Dear Robert, Antibacterial cleaners do not contain antibiotics but
quite strong antibacterial chemicals (best known is hypochlorite and
bleach in cleaners). No bug is likely to develop much resistance
against that, best not taken internally!
But I wonder, is there anybody who knows the mystical active ingre-
dient in Dettol, or is that a trade-secret?
