A method for cleaning a paint spray gun, which comprises a rotating atomization head to apply a coating material while rotating and an outer circumferential tube to cover the exterior of the rotating atomization head, has a cleaning solution application step for applying a cleaning solution to the external face of the outer circumferential tube, and a rotating atomization head rotation step for generating a rotational flow between the rotating atomization head and the outer circumferential tube by rotating the rotating atomization head. The cleaning solution flowing down the external face of the outer circumferential tube applied in the cleaning solution application step penetrates between the rotating atomization head and the outer circumferential tube by way of the rotational flow. Such method uses a small amount of cleaning solution for cleaning external and internal faces of the outer circumferential tube and the external face of a rotating atomization head.

A wash station includes a wash nozzle for cleaning an exterior portion of a probe and a basin allowing for waste fluid to be collected. The wash nozzle includes a vertically-elongate cavity with side slits on opposing side portions. A fluid inlet port may be connected to a side portion of the cavity to provide fluid. Fluid may additionally or alternatively come from within the probe. The basin includes an elongate body with an opened end to receive and secure the wash nozzle. One or more access slots may be provided on opposing side portions of the basin. The probe passes through an access slot or over a portion of the basin and through a side slit of the nozzle to enter the cavity for cleaning. A geometry of the cavity allows the wash nozzle to fill to a predetermined level while waste fluid flows out through the side slits.

The present disclosure is directed to endoscope cleaning systems and methods. The endoscope cleaning system can include a pump housing that houses a peristaltic pump, an endoscope sheath fluidly connected to the pump housing, and a pump control communicatively coupled to the peristaltic pump. Upon activation of the pump control, the peristaltic pump can supply fluid to the endoscope sheath for cleaning an endoscope. Upon deactivation of the pump control, the peristaltic pump can remove residual fluid from the endoscope.
