The best soap I have found, which was recommended by a WOC Nurse, is Ivory Bar soap (has to be the basic old school bar soap). It has nothing extra and cleans oils away. I use it last after washing the rest of me, and only in the parastomal area; I use regular soap everywhere else. Ivory has no moisturizers or anything, so it leaves the rest of the skin dry if I use it, but for the skin around the stoma, it's perfect.
