Bleaches work by changing the structure of color-producing groups called chromophores to make them colorless. This chemical reaction breaks down the chromophores, thus removing the color from the stained material. Bleaches contain chemicals like hydrogen peroxide, sodium hypochlorite, sodium bisulfite, and sodium hydrosulfite that react with the chromophores to alter their structure, resulting in no visible color.
