Hi Juliantheory: You are right. I have been rinsing my pouch for two years. Many times our output is very liquidy, so water should not hurt it. To me, if you do not rinse, things will build up around the stoma, and could make changing the flange not only messy, but painful. Moostly i use cold water, but on occasion, I will use warm water. I even will use3 a light spray of household deoderiser to keep it from smelling. As mentioned earlier in a post, I also use a pste, and don't have a problem even at night. Keep it up, and stay in touch. As rule, I will get 6-8 days with my flange. Something worth mentioning also, is that I purchased a beday, and what a difference it has made in cleanning out my pouch.
