Greening in my galaxy buds terminal

[lelei1]

Hi, i recently realised that the terminals in my galaxy buds are starting to turn green like the terminals in a leaking battery. How concerned should i be for the safety of my ears and myself for that matter? 

Greening on one of the terminals!

Hi @lelei1
It could be a reaction to oils in your skin, similar to how some people can't wear silver jewellery as it turns green.

You could try using a cotton bud dipped into isopropyl alcohol to clean it off, or a pencil eraser.

Do not use electronic contact cleaner as they can damage some types of plastics.
