The invention relates to a method of cleaning and/or sterilization of an object provided in a hermetically sealed enclosure, providing a pressure difference between an internal volume of the enclosure and surroundings and generating a plasma solely inside the enclosure for said cleaning and/or sterilization of the object. The invention further relates to an apparatus for enabling the same. The apparatuscomprises a vacuum chamber, which can be evacuated using a vacuum pump, and a sourcearranged to generate plasma of a suitable gas in an enclosure, which is substantially hermetically closed with respect to the atmosphere of the vacuum chamber. The enclosuremay be of a flexible type or may be manufactured from a rigid material. In case when the enclosure is rigid the pressure inside the enclosure may be lower than an outside pressure.
