How Does It Work?
Prior to storing hydrogen peroxide in an aluminum container, the container can be passivated by rinsing it with a dilute solution of nitric acid and peroxide alternating with deionized water. The nitric acid and peroxide oxidize and dissolves any impurities on the inner surface of the container, and the deionized water rinses away the acid and oxidized impurities.
