Bleach then becomes simple salt and water with no free chlorine molecules, meaning that there is no risk of chlorine gas being produced unless it is mixed with an acid or ammonia.

What happens when bleach evaporates?

That’s because the sodium hypochlorite active in Clorox® Regular Bleach2 breaks down into salt and water (a big part of what makes it so environmentally friendly). Also, note that undiluted bleach is mostly water – as the water evaporates, eventually salt crystals will remain.

Does bleach evaporate from water?

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 it take for chlorine to dissipate?

Bleach dissipates quickly, meaning it disappears from the surface it’s used on. As long as the bleach has dried completely the surface is safe to use. Where as Lysol and the Clorox wipes leave a residue.
