An improved apparatus which can be used for cleaning and/or sterilizing tubular items. A container is partitioned into two chambers with the item to be cleaned and/or sterilized is positioned to extend through the partition such that one opening lies in one chamber and another opening lies in the other chamber. Pressure is applied to one chamber forcing the liquid to surge into the second chamber. The surging affect is facilitated through the use of either a flexible membrane in the second chamber, or the use of dual pistons which are one hundred eighty degrees out of synchronization such that one chamber is being pressurized while the second chamber is be de-pressurized.
