Abstract: A method for removing plasticizers, oils and other liquids concentrated in areas contiguous to the outer surface of a coverstock of a bowling ball. The method includes the steps of formulating a plasticizer absorbent material; applying the formulated plasticizer absorbing material to the outer surface of the coverstock; allowing the applied plasticizer absorbing material to remain in contact with the outer surface of the coverstock for a defined time period and removing the plasticizer absorbing material and the extracted plasticizer from the coverstock. The plasticizer absorbing material is formulated of one or more of fine soft pine wood dust, silica gel and sphagnum peat moss and or synthetic or natural microfiber material.
