Chlorine as a gas is dangerous to both environment and all the living. Bleach is formed from chlorine gas and caustic soda by some process usually sold as 12% sodium hypo content in the solution. When sold to household as bleach, it is usually around 5% content.
Water treatment and swimming pool usage is controlled usage of sodium hypo to keep a range of usually 0.1 - 0.5 ppm residual free chlorine inside the water to kill the germs in water. It is not for selective killing thus very effective for both application. The residual free chlorine inside irritates your skin and makes your eyes reddish if you not using goggles, so does that stop you from swimming and drinking from the tap water? Of course in not controlled use, the more ppm than that then the volatile chlorine becomes corrosive to environment and above 1 ppm, it is also more irritant to your skin and soft tissue like eyes. That's why it is a controlled usage.
I talk with microbiologist before and I will keep using ammonia as spray, again under consideration of simplicity, effectiveness and controlled, but I don't have much experience using ammonia as disinfectant compares to bleach and alcohol, as I don't like the odor a lot. I can't stand vinegar odor, and ammonia is worse to me.
So between alcohol and bleach? I personally will use bleach wisely as I know the knowledge and it is much cheaper than others.
