Sea salt soaks serve as a quick, cheap home remedy that is effective for the after-care of a piercing, both body piercings and oral piercings. Sea salt soaks help the piercing to heal, reduce swelling and redness, and clean the area. To make a sea salt solution you first need a non-iodzied sea salt (do not use any other types of salt, eg. table salt or epson salt). Mix 1/4 teaspoon of sea salt to 8oz of warm water. If you are able, invert the cup so the liquid inside completely submerges the pierced area. If you are unable to do this, use a Q-tip or cotton ball to gently apply the solution to the piercing. Keep the solution on the piercing until it cools---at least five minutes.
There are premixed saline solutions which you can also use on a piercing.
