ABSTRACT:
A flexible cleaning tool for cleaning corrosion from the contact arms and barrel of electrical jacks in which the structural integrity of the contact arm necessitates a reduction in the displacement of the contact arm during the cleaning process. A low density polyethylene shaft, having one or more diameter reductions, is inserted into the jack and manipulated by moving the handle, whereby the flexibility of the shaft allows the shaft to bear upon the jack contact arms and jack barrel interior in a manner which is highly conducive to efficient and thorough cleaning. When the shaft diameter is reduced at the point of contact, the displacement of the contact arm by the shaft is reduced. The dislodged corrosion attaches to the shaft allowing the corrosion to be transported from the interior of the jack enclosure where it can be easily washed from the shaft.
