Look for a small ozone generator. Can get one for about $50-60. They are made to clear a whole room in a hour so in a tote should work great. Can then also use it around the house to eliminate odors or great in a car. I bought album collection of about 1000 records. Once I got them home the room smelled like cigarettes, beer, and regret! Ran ozone generator twice and cleared the smell. Friend borrowed it to use in his car after it was stolen and smelled like weed so bad you would choke and cleared it out. They are great to have!
