sticky residue inside charge port?
I tried charging my iPod earlier and it wouldn't charge unless it was held with the cord in a specific position. I looked at the port for the charger and there is a greenish sticky substance inside there... Any ideas on what it is or how I can get it out? I'm about to leave for vacation so there's no time to send it in or make an appointment for the Genius Bar. What would it be safe to try and clean the ports with that won't damage the pins inside or cause liquid damage? Already tried canned air, it didn't help since the stuff is sticky.
iPod touch, iOS 7
