The disclosed hydrogen peroxide indicator includes a substrate on which is disposed an indicator composition that includes at least one of a select group of indicator compounds and a catalyst. As a result of contact with hydrogen peroxide, the indicator composition changes color, even from colorless to having a visually observable color, thereby providing an indication of the presence of hydrogen peroxide.
