Ethyl alcohol is a poor sanitizer.... the only research done on it was done with 100% back in the 60-70's .... it was only tested on 4 different bacteria and its exposure time was long ... take this same research and apply it to Purell for your hands... it makes people feel good but does little else... stick with chlorine to sanitize... as for the people who never sanitize... it only takes one case of giardia or some other nasty bug to change your mind / life... its like the flu vaccine .... it only takes one case of the "real" flu to convince you to take it every year...
