1. A pin wash station, comprising:
- a lower chamber;
a drain basin;
a plurality of cleaning tubes, each cleaning tube having an inlet end and an outlet end, each tube inlet end being in fluid communication with the lower chamber, the terminus of all tube inlet ends being below a substantially horizontal reference plane, each tube outlet end being in fluid communication with the drain basin such that fluid that exits the outlet end of the tube passes into the drain basin, and each tube outlet end adapted to receive at least a portion of a deposition pin; and
a vent tube, the vent tube having an inlet end and an outlet end, the inlet end being in fluid communication with the lower chamber, the terminus of the vent tube inlet end being above the level of the cleaning tube inlet ends relative to the substantially horizontal reference plane, and the outlet end being in fluid communication with the drain basin, wherein the plurality of cleaning tube outlet ends has a feature that creates rotating or agitated flow pattern.
