Ozone machines and a bowl of vinegar can help deodorize a space. However, the faint smell of death can linger even after cleaning. Complete elimination of this smell depends on several factors, including absorption of body fluid odors into porous objects, the physical structure of the death scene, and objects contaminated by gases and fluids. Equipment available to help deodorize a space includes ozone generators, misters, foggers, pump sprayers, trigger sprayers, vapor modification units, and hydroxyl generators.
