I've found that some electrical equipment can be saved by washing its innards with ordinary white vinegar - the acetic acid makes the alkaline crud foam up and wash away. Follow up with clear water and let the device dry out thoroughly. Almost always works for me.

I'll give it a try, even though I already ordered the replacements!

Baking Soda will neutralize the battery residue and helps clean contacts. I have successfully used that for decades.

LOL!

Wouldn't Fixer be better for any broken photographic equipment?

How do you apply it?

FWIW, the leakage is an alkaline, like baking soda. A mild acid like vinegar neutralizes and dissolves it. Until recently, I thought it was acid leaking and used a baking soda paste to neutralize it. It sort of seemed to clean it (probably the abrasiveness of the baking soda). Vinegar works much faster though.

Baking soda is regularly used to neutralize battery and clean battery terminals on car batteries which is easy to do. What I do for electronics is to wet a small amount of baking soda and depending upon the compartment size you can use a cloth or q-tips to go over the contacts and wipe down the compartment area. You want to avoid getting liquid into areas that you might not be able to access. If you can disassemble some parts it might make it easier. Baking soda is very effective and it doesnít take much to neutralize the battery residue and will not harm any electronics. Once you are satisfied with the cleaning then follow up with a dampened cloth etc.

Personally, I would not use vinegar for this because it is a mild acid, actually ascetic acid, and as a liquid could seep onto electronics that you might not be able to reach and if left on it for a period it could possibly etch circuit boards. If you do use it then follow up with a dampened cloth with water or better yet distilled water.

By the way, you might consider using nitrile gloves if there is a battery leak that you are cleaning, but if you donít then put a small amount of baking soda in your hands to neutralize it.

Well, yes, it's essentially the same thing, but... The acetic acid concentration is much higher (generally used at 28% or so), while vinegar is generally in the 4%-5% range. I don't know what the higher concentration of acid would do to the (alkaline metal) parts. If what you've got is "glacial" acetic acid, that's almost full strength (98-99%). If it's already prepared, it's probably 28%. Either way, you could dilute it with water to make vinegar (though I wouldn't use it on a salad).

+1 to white vinegar and q-tips. Just make sure to wear gloves if you've got sensitive skin.

with ordinary white vinegar
vinegar works great!! as does some baking soda in water....vinegar is more convenient .....have revived a several battery compartments on old film cameras (even just getting the battery covers off) and a few flashes...……

I do try to remove every battery that is loaded in my light gear.....they get loaded on site outta the bag and unloaded going back in
