The benefits of using ozone for restoration work are many. Smoke odor molecules that infiltrate porous surfaces can be permanently oxidized and removed. And ozone is effective on the most stubborn of all odor molecules -- protein. Odors associated with dead bodies, freezer failure have long resisted normal chemical deodorizing attempts.
Hydrogen Peroxide, mild bleach, forms when ozone is exposed to sufficient moisture, so certain textiles should be removed.
