Scent Thief Spray is a scent blocker that blocks most scents and odors. It comes in a 24 oz. spray bottle. Scent Thief relaxes an olfactory epithelium in both humans and any other animals. The olfactory epithelium is located in the nose and is a key part of sending odors to the brain. With the olfactory epithelium relaxed an animal can no longer smell odors of any kind past Scent Thief. Simply spray down everything that has come into contact with human odor (or any foul odor). When spraying, be generous because the more Scent Thief you apply the more the olfactory epithelium is going to be relaxed.
