Abstract
A portable eyeglass cleaning kit is provided with a chemically treated pig skin chamois housed within a small portable plastic storage case. The chamois is treated with a chemical mixture for more efficient eyeglass lens cleaning. The chemical fixture serves as a fungicide for inhibiting the growth of mildew while the chamois is stored in the case. The chamois can be maintained moistened in the air-tight storage case or dry to be moistened when needed. The storage case is affixed with a detachable chain which enables the unit to serve as a key chain or be attachable to one.
