I take mine and run water in it from the garden hose outside and shake the water out. I do that about 5-10 times and then I put an ounce or two of water in it and hang it up outside just like I would if it had scent in it. I've found that by the time the water has all dripped out of it, the smell isn't bad. I then store it in a ziploc bag.
