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.

Method of treating the coverstock of a bowling ball to improve performance

A bowling ball has a heavy core of given density; the core has an asymmetrical shape that affords no planes of symmetry. The core is encompassed by a spherical shell of lower density; the shell may include two layers, a relatively hard outer layer of an acrylated resin or urethane resin and a more resilient, softer inner layer, usually of urethane or filled polyester resin. A balancing weight, to compensate for finger holes to be drilled into the shell, is preferably an integral part of the bowling ball core. The density of the balancing weight is usually greater than the density of the rest of the core.
