A method of cleaning a cylinder head using pressurized fluid and a tooling assembly for the same includes a jet ignition insert attached to a spark plug well defined by the cylinder head. The insert defines an opening in fluid communication with the spark plug well. The insert includes an end wall attached to the insert distal end to close one end of the opening and the end wall defines holes. The tooling assembly includes a tool configured to clean the insert. A first engagement surface of the insert and a second engagement surface of the tool engage each other to form a seal that surrounds the holes of the insert such that the pressurized fluid is directed through the holes and into the opening of the insert during the first operation procedure of the tooling assembly to flush debris out of the holes of the insert.

A method of cleaning a contaminated surface, such as cleaning the elongate interior lumen of an endoscope contaminated with flesh, bone, blood, mucous, faeces or biofilm, said method comprising the steps of: providing a suspension of solid particles in a liquid to said contaminated surface, and flowing said suspension along said surface thereby to remove contaminant from the surface. The suspension is preferably a paste, where the solid material may be e.g. crystals of a salt, silicon oxide or organic material. The paste preferably has a solid fraction between 5 and 55%. A rheology modifier may be present.

The present disclosure relates to a method for cleaning a sampling pipeline of a sample processor, wherein the sampling pipeline communicates a flow cell to a sample source of the sample processor. The method comprises: a forward rinsing step of rinsing the sampling pipeline in a first direction by using a sheath liquid or a cleaning liquid different from the sheath liquid and provided via a cleaning liquid pipeline; and/or a reverse rinsing step of rinsing the sampling pipeline in a second direction opposite to the first direction by using the sheath liquid or the cleaning liquid. The present disclosure also provides a pipeline system for implementing the above method and a sample processor comprising the pipeline system. The method, pipeline system and sample processor according to the present disclosure have significantly improved cleaning effect.

A method and device for purifying fluids in a container and providing a system for the cleaning of a container in automated analyser systems, comprising a pump which is connected to a single injection nozzle, wherein the single injection nozzle is configured to provide an oscillating fluidic jet, as well as a method for the cleaning of a container in automated analyser systems, comprising the following steps of arranging a container in a mount below a single oscillation nozzle; providing a cleaning fluid to a pump, which is connected to a controller and the oscillation nozzle; aligning the oscillating fluidic jet to a surface of the container which is to be cleaned; applying a cleaning fluid through the pump to the oscillation nozzle; and cleaning a surface of the container with the cleaning fluid.
