I've had a few piercings in my day, and some of them are different depending on the placement, but here is the rules of cleaning that I've always followed and never had a problem.
Basically don't touch it, at all. Don't twirl it, don't push it back and forth, don't pick at any crusties that form. Don't use neosporin or any kind of ointment, the puncture wound can't breath, ointments are for surface abrasions, not punctures. Use a seasalt and warm water mixture. Soak it for a while and rinse, get any crust off by soaking and rinsing not by picking or turning. If you feel the need to move it, just move it once while cleaning it. Other than cleaning with sea salt, keep those fingers off it, and try not to get anything in or around the piercing and you should be fine.
