Do not over-clean your piercing. … Salt water and/or saline solutions should be used to irrigate your piercing, but it is the action of flushing out the wound that helps healing, not the saline itself. Likewise, soap should just be treated like soap; lather around your piercing and then rinse thoroughly.
In this regard, why salt water is bad for piercings?
First of all, when mixing sea salt with water, you will almost never achieve the correct concentration; too much salt will dry out the tissue and result in complications with healing. Not enough salt, and it will not clean your piercing effectively.
