Question: can you use kosher salt to clean nipple piercings?
Answer: (Moisture is essential for healing.) Do not use table salt, kosher salt, Epsom salts, or iodized sea salts. Non-iodized fine-grain sea salt is best for avoiding additives, as well as its ability to dissolve into a solution. Do not make the solution too salty, as that can be irritating to the piercing and to the skin.
