All you need is q-tips and nail polish remover. Pull enough cotton off the tip of the q-tip so the swab can fit into your audio jack, should fit snug and you just twist it around a bit then dip the other side of the q-tip into the nail polish remover and repeat, I did this twice and the audio jack on my Moto X is working perfectly. I was about to go mental. So you are welcome. :)
