Battery terminals

[Csail]

The contacts in night vision goggles have got a kind of copper deposit on them.Pain to get to where the aa batteries go but is there anything i could put on a cotton bud to clean it?

Gold plating?

The contacts in night vision goggles have got a kind of copper deposit on them.

Sometimes battery contacts are gold-plated. Is this what you mean?

To clean them try a little bit of metal polish, e.g. Brasso, on a cotton bud. Hope this helps. Bill

Not so much a help in cleaning, but afterwords to prevent re-occurrence I would suggest putting on a smear of Vaseline. I tend to apply this to electrical contacts of all new gear and find it makes a big difference,.

Funnily enough i just used PTFE spray....guess that does the same?

I've used a graphite pencil to successfully clean and restore contacts, just scribble over the corroded bits.

you have to neutralise the acid or alkali which is causing the corrosion. It's just like anodes on a boat - the weakest bits get eaten away.

A bit of distilled water on a cotton bud, followed by a bit of glasspaper to remove all corrosion products, then vaseline.

PTFE is normally regarded as an isolating medium, and will just allow corrosion to go on under a layer of the gunk.

Best done properly: good NVG stuff is valuable. Only use the best batteries.

ink rubber

an ink rubber perhaps you can get them that look like a pencil . .. a bit more abrasive than a pencil rubber but not much
