Mix a pinch of iodine-free sea salt, about 1/8 tsp., into a clean coffee mug filled with boiling water. Allow the water to cool until it is comfortably warm.
Soak your hand in the warm salt water for 10 minutes. Repeat the process twice a day, using a clean coffee mug each time. Pour the water into a bowl if it is easier to soak your hand that way.
Wash your hands with antimicrobial soap immediately after soaking and anytime they get dirty. Lather your hands well with a pea-sized amount of soap and rinse them with warm water.
Dry your hands with a fresh paper towel after every wash.
Repeat the salt water soaks for at least eight weeks. Continue to wash your hands with antimicrobial soap for the life of the piercing.
