    Tried posting on and for some reason it's not letting me. This site's probably more useful anyway though :-D

    So far I've had 100% of lightning connector devices fail (never had an issue with the dock connector nor USB).

    I bought a Smart Battery Case with my iPhone 6s last year, hoping that by having the phone permanently plugged in to the case, it would protect the lightning connection...

    Off and on I've had issues with it, but they've been solved by rebooting and connecting/disconnecting the case and phone until they both work.

    Well, it's getting worse now, and the physical connector in the case is turning partially green (despite being physically connected to the phone 100% of the time).

    Wondering if there's a way to clean it safely or fix it period. Right now my case charges fine if it's plugged in to power by itself (with the phone removed), but the phone's connection-seeing the case, connecting cleanly to my PC, charging from the case, is all hit and miss, even after multiple reboots and re-connections.

    I've tried cleaning lightning connectors in the past, and while I've gotten them to physically look okay, they NEVER work again. (Had many cables fail in the past too as far as that goes.)

    Really wish Apple would switch to USB...

    Not the greatest picture of it, but you can sort of see what the physical connector looks like. (Which may or may not even have anything to do with the issue.

    Blow out with one of those air cans used for keyboards etc.
    And if Apple switched to USB it would be USB-C which physically looks just the same

    Try dabbing it with a Q-tip dipped in alcohol. That may help clean it.

    I would start with 90% or higher Isopropyl alcohol. However to remove corrosion something like lemon juice or vinegar works best.

    Yep, @dreadnort is right - pencil eraser - the white stick ones that go into the dedicated pencil eraser holders work best for that. Sometimes a T-Shirt pinch and wipe works as well. I usually ignore it tho and haven't had a problem with one of my cables looking like that for over a year now.

    That is how I would do it as well.

    Stop getting it wet and they'll stop corroding. That's a connector that's been electrolyzing.
