how do I clean the charging port on my iphone6

Something non-conductive like a wooden toothpick.

A bright light, decent magnifier and and something to pry out the pocket lint are generally sufficient. Any thing more involved than that should be handled by Apple or an authorized service center.

As a person who actually fixes iPhones every day, It could equally likely be pocket lint, a broken charge port, or a Tristar chip problem. I know for sure that the most efficient thing to do would be to take it to someone who could diagnose all three possibilities on the spot.

Despite your desire to dismantle the OP's iPhone (for a small fee, of course), they are seeking advice to clean the port.

Based on advice given in another thread, I broke a q-tip in half, and used the broken end. Worked beautifully.

Yes, I see that my advice to start by using a Q-tip with 99% alcohol was summarily deleted like so many other pieces of sound advice I've given today on this forum.

But that's also not what the person to whom you're replying did. They did not use alcohol. They didn't even use the cotton end. They cleaned out the pocket lint with the stick of a cotton swab.

Good suggestion. It's a bit thicker than a toothpick but much less likely to splinter.
