Febreeze will mostly just cover up the smell, plus leave a residue. For items that originally are meant to be washed in water (cotton P41s for instance) handwashing with a small amount of white vinegar will often work very well. It also deodorizes the item, and leaves no residue. Hang dry on a drying rack or good hanger that won't distort the shoulders. The key is to make sure it dries fairly quickly. If indoors, use a fan, or better yet, hang it where the outdoor breeze or sun is on it for a short time. The UV of the sunlight will also disinfect and deodorize it, in addition to drying.
