Oatmeal bath/wash in tepid to warm water with a tablespoon of bleach. It took the redness and itch out of the rash for my daughter. Then A&D ointment on open areas and lanolin on closed areas, unless she was on a prescription at the time. Also, less fried and processed foods during the flare. Increasing water and fiber intake seemed to help too, well it helped her not be as miserable.
