Clean twice a day. Over cleaning may irritate the wound slowing healing. Avoid contact with body fluids. The most frequent cause of infection is touching the piercing with unwashed hands, followed by contact with unclean hair, clothing, bedding, etc. Avoid used washcloths and sponges when cleaning unhealed piercings.
Tight clothing can contribute to the migration or rejection of piercings.
Healing times vary greatly from one type to another, and are generally longer than you expect. Some times can be shortened or lengthened by the choice of jewelry.
