Use either, sterile saline (for wounds with NO additives), H2ocean spray, or a properly mixed sea salt and water solution(instruction near bottom).
Use a mild liquid soap with no fragrance, that's antibacterial, anti-microbial or germicidal. Do NOT use any other products on your piercing, especially most first aid products like alcohol, hydrogen peroxide, Neosporin or any other cream/ointment.
Wash your hands before cleaning or touching your piercing, and NEVER remove your jewellery during the healing process. Avoid swimming or submerging the area until fully healed.
Once or twice a day at most, use a small dot of soap and farm a lather in your hands, use your fingertips to gently clean the piercing. Do not leave the soap on for longer that 20-30 seconds. Rinse thoroughly and pat dry with a clean paper towel. This is easier done in the shower.
Use cleansing solution to soak the piercing once to twice a day for 5-10 minutes. You can do this either by soaking a cotton ball, piece of gauze or paper towel and holding it on the piercing firmly or by filling a small cup with the solution and inverting it over the piercing if possible.
If necessary you can use your solution or warm water on q-tips throughout the day to remove any secretion/plasma from around the piercing. Do this gently. Dried secretion can be very damaging if the piercing is hit or rubbed while present.
Rinse mouth with alcohol free 4-5 times daily for 20 seconds, mainly after meals and before bed. Do NOT over use, rinsing too often or with too strong of a mouthwash can cause irritation can or soreness of your mouth and piercing.
For swelling use ice or an over the counter anti-inflammatory like ibuprofen.
Sea Salt Mixture
Use non-iodized (iodine free) natural sea salt only, dissolve 1/4 teaspoon into 8oz of warm distilled or bottled water and shake well. Making or using a stronger mixture will only irritate and dry out the piercing.
