    Best way to clean a battery leak?

    I had my batteries (Duracell) leak inside my Cateye flasher.

    Now it has a white gunk mucking up the works.

    An real obvious solutions (without destroying the electronics)

    If I recall correctly alkaline cells contain potassium hydroxide and the traditional way to deal with it has been to use plenty of fresh water and maybe an old toothbrush and then dry thoroughly - I could be wrong though....

    You could try contacting Duracell:

    If you're not completely satisfied with a DURACELL Product,

    All DURACELL Batteries are guaranteed against defects in material and workmanship. Should any device be damaged by these batteries due to such defect, Duracell will repair or replace it (at Duracell's option) if it is sent with the batteries, postage prepaid to:

    That was wonderful.
    Sadly, I've already disposed of the batteries
    And my flasher is dead

    *grumbles*

    If you haven't thrown it out yet, try Corrosion X. I can't tell you how many electronic things I've brought back to life with this stuff. GPS's that leaked saltwater, Lights with battery acid, Even a mp3 player that got totally submerged in salt water (that one took awhile though). Stuff works miracles. It won't mess up electronics or contacts, just soak, let sit, shake out and let dry, repeat if necessary.

    Thanks for answering my question as well.

    A few days I rode through a storm that was so fierce that I was in low gear going down-hill and for the first time in my life I had to stop and let a storm pass.

    But tonight when returning from the fireworks show, I noticed that my light was out. By luck, I had brought along a fresh set of batteries. When I opened the Cateye Opticube up, I noticed that it was unusually easy to open and that there was a lot of alkaline residue in the battery compartment. So I guess that it got wet inside and shorted out.

    I tried to clean it out in the dark with a key and put in the fresh batteries. The light was very weak, but a little stronger. I cancelled my plans to ride the very dark but beautiful bike path along the river and took a longer route through the better-lit city streets.

    I will try to find some Corrosion X. That, or perhaps get some contact cleaner from an electronics store. I brought a dead TV back to life with that once.

    Update, I just swabbed the contacts with vinegar, a mild acid, using a Q tip and that has helped a lot already.

    I always use multiple headlights and taillights, just in case one quits for some reason.
