How long does it take for bleach to dissipate?
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.
Beside above, how long does it take for chlorine to dissipate? Depending on its levels of content, the evaporation time for chlorine from tap water can be estimated: 2 ppm of Chlorine will take up to 4 and a half days or around 110 hours to evaporate from 10 gallons of standing water. Ultraviolet light, circulation, and aeration will speed up the process dramatically.
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.
How long will bleach smell last?
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.
