How does metal react to bleach?

Metal can react with bleach (sodium hypochlorite) in various ways, depending on the type of metal. Some metals, like aluminum and iron, may corrode or tarnish when exposed to bleach, leading to oxidation and degradation. Stainless steel is generally more resistant but can still be affected, resulting in pitting or discoloration. It's important to avoid mixing bleach with metals in cleaning or maintenance applications to prevent damage.
