I've read so many stupid posts.... but never seen such an uninformed, irrational nonsense as you come out with.
Hospitals do not use "chlorine"..... what does chlorine smell like? try the swimming pool - do I read you write? Wrong, the smell at a swimming pool is the waste product of chlorine interactions.
hospitals rarely use any disinfectants as it was found that such cause bacteria to develop/mutate resistance to cleaning agents. eg MRSA was the result of excessive disinfectant use in operating theatres. hence disinfectants stopped being used in NSW in the late 80's.
