Abstract
Tubes (12), which can have any variety of cross-section and multiple bends, to be cleaned each have one end portion retained within a fixture (16) by an expanded bladder (42) while pressurized cleaning fluid (52) from conduit (50) passes through the tubes (12). Where no tube (12) is positioned within a particular fixture (16), the cleaning fluid (52) is prevented from moving through the fixture by the expanded bladder (42).
