Not the best solution in this case, but coincidentally one that I used to revive a handheld multimeter last year: A pencil eraser will polish up old copper contacts very nicely. It's the gentlest way I've found to cut through the oxide layer and a nice hack to have for cleaning up delicate contacts in old electronics.
- dtgriscom 5y agoA classic trick. Works, too.
- colinng 5y agoAlso for bad contacts in old devices (or for the removable battery in my eBike), MG Chemicals conductive grease works wonders. And you can keep everything “original”. For zebra conductors I would try applying a very thin layer of the grease to the copper pads (after cleaning them with a pencil eraser) to assure only conduction along the desired path.
