A portable apparatus (100) cleans a passage such as an oxygen line (600) by circulating a cleaning medium (200), such as silicated medium: A rinse medium, such as distilled water, may then be circulated through the passage. The cleaning medium (200) and the rinse medium (300) may be filtered, and a flush medium is preferably circulated through the passage after the circulation of the cleaning medium (200) and before the circulation of the rinse medium (300).
