Abstract
A file includes a support member having an abrasive surface treated with a sanitizing agent. The surface or the interstices between particles of abrasive hold the sanitizing agent which is released with use of the file. The sanitizing agent is either in a liquid carrier or contained within microcapsules. The microcapsules are frangible and break upon use of the file to release the sanitizing agent. The file surface may comprise granular abrasive particulates having a size ranging from 40 to 1200 grit which provide the interstices between at least some of the particulates. An aqueous coating having dispersed therein an adhesive and the microcapsules is applied to the granular particulates. The coating is dried to deposit in the interstices the microcapsules. The adhesive binds the microcapsules to the granular particulates. When a mixture of sanitizing agent and liquid carrier is used, the abrasive surface is coated with the mixture and then the carrier is removed to coat the surface with the sanitizing agent.
