Germs

My bottle of hand sanitizer reads, "Kills 99.9% of germs without water." What are the other .1% of germs out there that hand my hand sanitizer does not kill? If I use water with my hand sanitizer, then will it kill all 100% of germs? How does the ambiguous They find this out? Do they test hand sanitizer one germ at a time, or do they put thousands of germs on some poor soul, then perform an autopsy to see what germs killed that person?

Hand sanitizer makers should put a list on the bottles describing exactly what germs it kills:

"Acme Hand Sanitizer kills germs that cause the common cold, influenza, e.coli, conjunctavitis, and salmonella. If you come into contact with any germs other than the ones listed, you are screwed and should start planning your funeral or making sure your insurance is current. Please quarantine yourself from the rest of society and burn everything you have come into contact with, so as to not chance selfishly spreading your germs to the rest of mankind and possibly destroying all life forms as we know them. We do not want medical and malpractice insurance to be driven up, just because your sorry ass was too lazy to sneeze into a tissue, then kindly throw it away, or for F sake, decide that you were in too big of a hurry to wash your hands!"
