Abstract
This invention relates to a device for cleaning and decontaminating rods, shafts or other long tubular materials. In particular, the device cleans and decontaminates rods that are used in downhole remediation tasks that might otherwise transfer contaminants out of the ground. The device scrubs, washes, rinses and dries the outer surface of the rod while recovering the wash and rinse fluids and any soil or other debris scrubbed from the surface of the rods. In one variation, the rinse fluid is recycled for use as wash fluid to conserve fluids used in the field.
