Trial and error has led me to a system of emptying and cleaning my pouch that makes everything feel better. I saw another post about using warm water in the pouch after emptying to wash it out. I will say it takes several times of doing this (put water in, holding the pouch up, swish it around, then empty) to get it clean. I do this until the water runs clear when coming out. I also use a deodorant each time I'm done (into the pouch before closing up). Everybody has a different body's chemistry, but safe and simple unscented seems to take care of all in any odor. Hope this helps someone in any way. Have a happy day.
