The outer opening of the piercing is best treated using liquid antibacterial soap or Bactine. If the liquid soap is too harsh it may be diluted 50/50 with water (avoid perfumed products). Apply liberally with a cotton swab or Q-tip.
Besides, what should I clean my septum piercing with?
If you just got a septum piercing, the main cleaning method involves sea salt soaks three times a day. You should also strive to keep the piercing clean by avoiding activities like swimming and only touching the piercing with clean hands. Even with excellent aftercare, infections do happen.
