A non-sterile solution intended to be applied to a surgical instrument prior to sterilization for purposes of lubrication/maintenance (e.g., to prevent moving or mating parts from sticking together during use, inhibit corrosion, and to improve longevity of the instrument); it is not dedicated to a particular type of surgical instrument. It may be a water-soluble solution, commonly known as instrument milk because of its white colour when mixed with water, in which the instrument is immersed, or it may be a spray that is sprayed onto the instrument. After application, this device cannot be reused.
