A mobile apparatus for supply and collection of cleaning fluids used in field cleaning of pipe threads preparatory to oil field drilling operations is described. The apparatus includes a moveable cart structure defined by a chassis with wheels. An upper frame member is connected to the chassis by a plurality of scissor jack assemblies which may be independently extended or contracted to raise and lower the upper frame with respect to the chassis. A basin for receiving pipe thread cleaning solution is affixed to the movable upper frame member and depends therefrom. A flow control cover including a pair of pivotable panels interleaved at their inner ends over the central portion of the basin is provided to substantially cover the basin. The panels are movable to an inwardly sloping position to collect and funnel cleaning fluid back into the basin for periods of active use. The panels may also be moved to a raised sloping position to provide a protective roofing cover to prevent ingress of environmental moisture or particulates into the basin. Shrouding elements may be secured to the upper frame to provide water tight seams along the sides of the flow control panels. A hose and pump assembly may be included to withdraw fluid from the basin for use or to remove spent fluids. The apparatus includes features which permit it to be stored out of doors in the field without risk of contamination to or from the environment.
