Izzy is essentially right. Make sure you clean it well, all the foreign bodies out, etc. Picking them directly out instead of scrubbing hurts less. Most pain receptors respond to shearing forces (just an FYI for the "random facts" folks)

Non-stick like Telfa can still stick a bit. Vaseline gauze probably would work but isn't the best, there also saline-impregnated gauze.

Either way, keeping it moist helps heal faster and scar less (which ultimately means better cosmetics and a bit improved tensile strength). Vaseline, Neosporin, or one of those variations every 6-8 hours works.
