why only 99.9% of germs dead?
In article ,
says...
I keep seeing adverts that state that the product kills 99.9% of germs
dead. What can't we have a product that kills them all, like Screen?
The approvals standard with which bleaches and such things have to
comply requires that 99% of the sample population of bugs be dead after
certain time at a certain concentration.
Of course, in most cases this is exceeded, but the rules state 99%
minimum, and that's what they're rated at.
