The proposes using the Hydroxyl Radical Sterilization Method to clean sensitive equipment and workspaces. The process includes two steps. First, the cold vapour of hydrogen peroxide generated and allowed to penetrate porous surfaces, cavities, vents in equipment and other complicated and hard to reach surfaces in rooms, vessels, aircraft and vehicles. Due to a relatively high boiling point (150.2 °C), hydrogen peroxide tends to concentrate on solid surfaces. When the required concentration of hydrogen peroxide in the air is achieved, it is mixed with a limited and controllable amount of ozone added to the air in the treated space, and this is the second step.  Ozone reacts with hydrogen peroxide by a reaction known as the peroxone oxidation that generates shortliving hydroxy radicals (OH·). Hydroxy radicals have very high disinfecting activity, much more effective than ozone or hydrogen peroxide alone. The final products of ozone and hydrogen peroxide reaction are harmless water vapour
