Why should bleach not be stored in a metal container?

Storing bleach in a metal container is not advisable because bleach is a strong oxidizing agent and can corrode many types of metal. The active ingredient in bleach, sodium hypochlorite, can react with metal containers, leading to the breakdown of the metal and potential contamination of the bleach itself. This corrosion could weaken the structural integrity of the container, posing safety risks, and can also reduce the effectiveness of the bleach if it becomes contaminated. Therefore, using a non-reactive container, typically made of plastic, is essential to ensure both safety and product efficacy.
