Miniature decorations and service medals are worn in ascending sequence from right to left, with the highest precedence medal worn on the top row if more than one row is necessary. When four or fewer miniature medals are worn in the same row, they are worn side by side and may be overlapped. However, when five or more miniature medals are worn in the same row, they are spaced apart enough that no overlap occurs. Medals worn on the uniform should be clean and free of tarnish. They should also be kept away from moisture and heat sources until needed for wear during ceremonial events. Uniforms are cleaned with a special brush used for clothing before being sent to storage. The miniature decoration area is then washed with soap and water to remove any powdery residue that might have accumulated during production.
