First of all you need to have some warm water in glass. Now take an ear bud and dip into the warm water. Now apply some soap over it. You can use the hand soap also for this purpose. Insert the bud in your nostril and then rub it around the pierced skin. Remove all kinds of particles accumulated at this portion. Now clean the other nostril as well. Now hold your pierce ring with your two fingers and give it shake. This shall remove all solid pieces from the area. Otherwise these may go down in your mouth. Don't use any kind of alcohol to clean the pierced nose. Always use gentle soaps to clean your nose. Otherwise hard chemicals shall dry up your nose. That's it.
