Abstract: A backing for a jewelry article includes an outer casing surrounding a chamber storing a disinfectant. Aligned apertures are formed in opposing walls of the backing for allowing passage of a mounting post therethrough. Sealing membranes are retained proximate the apertures to prevent disinfectant from leaking out of the chamber, while permitting the post to be passed therethrough. An absorbent material is housed within the chamber of the outer casing for absorbing the disinfectant disposed within the chamber while permitting the post to pass through such absorbent material. The post is passed into a first aperture, through the chamber, and out of a second aperture for bringing the disinfectant in contact with a majority of the post.
