Muzzyman... you don' t get it out by washing. You get the absorbed ordors out by heating the thing to a high heat forcing the molecules to be released from the carbon. They all can' t be released so overtime the suit does become fully USELESS. They tell you up front the things are only good for a couple years(depends on how much you use it, sweat, climate etc. BUT, it can be rejuvenated to some extent with high heat.

Mike in Texas... I believe your Zip Lock storage bag IS plastic and it' s made from petroleum distillates.
