Black spot on charger cable?

[Brandon2000]

As anyone experienced this? I seem to get it on every single lighting cable I ever had

I think it’s something to do with the phone as I have just bought an official apple cable and the gold parts have turned black on both sides i have only used the charger for a day and it now doesn’t work at all.

Happens on my official cables too. I just wipe it off, I assume it is dirt or dust build up.

I have that problem but they definitely don’t clean up. I’ve even used a razor blade to gently scrape it off but nothing seems to work.

Hi, normally also we should put the cable with the USB sign side up. It's design is such and it fits perfect. Always keep the USB icon side up.

There is no USB logo on the lightning adapter end of the cord. That Logo doesn’t appear on USB-C adapter ends either. It only appears on the USB adapter ends… But you would never put that into the iPhone.
