HI,

I have a remote for a CD player that has not been used for awhile. I was horrified to open up its battery compartment where the AA Duracell batteries in it had leaked junk over the compartment.

These is a whitish crystalline crud over the terminals and it looks as though some clear liquid goo has flowed out as well.

I don't know if this has ruined the remote, but I wonder what I ought to use to clean this junk off?

Thanks for any advice,

George Roland

I use isopropyl alcohol and a Q-Tip.

Happy listening,

Jim

Duracell claims they will repair/replace the remote:
If not completely satisfied with your Duracell battery product, call 1-800-551-2355 (9:00AM - 5:00PM EST). Duracell guarantees its batteries against defects in materials and workmanship. Should any device be damaged due to a battery defect, we will repair or replace it at our option. Leaking battery and damaged device must be provided as proof of claim. Duracell may deny claims of damage caused by misuse or modification of the batteries or device.

 

+1. Duracell replaced two flashlights for me. nt, posted on December 2, 2016 at 16:37:36

I make a thick paste from baking soda and water and apply it using an old toothbrush. Then I follow up with plain white vinegar to clean up the mess.

No different than cleaning up automotive battery terminals that have been neglected and allowed to create telltale "popcorn", except that on autos I use old wire brushes instead of toothbrushes.

the battery gunk is like a hydroxide and vinegar is acid. the whole idea is first to mechanically clean off all you can and then follow up with a Q-TIP wetted with vinegar which will NEUTRALIZE the white gunk.

keep at it until is all gone and you can finish up with another qtip wet with water.

Since I bought my first car while in HS I was told the best way to clean battery terminals was with a mixture of baking soda and water, applied with any clean, short-bristled brush. And so I've continued that procedure with any household or audio applications and it has worked just fine. However I don't mix a "thick paste", mine is pretty watery. I just dump a full teaspoon into maybe 4 oz water and stir it up.
