Headphone audio Jack works when it wants

My i pod nano 7th gen audio jack only works when i put some Isopropyl Alcohol on the tip of my headphone's plug then stops working after couple minutes (my guess is that the Isopropyl alcohol got dried out).I'm out of ideas for this alcoholic jack.I tried cleaning it with a q-tip with some alcohol but the problem persisted after it was thankful for the alcohol.I really like my music but this is frustrating since i got to do it every time, any suggestions to help resolve this problem?
