I just remembered that we've got this oil at home: Q10 Penetrating Oil, but it doesn't say what it's made of so I'm not sure whether it's safe to experiment with.

Good to know if I ever need it, but that headlamp isn't worth the bother as I replaced it a long time ago. I was just curious to see if I could get it to work without any expense.

| +1 on the lithium grease suggestion, it works. |

| If the plating is gone you can coat the contacts with a lithium grease (white grease). It will prevent further corrosion but still allows the battery to contact and provide power. It's also really good for car door springs that squeak. I use it on my car batteries to prevent the corrosive build up. (Electronics technician for 40+ years) |

A few years ago we bought a couple of small headlamps to use during our frequent load shedding (planned power cuts) and the batteries leaked in one of those too. As it was a cheap item I simply replaced it at the time, but I still have the damaged one, so I tried vinegar on that too. No luck (so far). Perhaps it only works if the damage is caught early. Or maybe I need to try harder.

I hope I'm a bit smarter now too. The first thing I did was remove the batteries from my ring flash. Better safe than sorry.

| I've saved several pieces of equipment over the years with lemon juice, a piece of paper towel, and a unfolded paper clip. The lemon juice does a pretty good job without a lot of pressure. I'm a bit smarter now and try to remember to remove batteries from items that are infrequently used (i.e. GPS handheld unit, Walkie-Talkies, etc.). |

| Thanks ... "Q-tip" is the most common brand of cotton swab (our generic term) in the USA ... |

Thanks.

Where there was enough space to reach I used an old toothbrush. For the rest I used a cotton bud (apparently known as a Q-tip in other countries).

The video uses vinegar. If lemon juice works, I guess vinegar will too, and it's less sticky.
I saw another video using Coca Cola. I'd be scared to try that. |
Sounds like they just want an acidic solution. Cola would work but probably leave a sugary residue, however it's supposed to be great for cleaning oil-stained driveways ... :-)
Let us know if it works -- I have a similar situation myself. |
Sorry for the slow response. I only found time to clean my flash this morning and the good news is it's working.

vinegar is a good cleaning option. I'd be comfortable trying that.
Dry scrape as much as you can first, before trying the liquid.

I'd try cola on something that can be washed afterwards, but not on a flash.
If nobody suggests anything else, I'll try vinegar tomorrow and see what happens. I often use vinegar for cleaning, but didn't think of it for my flash.
I'll let you know what happens.

The batteries leaked inside my Canon 270EX speedlight. It's old and cheap but I'd still like to save it if possible.
Is this method safe?
