The reason why antiseptic claims are always qualified like this is not always because the amount they kill is truly measured at 99.9 percent, but because below a certain level there is no sufficiently sensitive test that confirms the complete absence of microbes, making a claim of completely destroying them impossible to prove. Even highly effective sterilization methods such as ionizing radiation can therefore only provide a claim of a quantifiable reduction, as opposed to complete eradication, even though that can be reasonably assumed.
