in this thread suggesting both acidic and basic substances because it neutralizes the leakage from the batteries. Assuming that actually matters, it's got to be one or the other. If it's an alkaline battery it's the acidic stuff.

                              http://en.wikipedia.org/wiki/Alkaline_battery

                              Alkaline batteries leak KOH, a strong base.
