Bleach rapidly degrades in the presence of light and when mixed with water. 4. Bleach solutions require a full 10 minutes of contact time to ensure complete disinfection. If bleach solution evaporates in less than 10 minutes, a greater volume of solution should be applied.
Herein, does bleach evaporate?
Bleach is a solution of sodium hypochlorite in water, and since sodium hypochlorite is not volatile, but is a white solid at room temperature, it will not evaporate and will be left behind when the water evaporates.
Similarly, how long does bleach stay active on a surface?
Diluted household bleach disinfects within 10–60 minutes contact time (see Table G.1 below for concentrations and contact times), is widely available at a low cost, and is recommended for surface disinfection in health-care facilities.
Generally, bleach stored at room temperature (~70°F) has a shelf life of one year, but after that point it should be replaced. Since you don't remember when you bought your bleach, and it has no bleach smell, it is definitely quite old.
