OK so I went about a week ago to get my belly button pierced 3 times like in a triangle and one of the piercings is really red around it and I have been cleaning about 2 times a day with dial soap.. it started to look infected about 3 days ago.. I thought it would go away cause I have had my belly button pierced before but not 3 times at once.. should I soak it in salt? Or hydrogen peroxide? Neosporin? I have no idea.

The dial soap isn't helping. You don't have to soak in salt. I would disolve salt in warm water and just wash the area, but use the 3% peroxide, washing it over the area a few times in the morning and at night. Don't use neosporin.
