Unscented Air Deodorizer? Does anyone know of a product that will take precision of teenage-boy...

Does anyone know of a product that will take precision of teenage-boy odors, but not leave any scent losing? My son's room always smells kinda funny, but he doesn't approaching the smell of air fresheners. There are so plentiful choices at the store, but I have no theory what really works. Thanks!
Answers:    Oust actually have an unscented spray. I am allergic to most fragranced sprays, so I was fundamentally excited to finally find this product. It smells just a moment or two at first (basically enough so that you know it is in actual fact spraying) and then go away quickly.
