Question How to clean Wireless Earphone connector pin

[mzsheikh]

Hi,
My right earbud is not charging, due to maybe the corrosion/carbon. See below, the top right connector. How can I clean it and to make the charging work again or is it seems to be damaged? Thanks

pencil eraser. works wonders with a coin.

I put the pencil in a drill and spin the eraser, remove any remnants afterwards.

Link seems broken but any kind of scraper. Some kind of wire brush as long as it doesn't scratch the surroundings.

You need to upload the image to an external image host like imgur. Then post the link here.

I use actual contact cleaner on my audio connections. Obviously that won't fix a damaged part.
