Whether it's because of pregnancy or distaste of your piercing, there are many reasons to take out your navel piercing. The key is using a gentle hand to be sure not to rip the already sensitive piercing site.
Clean the piercing area
Gently wash the area with mild antibacterial soap. This reduces the chances of any infection of the piercing site should a rupture of the skin occur.
Slowly remove the piercing
Unscrew the balls on either end of your piercing, and place them aside. With clean hands, gently pull up on the piercing from the piercing site. This is a painful process as the skin tightly heals around the wound in various degrees depending on the age of the piercing. Take as much time as you need in order to reduce your discomfort during this process.
Soak in a salt bath
Just as a sea salt soak helped in healing your piercing, it also helps when the piercing is out. Using a ratio of 1/4 teaspoon salt to 1 cup water, soak in a bath up to two times per day to reduce irritation of the site. This step is necessary depending on the age of the piercing and irritation of the site upon removal.
