Question for you

If hand sanitizer kills 99.9% of germs and you use it twice in a row, does it kill the remaining .1% or 99.9% of the remaining .1%?

Anyone know?

It's 99.9% of known germs that might be found on your hands. What they're saying is that there are likely germs against which it has not yet been tested. It's 100% of the germs they know it can kill. I like the thought process, though. It made me laugh.
