I have a friend who's girl friend had a house cleaning business. He bought an old '72 Chevy van to restore. It smelled like a gang of bridge bums had been living in it. He tried everything to get the stink out, nothing worked. She gave him a can of Ozium. He hosed the inside down and let it set a few days. It worked great. It's kind of like Fabreez on steroids. Breathing it for a short length of time will make you queezy, so do it in a well ventilated area. See the link...
