Before piercing, it is necessary to thoroughly clean in and around the belly button to remove any bacteria from the surface of the skin. It's best to use a disinfecting skincare gel especially designed for piercings (such as Bactine) or rubbing alcohol.  Generously apply the disinfectant or rubbing alcohol to a cotton ball and wipe thoroughly around the area to be pierced. Wait for the area to dry completely before proceeding. If you...
