Cleaning your piercing is important, both to prevent and treat an infection. Experts recommend cleaning a piercing no more than twice each day. Use a saltwater mixture (1/2 tsp sea salt per 1 cup of water) to help remove any dried healing secretions. Follow with a mild antibacterial soap and water cleansing.
In respect to this, is it okay for your belly button piercing to pus?
It’s normal for a white or yellow-colored fluid (not pus) to ooze from your new piercing. This may form a crust that can itch or feel tight. Try not to pick at it, since that will cause the area to bleed. This crust will come off on its own as your piercing heals.
