I searched for "alkaline battery acid" and got no results.

I had one leak on my work bench in a hot garage .....
Can someone refresh my memory for what to use to remove it ?
As I seem to recall ... the answer is not Baking Soda/water paste.
Even though that does work on keaky Auto wet cells.

(It was an Energizer Alkaline AA ,... somewhat drained)

Please advise ...... and Thanks

It's not acid; hint: "alkaline battery". The electrolyte is potassium hydroxide solution in water. Use an acidic material such as vinegar to neutralize spills.

Last time I used some lime drops (acidic material) and scraped off the leak build up. The alkaline took off the anodizing finish though.

Hi all, I'm new here.
Try to get hold of a small ultrasonic cleaning bath and use as the cleaning/neutralizing fluid a very diluted solution of acetic acid, such as Household vinegar diluted 1+7 with distiled or DEMI water. Renew the liquid a few times.
Once the batteries come out (It can take a few hours) and most of the leakage has been dissolved, replace the acid solution with distiled or DEMI water. Renew a few times.
Rince a few times with ethyl alcohol or isopropyl alcohol (dont use the ultrasonic for that: fire hazard) and let dry overnight. I use an old bacteriological incubator, set at 50°C = 122°F for that.
That's all. I recently cleanded up an old Maglite 3D, containing Duracell batteries that had been fused with the inner surface of the flashlight. I managed to remove the first cell using... well... brute force. I decided to try it the way I described above. It worked like a charm.
