A handheld plumbob cleaner for efficiently cleaning a plumbob after measuring fluid in a storage tank. The handheld plumbob cleaner generally includes a frame portion, a handle portion extending from the frame portion and a cleaner attachment secured to the frame portion. The frame portion includes a slot leading to a central opening and a plurality of fastener apertures positioned around its outer perimeter. The cleaner attachment similarly includes a slot leading to a smaller central opening and corresponding fastener apertures around its outer perimeter. The cleaner attachment is secured to the frame portion via one or more fasteners. The gauge tape of the plumbob may then be inserted within the slots and the plumbob pulled up through the central opening to squeegee oily residue therefrom.
