ABSTRACT:
A two-chambered cleaning device includes an upper chamber and a lower chamber separated by a generally horizontal perforated plate. Generally vertical openings extend through the horizontal plate constituting the perforations which receive generally vertical open tubes extending above the horizontal plate into the upper chamber. The vertical open tubes receive the open ends of closed-end tubes which are to be cleaned. A cleaning liquid is introduced into the upper chamber, above the horizontal plate. The pressure in the lower chamber is reduced below that of the upper chamber whereby the cleaning fluid passes upwardly through the annular space between the outer surface of the vertical open tubes and the inner surface of the closed-end tubes which are to be cleaned.
