I have a bunch of batteries including USB passthroughs that just dont stay lit long enough to get a good long led blinking drag off of. If you see your battery led turn off before the 3-5 second drag is over and you cant get the led to blink then your battery to is gummed up.
I had nothing to loose because the battery and the USB pass through was non functioning anyway, so I used my wifes high pressure steamer.

This thing shoots out high pressure steam in a pin point stream. I shot my full charged but gummed up switch battery with it for about 20 seconds. Let it drain and dry then tried it out and the battery was like brand new.
So I did the same thing on my USB pass through that was not working at all, i mean no led or nothing, and the switch got free and clean and is now working brand new condition.
So then I steamed the sink and stuff around the house. Any way, just figured Id share this with everyone.
