I have a pair of ankle zipper neoprene boots for kayaking. Don't know if they are 3 mil or 5 mil thickness. They are stinking and do not want put them into some kind of solution and have them fall apart. What does everyone do to clean the smell out of them? My reefrunner shoes I use in the summer smell also and seem to be made of some of the same kind of materials. Thanks for the answers.
