Dettol these days, since they bought over Lysol...doesn't smell that strong or concentrated anymore. Dettol mixed with water will still be cloudy in appearance. Hospitals in the old days smell of Lysol, that was the disinfectant they uses to clean the wards etc.. Areas where they need to be germ free, in other words hygienic, I smell Eusol. These are the two smells I associate hospitals with, till this day.
