If you don’t clean them at least once (preferably twice or more) per day, you run the risk of infection. A piercing is an open wound and for the first few weeks, you might notice some ooze coming out of it.
Regarding this, what happens if I don’t clean my septum piercing?
Most septum piercings will heal up without a problem if you keep them clean. Unfortunately, however, infections do sometimes happen. The following are signs your piercing has become infected: Yellow or green discharge.
Beside above, do you have to clean piercings after they heal?
If your piercing is still healing you should never ever remove jewelry. But even once healed, you don’t need to remove your jewelry to clean the area. You can simple clean around and under the jewelry while it is still in. This is often the case with healing piercings, but especially healed piercings.
