What type of soap should you use to clean belly piercings?

Answer 1

There are several ways to answer this question...

1) there are specific products that seem to be sold/recommended at most piercing locations. For specifics, please see the first link under "sources" (at the bottom)

2) there are some generic recommendations - which are on the "Association of Professional Piercers" website...and which are copied on most piercing store websites. I've copied these into this answer (just below) and put the source (at the bottom).

Use one or both of the following solutions for healing piercings: * Packaged sterile saline solution with noadditives (read the label), or a non-iodized sea salt mixture: Dissolve 1/4 teaspoon of non-iodized (iodine-free) sea salt into one cup (8ox) of warm distilled or bottled water. A stronger mixture is not better; a saline solution that is too strong can irritate the piercing. * A mild, fragrance-free liquid soap-preferably anti-microbial or germicidal. * WASH your hands thoroughly prior to cleaning or touching your piercing for any reason. * SALINE soak for five to ten minutes once or more per day. Invert a cup of warm saline solution over the area to form a vacuum. For certain piercings it may be easier to apply using clean gauze or paper towels saturated with saline solution. A brief rinse afterward will remove any residue. * SOAP no more than once or twice a day. While showering, lather up a pearl size drop of the soap to clean the jewelry and the piercing. Leave the cleanser on the piercing no more than thirty seconds, then rinse thoroughly to remove all traces of the soap from the piercing. It is not necessary to rotate the jewelry through the piercing. * DRY by gently patting with clean, disposable paper products. Cloth towels can harbor bacteria and snag on jewelry, causing injury.
