Hey Mike, I went to work with my dad when I was a kid at a place called unifirst. Like many others, its a uniform cleaning company. The plant also cleans its water for recycling. One of the worst smells in the world. Also when they receive bar towels to be cleaned, they come out of bundles of formenting beer and plenty of maggots. I never though the process of cleaning stuff could be so dirty. Hope this helps on your quest for more dirty jobs. Have fun with your endevors
