I have tried everything suggested in a number of similar threads - Fbreeze, Funk Free, etc. Those work pretty well, but this stuff is fantastic: MiraZyme. You fill up a bucket with water and a bit of that stuff, soak your gear for 10 minutes, and hang it up to dry. All odors gone. It is a bunch of naturally-occuring enzymes that essentially eat the odor-causing bacteria. You can get it lots of places - REI, Campmor, etc.
