A cleaning apparatus uses an ultrasonically excited cleaning fluid to clean an object disposed in a cleaning chamber that is substantially isolated from a surrounding environment. The apparatus is particularly suited to cleaning a portion of an elongate member, especially (but not necessarily only) an intermediate (i.e., a portion excluding a distal end portion) portion thereof. In one example, the cleaning apparatus is usable to clean only an intermediate portion of an optical fiber stripped of its coating. The cleaning fluid may be, for example and without limitation, an alcohol such as isopropyl alcohol, or acetone. The cleaning fluid may be circulated in a closed circuit. The closed circuit may include one or more of a fluid pump, a vacuum device for further urging the fluid through the system, and a fluid filter for cleaning the used fluid of at least some contaminants before it is reused.
