My phone is not wanting to charge. It will stop/start with a little wiggle of the cable. I had it with an old phone that there was lint/dirt in the 30 pin adapter. The lightning adapter is harder to see. Is there a good way to clean it out without damaging anything? Is it pretty durable inside that I can use a toothpick or something to dig around with no worries? Any other ideas if my phone isn't charging unless I wiggle the cable? If I hold the cable with pressure forward it charges, otherwise it's on/off and sometimes I wake up after charging overnight to a still dead battery.
